It may be like hunting a mouse with a shotgun but here is a trick I used with my system in school. I put a second drive in it and used Ghost to simply clone my drive. I installed another power switch in the back to control power to the drive. My room mate and boy friend were always messing with my system. If you use an adaptec SCSI card and SCSI drives it is much easier to create a cloned drive to use as a recovery source or even to boot too when your in a crunch. You can use the SCSI controller to point to the drive you want to use. On my work system I simply use several AT commands to clone my drive. The *.bkf file has not been good at capturing the system state in an ADS environment in my opinion.

Sorry if I was too wordy but good luck to you.
