i was getting a explorer.exe error every other time i tried to go into my computer or c: . it would say explorer.exe has generated errors and will be restarted. so i tried reinstalling win2k as an upgrade and now i get up to the startup screen with the white progress bar....and then i get a win2k blue screen stop message referring to pfc.sys saying it was not handled. tried rebooting into safe mode...still no good...i have so much data on this drive...please someone tell me its salvagable...
