I figured I'd post this here instead of software because I may need to reformat / reinstall to get this computer working again. An older 333 AMD K6-2 now gives me the error when I attempt to boot: (something along the lines of ) error reading drive C, Registry is corrupt. Retry, Abort, Ignore. The bootup to Win98 goes no further. I've tried the quick version of scandisk from dos but it doesn't fix the problem. Will the detailed scandisk fix the problem? I may try that. As a side note, this computer had been locking up mid-day for some reason I've not been able to determine, requiring a hard power down to get it to restart. In that process over several restarts I'm assuming the hard drive became corrupt, that is if the lockup problem wasn't already due to a corrupt hard drive. Any way to restore a registry before I go to more desperate measures? Would you suggest reformating then reinstalling? How do I make sure the bad disk sectors aren't reused after a format?
