Can anyone point me to a third party chkdsk or scandisk type of software for Windows XP? I have a drive that stores data fine, but it can't be fully formatted, and must be quick formatted. I also can't boot from it. Any OS installed on it will install fine, but refuse to boot with no error messages. I'm guessing theres a problem at the beginning of the drive ... but chkdsk also chokes and hangs while checking the drive.
