Over the last 4-6 weeks, I randomly get a message saying some file (not always the same) is corrupt and that I need to sign in as administrator and reinstall blah-blah. I then run CHKDSK and everything is fine. Earlier on, during boot, the would CHKDSK run through all my files occasionally. I built this computer over 2 years ago with an OCZ Revo drive (128mb) PCI express as my boot drive. No bad sectors have been found. Is this SSD trying to crash or is there something else going on. Running Windows 7, I have a 1TB drive use for other programs. The OCZ is about 1/2 full.
