When chkdsk performs an autocheck, it allows you to cancel the check by pressing a key within 10 seconds. It takes many attempts for it to acknowledge the key press, though. Am I the only one experiencing this? Usually, I can trigger it by 6 seconds (it starts at 10), but just now I couldn't stop it at all. I rebooted and attempted 4 times. Nothing. I know my keyboard is fine not only because I'm typing to you now, but because I always hit F8 to manually choose my boot hard drive.
I recall it being the same in Windows XP, and expected to be fixed by Windows 7.
If you're wondering why I don't just wait it out. 1) waste of time. 2) I've actually had a drive wiped by either chkdsk
or a faulty NTFS driver in Hackintosh, but I don't know which it was, and prefer to avoid it period.
