I recently installed a new Seagate 4T HD. My older WD drives were failing and I moved their contents to the new one. It was working fine. Last night it suddenly became unavailable and windows says it needs a reformat before it can be used. It is Simple, Basic, Raw. Healthy (primary partition). It says
Y is not assessable . The volume does not contain an recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted. How would those drivers disappear and what can I do to restore them without losing my data?
Here is more info. When it happened I was using the Seagate Disc wizard to copy a damaged disc to another good disc so that I could restore the data on it safely. This did not involve the current problem disc at all. When the cloning was complete the 4T disc was still running. The Discwizzard restarted my PC and the 4t HD was not working when I checked it.
I have scanned for viruses with AVG and Malwarebites.
It passes Seatools short test.
The OS is Windows 7 64
Any suggestions will be appreciated. I am not familiar with the more pro grade disc tools but if I knew one would work I would learn to use it.
