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 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.
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.
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.
Quality CD media stored in a controlled environment (dark, room temp, low but non-zero humidiity) should last 10 years or more.
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.
All these specs assume you have a quality burner, which most people don't. For your cheapo $35 CD/DVD burner, quarter the lifetimes.
Heh. Thats Scammer Info IMOP. Prove it with any form of Logic.
