Nightmare - External hard drive crashes to floor
« on: February 19, 2010, 03:21:17 am »
Not sure where this goes, but didn't know who else to turn to for honest help.

Damned if I didn't do a stupid thing about three weeks ago. I was moving video files, via my laptop, from our old Iomega external HD.  Both were sitting on the top of a short bookcase in our bedroom, maybe 3-4 ft tall (yes, another bonehead idea, but anyway). My wife had gone to work, and my kid had just about driven me crazy. Without thinking I went to move the laptop off the bookcase to the bed, and....yep, you guessed it - the HD was still wired up.  On a hardwood floor, no less.  Sounded like a damn bomb went off when it hit, but it landed flat (like that matters), not on its side.

I have little doubt that the arm is out of sync, with the clicking noise I heard when I powered it back up. I've done research via google, and it's not overly encouraging.  I have tried various "freeware" data recovery programs, but have not found anything that finds the drive - or if it does, I don't know what to do next with it.

I am still out of work, so a data recovery service is completely a useless idea for now. Thought about opening it up, moving the arm back, and then trying to copy the data, but that's a bit out of my complete comfort zone.

We are just wondering at this point if I totally toasted it and there's no hope of getting the data back.  The only truly valuable things we will have lost are pictures of our little one that my wife had not yet moved from it...everything else is "redoable" as most of it was downloads....it'll just take forever and a day.

Any help - your suggestions for data recovery program, a cheap data recovery service, etc. is greatly appreciated.  I've been  :censored: at myself for three weeks now - and like I said, while I see info on it online, can't make heads or tails of some of it after getting started.  Thanks ahead of time!

Can't be certain if I am not there to look at it, but it may just be ---fouled up beyond all recognition---. One suggestion would be to use a program called SPINRITE to recover data. It has been around since the 80's (even a computer chronicles ep about it) and is updated every few years. It costs like 80 bucks, but is considered a must have by every computer nerd on earth (PC, MAC, Amiga, Linux, etc nerds). It only runs on PC, but can read and recover data on almost any formated drive. One thing you may have to do tho, is to remove the HDD from the case and use an adapter to connect it directly to a full fledged PC.

Outside of that, I cannot stress enough how much you need to BACKUP data, not just move it. Simply buying a stack of 40 DVD-r's for 20 bucks and making 2 copies of all of your most valued stuff (on top of the copy on the HDD) is more important than anything. Not to chide you, but backing your data up is a pro-active thing and is cheap in comparison to recovery (if possible).

Anyways, check out SPINRITE, it is the only program I know of that will do low level reads and can even read over "destroyed" data multiple times to get a heuristic "idea" of what the 1's and 0's are on a damaged track.

Sorries.

External hard drive eh?  They are capable of withstanding falls from 6-8 ft.  Heck I had one bounce down some concrete steps in our old apt and it survived.

Well for a start I would open her up.  Sounds like power is not getting to the drive (clicking sounds).

Find out what the interface is and try to power it via your laptop/PC.

I know its late saying this, but when you have some pennies or a spare PC kicking around - convert it to a NAS, and BACK EVERYTHING UP.

If it is truly shagged, then find the same drive and manufacturer and buy another one. 

You might just be lucky enough and find that its just the main board is damaged.

Swap the main-board and get the data off.

Spinwrite wont help you.  But it is at www.grc.com 

Good luck!

Simply buying a stack of 40 DVD-r's for 20 bucks and making 2 copies of all of your most valued stuff (on top of the copy on the HDD) is more important than anything.

Uh... it's a little more complicated than that. A DVD's half life is meager at best. Bought a stack of 100 HP DVD+R and they noticeably lighter than the last stack of TDK DVD+R I bought. Would've bught another TDK spindle, but no one carries it anymore. I expect the HPs to delaminate or get some bit rot before the TDKs. The HPs look and feel more like CDs of yesteryear. :badmood:

But I digress. If you're making two copies of your files (as you should) use two different manufacturers, not just brands. Go and download DVD Identifier (If you have to pay for it, you're being ripped off). Use the tool to identify your spindles until you find two that are from different manufactures. There are websites that help clue you in, but it's hit and miss. Maxwell changed manufacturers and I got a crap spindle of black archivals once. When you have two spindles from different manufacturers then make your backups.

