Hi, I ran the wdidle3 utility from DOS for this drive and 2 other WDs.
The others are working fine but this one won’t show up in Windows.
It shows up fine in BIOS, showing capacity and everything, but in Windows 7 under Disk Management it has Dynamic, next line, Invalid under it.
It appears when I go into Properties/Hardware but when I click to Populate under Volumes for it, it says Volume information for thjis disk cannot be found.
EDIT - It appears that the data is definitely still there. Running data recovery software, it is all accessible and as far as I can see recoverable (tested it with a couple of files), but not directly through Windows Explorer.
