I've used this tool many times to check/test if a drive is defective without adding any more stress to it:

If the drive is in bad shape but has replaced all the bad sectors (that exist at that moment) with spares the chkdsk will pass (not that we seem to be looking at the results.), but the drive will still be defective, or if it is in really bad shape it may never finish or the drive might just stop working. Defragmenting a defective hard drive would be even worse for a bad hard drive. Vista's defragmenter was unusually slow except when their was nothing to do (maybe a long defrag happened when you did not notice before the quick defrags).Īlso I'm not so sure about putting a computer one suspects has a defective hard drive through a long and intensive "chkdsk c: /r" (non-interruptible).