Having two different manufacturers for your discs reduces the likelyhood that both will delaminate or experience bitrot at the same time.

If you don't think you'll experience bitrot, believe me, you will. I have burned CDs from the early days that are already failing. I lost about 20% of my old custom Carmageddon files because of this ---smurf-poop---.

I have completely abandoned optical media for backup. I keep copies of my data in multiple places (original on each machine, duplicate on the server in the house, another duplicate on my work machine), but I think the most brilliant backup addition I did was to buy thumb drives. Stick important stuff on a thumb drive, and put it in my fireproof locking safe in the house. Small, relatively cheap, and getting bigger all the time.

Saint's got it right - optical media is too volatile. Best to keep your data on multiple devices in multiple places. I'm a little skeptical on how long jump drives would hold their data however. I personally have two mirrored 1TB drives where all my pictures and crap resides.

RTS - sent you a PM...

Do you have those elsewhere as well Havok? Mirror will protect you from a drive failure, but not something happening to the volume or disaster in that machine, house fire, etc...

I'm uncertain as to the longevity of jump drives myself. Eggs in multiple baskets for sure!

That's the thing - I have them both in my home office. They're external for easy access, but you're right - I probably should periodically grab an image of the drive and store it offsite in case of home disaster. I like the idea of "borrowing" space on my work computer, I think I'll be using that hard drive on my laptop a little more fully now...

Was the drive on when it fell?  If so, it's probably toast.  If not, it probably survived, but the little board that's hooked up to it to do the USB or whatever side of things may have gotten loose or damaged.  If it's doing a "click", "click", "click" thing with a regular interval after spinning up, then it's almost certainly gone beyond any recovery you can attempt.  Generally that means that the firmware can't find its position for the armature.  Cause is usually a "head crash" or a bad position/limit sensor.

The thing to do is yank the drive out of the enclosure and hook it up to a PC directly.  If it at least shows up in the BIOS as present, you've got a good start.  You can then attempt various recovery methods on it such as spinrite.  Even just using a Linux live CD can sometimes let you see things Windows/DOS will choke on.  Probably a good idea to keep everything mounted read-only if you do get any access, just in case.  If you do get access, you may want to image the drive to another drive or file then attempt more complicated recovery "offline".

If you can't get any of that to work, you have a couple last ditch options.  These options are mutually exclusive since the cheap option tends to destroy the drive entirely if it doesn't work, rendering the expensive option impossible.

As a cheap option, you can chuck the drive in a freezer overnight then attempt software based recovery methods again.  Sometimes the temperature change is enough to let the drive find all its alignment stuff and work *for a while*.  If it does work, copy off everything you can as fast as you can.  You generally only get one shot.  Only do this if the data is not worth spending the money for professional hardware recovery.

As an expensive but more reliable option, call up OnTrack or a similar company.  If there's data to be recovered from that drive, they'll get it.  Expect a bill in the upper 3 to mid 4 figures.  Some complicated recovery processes may even hit lower 5 figures.  Don't attempt to freeze the drive then send it to OnTrack when that doesn't work.  That generally just costs you more money or results in them being unable to recover anything.

Whatever you do, do NOT attempt to open the drive.  That will generally just kill it.  Tolerances on hard drives are so tight that a speck of dust can destroy them.

 You are better off keeping the drive closed until a day when you can afford a recovery specialist.
 
 The drive heads are small as a human hair, and once they hit the surface of the drive, it
destroys them, and even sometimes scratches the surface of the discs.

 I believe Ive heard of some people transplanting part from one drive to another drive of the
same model... however, if Any dust gets on a surface, you will just have ruined another drive.
As said, a single spec of dust can ruin an HD head.

When do you open a drive casing to replace the main-board?

