chkdsk, with or without the /f parameter, will no longer run. My os is XP Home, virus-free, I've done all the usual commands and got confirmation that it will run next time the computer starts up, but nothing happens, it just loads Windows each time. Any suggestions?
Haven't yet tried in Safe Mode, but yes Stylehurst, I do have ZoneAlarm 5 installed - recently upgraded from v.4.5. If that is the problem, it's annoying, cos I assume the later version is more effective. Does the problem apply to ZA in the free version, as well as Pro?
