Thanks!! I joined this forum specifically to thank all of the wonderful, friendly people here for sharing this information. The Device Manager fix worked for me. I’m using 32 bit WinXP SP3 (Vista 64 bit basic doesn’t agree with my gaming). I just bought 2 Super Talent 128 GB solid state drives for my current beast and installed them in a Raid 0 configuration (wow!). I used the 15 day free trial edition of Acronis True Image to move the OS from my old WD 320GB HD. It worked fine. My first attempt at using MS Backup resulted in this error, and short of reinstalling the OS from scratch I came across this thread. SSD’s are becoming more popular as the price drops, and many people are going to have to decide how to XFR their OS to the new faster drive. I for one would recommend using Acronis True Image with caution. Thanks again to all!!