There is a plastic trace connecting the main board to the drive assembly.   ::)

Protokatie and others:

You didn't hurt any feelings by reminding me to do backups.  The really stupid, sorry thing we did was when we bought the external drive, we bought it to " make room" by moving files to the EHD from our desktop....but the issue is, if we'd have only copied the pictures of our kid - instead of doing a move - we'd still have them.  Had that happened, this wouldn't even be an issue; I'd just chunk that drive and start over.

One thing you cured me of is thinking of opening the hard drive itself.  I had read online that sometimes if you open up the drive itself I could reposition the arm, but that sounds like a really, really bad idea.

So here's a thought - have you tried undeleting on the machine's internal hard drive to see if you can recover any of the files you moved?

i do not recomend what i done but it worked
had a internal hard drive in and external enclosure fall
all i got after that was a clicking
knew i wasn't supposed to but opened it up anyway the data on it was something i could collect again
i opened it up and turned it on and seen that the platters were not spinning i twisted them heard a crunch they started to spin after that
with a noticable scraping a vibrating noise but windows recognized it and it showed up in explorer
i started with the most important data first but there was a portion on the drive i could not access and when i tried it froze explorer up
tried it several times and could not get at that part it was about 2gb out of 200gb
 AGAIN I DO NOT RECOMEND THIS
just thought i would share it

Stick important stuff on a thumb drive, and put it in my fireproof locking safe in the house. Small, relatively cheap, and getting bigger all the time.

Like what was mentioned elsewhere, I haven't seen any reliable data on using thumb drives for long term storage. (I had to assist someone on that research about three years ago. I'm sure there must be some research? bleh) There's been extensive studies on optical media dating all the way back to the hideous LD stuff. You see it all the time when someone bitches about bitrot on the LD games.

There have also been studies done on the long term viability of HDD. The current accepted method for "storing" HDD for archival purposes is to actually disconnect the drive and store the computer and the HDD in a low temp environment. Obviously no studies have been done on bad caps  ::)

But Saint nailed it on the head. The key to storing digital records is duplication duplication duplication and to do it across as many different types of media as feasible.

I would actually suggest optical (and this is the reason why I suggested it) was for yearly updated off-site backup. That DVD-R isnt going to die in a year.

My basic thoughts for optical: Make two optical backup copies (this is on top of having another copy on your NAS so total of 4 copies) and keep one at home and another offsite (safe deposit box). Every year, recopy all the data to be backed up, label them, and store them. This way you are refreshing the data each year. BTW this is only for the MOST important of your data, which should normally fit on a few DVD-r's at a low cost per year. This sort of backup is so your most precious memories have a backup somewhere (and the yearly update will keep it up to date) (add to that any new data that should be copied immediatly)

When you generate backups, you have to consider a key human nature, laziness. I can guarantee that after three to five years of creating "yearly refreshes" of that data, a person is going to postpone the next refresh to next year. Then it'll be five years. Then you're going to work on that massive project which postpones it further and next thing you know, ten or fifteen or even twenty five years have passed.

You can't setup a archival program requires additional work and expect anyone to keep that up on a consistent basis. The best practice is to set up a "create it and leave it alone" kind of thing.

I always thought it would be an interesting project to build a disc juke box that does its own scheduled "maintainence" and backup of archived discs. For example, a database that earmarks DVDs for scheduled examination and data verification automatically generating new backups as necessary. But with the cost of HDDs and SSDs dropping faster than one could build such a juke, it's kind of a moot point.

SL, I see your point but another one that enforces periodic refresh is not only that HDDs die over time (electrolytic caps for instance) but that all standards are replaced about every 10 years. Luckily we will have USB and ATA/IDE/EIDE/PATA/SATA for awhile, but you cannot count on it. Even if the periodic backup was only once every few years, it would still be valid. On top of that, as far as laziness goes; we all make our own beds.

CD Standards change far faster than any other standard.  They also are the Worst when
it comes to backwards compatibility.  On top of that, burnable discs are not made to last
more than a few years.  The coating on them usually flakes off between 3 to 6 yrs.

 If you burned them at 50x today... and your burner stops working...  The new 100x burner
may not ever read the 50x discs.

