All of a sudden when I open a folder it says disk not formatted

[Johnx64]

I have 1 hard drive its formatted into two partitions. C: & D: . I have my music on d:\stuff\mp3z and was listening to it fine last night but today when I try to play something everytime I open that folder it tells me the disk in drive d: is not formatted. Every other directory on that hard drive works just not my mp3 folder! Everything is upto date avg\windows. When I right click the folder it takes 5seconds for the drop down menu to load and view properties it takes 10 seconds to load and tell me 0 bytes 0 folders when it should be around 15gb. I've restarted a couple times and that didn't help.


What to do?

Backup everything that is important to you now! Your disk drive is probably about to crash
