Another option is to use SpinRite, which I use whenever I run into a hard disk problem that ScanDisk can't resolve. It costs $89, and you can buy it by ordering it via phone (1-800-736-0637), and then downloading it (97K). You can check it out at
Microsoft recommends using ScanDisk for "routine maintenance", but when you run into something that's not routine, they recommend buying a "third-party utility package". In other words, they're admitting that ScanDisk is just a first line of attack when dealing with drive problems. (I read the above recommendation in one of
KnowledgeBase articles, and, dummy that I am, didn't print it out, and now I can't find it again!)
No, I have no vested interest in
or any of the products found there. I'm just a techie guy who was frustrated by hard drive problems which ScanDisk could not fix, just as you are. I have used it on dozens of systems, so my cost per system is just a few dollars. It's one utility that I always have in my software "toolbox". And I have yet to encounter a hard drive that it couldn't "fix" for me (including saving the data that was located on bad clusters). I've "resurrected" drives that other techs had dismissed as being "hopelessly trashed".