 To keep on top of Optical Media BURNERS is far more expensive than to keep up with
direct Hard Drive backups.  Also, HD backups are far easier and 500x faster.
They are also a LOT cheaper per GB than Optical Media.

 Data can also be recovered from most any HD problem.  However, a single scratch on
the coating side of a disc, and its a coaster.

RTS,
Sorry about your drive and this thread.  I agree that you should leave the drive alone until you have the funds to properly retrieve the data.

I believe that's the reason why a PC is typically stored along with any HDDs in professional long term archivals. I know it would've been easier to have the equipment at hand instead of spending months trying to figure out and track down a multitude of antiquated media players on eBay and in museums.

The last research I dealt with prior to leaving my last job was cloud based storage. I don't necessarily agree with the concept for long term storage purposes (too many factors outside ones control and "live" data is always at risk for malicious corruption). However, that tech does neatly sidestep the issue of cap leak and bit rot. It's got enough support that a federal system is up and running designed to store federal and state archives.

saint's note - nasty bit removed...

http://www.fat-ntfs.com/articles/data-loss-problem/physical-errors/What-causes-a-Hard-Disk-Clicking-Sounds-323.html


You get that sound too if you are using a USB External drive (2.5) and USB 1.1.  you need adequate power for the drive to work, if it doesn't have it, the drive will click.  Thus my original post about opening the drive - meant opening the enclosure and testing the USB interface, by plugging the drive into a PATA or SATA cable.

External hard drive eh?  They are capable of withstanding falls from 6-8 ft. . . .

. . .  Sounds like power is not getting to the drive (clicking sounds).


An external hard drive is almost always just an internal hard drive screwed into a rigid case with no kind of shock absorption.  What kind of twisted logic makes you think external hard drives are likely to withstand a 6-8ft drop?  Also, if no power is getting to the drive, what in god's name is making the clicking sound?  Squirrels?  Elves?

 Ive experienced externals failing, however, to hear a click at all, you had to place your ear
on the drive itself.. and even then it was barely audible.  More like a light "tick".  I did however
hear a high pitched whine from even a distance away. 

 People who usually say they hear a Click, means they are probably hearing it Loudly and
from a distance.  ITs a very pronounced noise.

 I agree, that the drive could and should be tested outside of its external enclosure.
(but not opening the drive itself)

 I have the impression that it was already tested outside of the enclosure.

I have two of these and I can toss them down the stairs and they still work.  Got a Lacie 80gb that is the same but the USB interface is dying.  I might attempt throwing that out the window and see if that works.   ;D

The click is not demons or bats in the belfry.  It is from the drive motor.  Its real quiet......... :P

60GB? 80GB? Are we comparing laptop drives with desktop drives? And regardless of its size, those external drives are exactly what shmokes describes them as, internals with a nice jacket.

 You can "IF" they are not in the middle of a write operation.  An HD that is not active will Park
its heads so that they will not be able to get damaged due to vibrations.

 A Click is from the swing arms that holds the read/write heads.  Mostly, when the heads have
Crashed into the surface and jammed up.  Such a click is Very loud.  You can hear it from inside
a closed computer tower at times.

 If its so quiet you can barely hear it even against your ear... then its not really a click.
More like a skip/tick... which is probably the heads starting move, then getting parked again.
 
 The motor itself, is just about completely silent.  An HD is only heard, when its reading and writing.
When its spinning idle, there is no real noise made, because HDs use very high tolerance
bearings... and operate brushlessly.

Like what was mentioned elsewhere, I haven't seen any reliable data on using thumb drives for long term storage. (I had to assist someone on that research about three years ago. I'm sure there must be some research? bleh) There's been extensive studies on optical media dating all the way back to the hideous LD stuff. You see it all the time when someone bitches about bitrot on the LD games.

I looked into backup options a year or so ago (I posted a thread here about it) and noticed exactly the same thing. There is no information whatsoever out there about the suitability of flash drives for long term storage. If the manufacturers know the answer, they're not telling.

Flash drives are undoubtedly an incredibly convenient and durable method of storing data in the short term but there's a big question mark over whether they're suitable for long term storage. If I understand correctly, they use electrical charge to store their data. However, electrical charge (just like magnetic charge) tends to dissipate over time. And I'm guessing that the problem of charge leakage is likely to get worse as capacities increase.

