Hi there,
I've got a 400Gb external drive which suddenly stopped responding. I switched it off and then on at which point it started making an odd 'singing' sound and windows could no longer see it. Plugged it into a UNIX box and the disk stopped singing, the OS could see it but couldn't initialise it. Moved back to a Win 8 box and now it's wanting to initialise as a 2Tb disk. As is always the case this disk contains quite a bit of important data and I last backed up 2 weeks ago. Does anyone have any ideas on how I might convince it to come back or software I might try. Many thanks!

Generally, mechanical oddity noises from a hdd means its finished. Your best bet I here is to slave it on a linux machine and scan the drive sector by sector to see whats accessible. I am no expert in data recovery, so you will have to see if anybody else has a bright idea short of paying recovery experts to try swapping the disk plates out into another drive.

This is pretty unlikely. enclosures don't just stop working. hard drives on the other hand, do. also, enclosures wouldn't make singing noises. Hard drives would.
 
I respectfully disagree with you. Sure external enclosures fail. Anything electrical or mechanical can quit the moment it malfunctions. A quick search will turn up many an external hard disk user who found the enclosure to be faulty.

On the other hand, what's there to lose? The thing's not working anyway.

"Singing" noises are rather subjective in my opinion. How do we know the drive is still being fed sufficient power from the enclosure or it's power adapter, and is thus spinning up and down, or parking the heads repeatedly. I haven't heard the singing, so I can only speculate on any sounds being heard.
