You could well be right about AdAware causing the problem - I am presently running AdAware 11 and I have the same drive status warning (now disabled as no problem found using chkdsk /spotfix).
I was hoping that this would be the easy solution - but it was not. I uninstalled AdAware, problem persists.
Worse - when I upgraded from Windows 8 to 8.1, the false error doubled - now I get TWO of them and have to wait EVERY TIME while booting for the laptop to perform the check. The problem went from sporadic to constant.
The easy thing would have been if Microsoft was not stingy in providing DVDs with the purchase of the OS instead of this BS they do with Dell and other manufacturers...
