|Long shot... wrap the drive in paper towel; place isn plastic bag (e.g a sandwich bag); place i the fridge (bottom shelf) for about an hour... Some suggest the freezer is OK and again about half an hour. (I've only ever used the fridge area...)|
Remove drive in bag from wherever; open bag and loosen paper towel a little - but do not remove it entirely. Let the bag and contents breath as it were for a few minutes - 5 maybe 10 at most. Remove drive from bag and paper towel. Using a suitable usb adapter (a typical cable system is ideal - rather than proper enclosure) connect to a working computer (via usb of course). There is "very slight chance that the drive may resurrect "long enuff" for you to access contents;and copy to DVD and/or the hard drive of the computer to which it's attached.
If it does it will do so for a wee while and then possibly go down again.. If so repeat the cooling process as above; and then reconnect etc. to the working computer and see if you can access/recover/copy more data? There will come time when it will not resurrect.
Ideally do the whole recovering data process in a cooler rather than warmer environment. Idea is to keep the drive "cool-cold" as long as possible. Running/accessing the drive will generate heat, the drive will warm up - and that may cause it to fail again; at which point you repeat the cooling process as above.
This is usually effective with drives that have started to click etc.; and even "stuck/jammed/failed to spin up... The cooling of course increases the clearances of the moving parts and thus allows a possibly "stuck" drive to spin up for a wee while at least.
You have nothing to lose by trying it; so I suggest you give it a go?
The paper towel is absorb any moisture/condensation that may otherwise land on the drive assembly when it goes into the fridge/freezer, and when you remove the bag and drive from the fridge/freezer and let it breath a little. When you connect the drive to the working computer just double check there is no moisture on the electronics side (if exposed); and if there is mop up/dab off with a tissue?
