I've been using my laptop with Windows 7 with an USB to SATA adapter to read files from an XP hard drive. When I put the drive back in the XP tower, XP will not boot anymore and gives me a 7B error. Does Windows 7 alter the files on the XP drive when it reads it? Just curious if anyone else has encountered this....
