Thanks for the information. My Server is co-located, so It will be hard to test before I try to implement the change. I do have a DAT Tape drive in the box, but It is a highly customized webserver, and I would hate to rely on the tape for restoring the system partition/files. I could always image the drive to a spare before trying anything, but I need to know what program to use. I use Ghost exclusively, and I have seen some people say that Ghost does not do a good job on non-win32 formatted/partitioned drives. What program should I use?