As far as the durability of DVDs is concerned, I've seen estimates varying from 10 to 30 years for DVDs that have been properly stored. However, as the technology hasn't been around for that long, no one can really know for certain.

Personally, based on my own experiences, I'd say that the fragility of optical media has been somewhat overstated. The problem is that people tend to treat optical disks like crap and then wonder why they fail.

Most people I know think nothing of leaving disks in direct sunlight, and the disks I borrow from other people are invariably badly scratched.

I've also noticed that people often bend optical disks, sometimes quite severely. This is partly the fault of badly designed cases that won't release a disk without significant force being used. But still, people don't seem to care.

Anyway, as others have already pointed out, whatever storage method you choose to use, there's really no substitute for making regular copies of your backups.

Well all this talk about backup has made me rethink my own backup strategy, and since 500gb drives are under £35 its better than two weeks of DVD burning and cheaper too.

I wonder what strategies the normal every day user has, if any?

As far as the durability of DVDs is concerned, I've seen estimates varying from 10 to 30 years for DVDs that have been properly stored. However, as the technology hasn't been around for that long, no one can really know for certain.

We can make educated guesses.

LDs have been around since 1978 and exploded onto the market in the mid 80's (remember Back to the Future?) I don't have statistics at hand, but delamination and bitrot is extremely common with these. I'm not sure when the problems started, but it's been about twenty-five years for most of these discs.

CDs were introduced to the market sometime in the 80's (IIRC) and really took off in the 90's. I feel manufacturing qualities really changed. I had CD's from the late 80's early 90's that felt more substantial than current CDs sold today. That's about twenty years.

Finally, most companies cite accelerated weathering tests (similar to tests applied to cell phones and auto paints to determine product life expectancies).

It's generally accepted that pressed discs last longer than burned discs by nature of the requirements of both discs.

So..... given the studies on the accelerated weathering tests and the history of previous, similar, technologies, 10-30 years seems to be right around the mark.

Of course that is barring any extreme conditions, fire, mold, etc.

Whether from the motor or the arm, it needs power to move, and it needs to move to click.  The drive is getting power.

As for backup strategy, check out Microsoft's SyncToy.  This is a great utility for a basic, informal backup solution.  It allows you to keep two folders synced up, whether it's the My Docs folders on your laptop and desktop or the My Photos folder on your desktop and an external hard drive.  Changes made in either folder will automatically be reflected in the other folder in real time (or as soon as possible if the connection between folders is lost).

One thing I intend to do relatively soon, ie when I have a real job and can afford it, is start backing up to an online location for example with Amazon's S3 cloud storage offering.  I've never used it but Microsoft offers 25 GB of free cloud storage with Windows Live SkyDrive.  It requires a LiveID, but I'm pretty sure that by now everyone already has one.

As for photos, there's really no excuse to lose digital photos.  How many unlimited free services do you need before you get your photos backed up online?  Flickr, Picasa, Shutterfly, Photobucket . . . even Facebook.  Apps exist for all of these to automate the process so you can just mass upload your photos.  Get.  It.  Done.

FWIW, quality SLC flash devices (bare chips) generally specify 50-100 years retention at 25C going down to 10-25 years retention at 85C.  These are the guaranteed parameters.  You'll usually do much better.  MLC, the type used in most inexpensive, high-capacity flash storage devices, is usually only good for 10-25 years at 25C and 5-10 years at 85C.  It depends on the quality of the device.  Your high end Micron and Samsung devices will generally last longer than the cheapo no-name Chinese stuff.

Quality CD media stored in a controlled environment (dark, room temp, low but non-zero humidiity) should last 10 years or more.  You can buy special "archival" discs that will actually give you specs.  The Verbatim AZO (dark blue) are usually decent.  Quality DVD media is comparable.  All these specs assume you have a quality burner, which most people don't.  For your cheapo $35 CD/DVD burner, quarter the lifetimes.

