I tried going into the properties to see if I could change anything and there's no option there showing that a change can be made. I tried doing a system restore, but nothing happened; I was having the same problem with my USB and then I formatted it and it went back to normal. I don't want to format either drives, there's too much info on there that my bf needs.
I think I may know what caused the problem, his anti-virus detected a worm "fun.xls.exe" on my USB and on his external hard drive and I had it moved to the virus vault. A warning showed up saying if this was moved it would cause the system to crash...I moved it anyway and nothing really happed except for the problem I just stated. Please help & thanks!
