[Blackpool] HDD data recovery

I think Boards of Canada released the sounds your drive makes as a single.

Considered swapping the hard disk board?  Have you totally eliminated the board as the culprit?  I'd be surprised if the WD DLG diagnosis tool can't tell you definitively if it's the board or the moving bits just by chatting to the board.

...All I got.


I have a life of file detritus on a 4x WD Red RAID, don't be shaking my faith in WD! 

Regards
Arthur

The permissions issue would resolve itself by restarting the server. Eventually, the HDD wouldn't show at all. However, when I plugged it in to a different computer, it worked fine. I thought this could then be an issue with the server (an ancient laptop) and its USB ports (even though the WD Elements has its own power supply). I tried a USB Y-cable with the HDD's SS-USB cable and once again it worked. However, after a week or so, videos being streamed from the server would fail and the drive stopped being recognised, so it looked like it might not be a power issue.

All it does now is spin up and spin down several times before giving up (using the Elements interface) or just continually spins up and spins down (using an alternative external interface); with the latter, if it's left on for an extended period it can eventually spin up and stay spinning for 20-30 seconds before spinning down. Other than some occasional light clicks at the peak of it spinning up, there is none of the normal clicking that I might expect to hear from it. After a short while, I'll get a dialogue box telling me "The disk you inserted was not readable by this computer", which I assume means something is recognisable.

But not for a total mechanical issue as you said.
