Hi everybody. vista keeps telling me constantly that my disk structure is corrupt and that i need to run chkdsk. This happens whenever i want to download something and also when i'm just working. I think it was caused by the chkdsk vista ran yesterday and since then i've had problems. PLZ help. Thankyou. Also, if there is any software that can diagnose and correct drive errors i would be very grateful. ps:I can't run chkdsk because whenever i launch it using run it comes and disappears in less than a second.
