I was defragging my C drive with Diskkeeper Software, went out for awhile, came back to find the hard drive light on, blank screen. Rebooted and a message came up unknown format, replaced the hard drive and was able to read the D partition of the bad drive and recover those files PTL! Has anyone had this problem with Diskkeeper? The Drive was a Maxtor 40 gig, about 2 years old. Thanks for any responce, popi
