Will a standard subwoofer magnet wreck havok on my PC?

Btw - One thing that hasnt been brought up is vibration damage to hard disks.

 If a drive isnt spinning... it can take a bit of vibration without harm... but at 7200 rpms... a subwoofers thump will end up damaging the internal heads inside the drive.   I believe these heads are near microscopic at the ends... and are the reason for most drive failures.
 
 This may not seem apparent right away... but youll probably reduce the drive life expectancy by 1/2 or more.

  My thought is that youd want to make a bungee cord type suspention system.  Something that will hang the drive in midair and keep in from getting affected from vibrations.

  Also... about the magnetic stuff...  Id add a thick board about 1" above the magnet to help absorb the feilds.  

  Ohh - and dont forget to point a strong fan to  blow air across the hard drives to keep them cool.   Heat expands the metal - which causes problems in allignments,  which destroys the drives.  General cooling isnt enuff in my opinion.. and I speak from a previous 3 drives failures before discovering why.  After installing fans in front of all my drives... they have lasted 3+ yrs so far... (i run 4 drives in my pc - 2 are backups)





Trimoor:

Unless the subwoofer is attatched to the computer case, it will do nothing to harm the drives.  Subwoofers just aren't that powerful.

If you try using bungee cords, more likely it will end up oscillating, which will cause much more damage than a subwoofer.

Sorry, but wood will do nothing to absorb magnetic fields.  The proper material to use is ferrite, but it could be hard to find and be expensive.

Cooling the drives is always a good idea.  Whatever you do though, don't take the case off to aid in cooling.  This reduces the airflow, actually causing it to be warmer than with it on.

to add to the magnet moving problem in physics. dont forget its all relative. the hard drive is moving in that magnetic field. as well, the physics you talk of is mostly to do with generating a current. if the speaker were close enough to the hd, then the fields might (theoretically) align the magnetic information on the drive in the same manner, moving or not. a thought experiment here. put a floppy disk with info on it directly on the speaker magnet. leave it a while. its not moving, but you can imagine that youve probably ruined the info...

still i reckon youd be able to have the hard drive safely away from the speaker regardless. the best insulation is distance
