Hi John: I'm not sure if it's related to WIN XP no change, SP1 or SP2, but if WIN XP "sees" more than one copy of itself it does bad things to your hard drives. There's a Symantec web page describing how to use Ghost 2003 (running under DOS, not windows) so that you do NOT have both drives connected to the computer and allow WIN XP to boot. Note that "Ghost" has two modes. In one you make an "Image" of your drive that is not bootable and in the other you "Clone" or disk-to-disk copy the drive. I believe that the only trustworthy backup is to clone the drive and then use the clone as your main drive. But it's a hassle to swap hard drives since WIN XP sees the drive serial numbers and does not like the new drive. A close friend was using RAID just for backup and a few months ago had a hard drive failure. Since he makes heavy use of his computer for his business this was not a good thing. He had tried a data recovery service with no luck. I told him about http://www.drivesavers.com/ and they recovered his drive for $ 4,500. He is now using an on line backup service since he is lucky enough to have a high speed internet connection.