As an anecdotal data point, I do have CDs burned more than 10 years ago that I can still read just fine, and they've just been stored in a standard jewel case in a dry basement, but they're on good media and from the era when you couldn't get crappy CD burners because they didn't exist.  I also have flash devices from the very early days of flash memory (mid 90s) that still work fine.  Again, they've just been stored indoors in a standard household environment.

You can pay more to get devices that have specified lifetimes and are tolerant of elevated temps or other environmental abnormalities.  Just expect to do just that: pay more.

In my opinion, the best backup system for your money right now is 2 external hard drives.  You do hard-link based incrementals using rsync (which are actually full snapshots in and of themselves, just only updating the stuff that's changed - this lets you go back in time while still making recovery easy) to one disk for a period (days or weeks) then swap in the other drive to do the same.  The drive that's not being used lives off-site.  Every year or two, you copy all the files to a new drive.  This builds in capacity increases and ensures that you have a "fresh" (from a physical point of view) copy of the data.  It will also let you spot any corrupted data (so make sure you check checksums when you do that) so you can attempt to recover that backup from your hopefully still good primary hard disk.  Total cost is a couple external hard drives every couple years, or about $200-300/yr.  Not bad.

 As a tech, Ive ran into a few external drives in which a component failed inside the device,
causing improper voltages going to the drive... resulting in it being useless.  Spins up, but
wont read/write/detect.

 You can test this easily with a multimeter.  First at the power supply... and if that passes,
then at the rear pins of the drives power connector.

 There is no such Guarantee.  Partly due to the fact that the tech has Not been in place for 25yrs.
Also, Ive read reports of people reading and writing constantly on purpose, killed flash drives in
less than a day of time.  Of course, there isnt much reason to argue about it - as flash drives of
any real size will cost a Lot more than other means.

 I hadnt opened the CDRs I had bought over 7yrs ago, in room temperate, in a room with
blocked off windows (no sunlight, only indoor lighting).   When I finally did open them,
the coating flake off on my fingers from the lightest touch.

 The Discs they use to make your CDs and DVDs for commercial sales... and not the same as
the ones they sell at the stores for PC burners.  A commercial DVD probably will last a lifetime -
unless you scratch it badly.  Not the same for consumer burnable discs.

Hmmm....

Monmotha v. X.  I'm putting all my money on Monmotha being right and being able to prove it unlike our resident know-it-all.  X never proves it.  He just blusters and tells people if they don't like it not to read it and that the masses here want to keep him quiet.  Seriously, can you document what you say AND have it be from a credible source?

Monmotha is a tremendous help to others here with (seemingly) obscure technical data that's always on point.  X just likes to talk about how he worked in an arcade so he knows everything about it. Funny how being a change boy makes a genius even smarter. Now he's a hard drive tech too!

 I was a change guy for only a few weeks.  Then I became the store
manager for 3 years.  Which involves well more than counting money...
and included teaching myself how to fix 42 arcade & mechanical redemption
games.

 As for SSD last-ability, and almost all last-ability that is listed by MFGs,
are general specs that are guesstimates based on percentage of usage,
ideal conditions, and short range tests.  Rarely ever long range test,
(how could a company test a drive for 25yrs before its sale?!), or pure
factual results.

Monmotha is a tremendous help to others here

 In case you didnt notice, I gave plenty of helpful advice throughout my
many years here..  Including in this very Thread!, for which me and
your buddy agree on HD backup as the better solution.

 Instead of throwing your hate for me around... maybe you should
concern yourself with much more grown up things in life.  You will live
longer, and happier that way.

 :blah:  X, I don't hate you.  You aren't worth time or effort like that.  I just don't think you're the god that you claim to be. 

My suggestion is both physical and cloud storage.  With Google docs taking any type of file now, dropbox being a great asset, and other sites that can take multiple gigs of pictures with no fees, there's no reason not to use some of these services.   Granted, no for sensitive information, but for general off-site storage, it's a free, relatively safe and secure path to choose.

It's not really a fair challenge cos you are limiting him to logic and not evidence, when the obvious method of proof here would be citation rather than argument.   ;D
