On my home PC running XP, I have two hard drives. Nothing special, EIDE, set up as master and slave. A 12 GB and an 80 GB. Both drives work perfectly fine in normal operation. The problem I have is that I can not run defrag on the slave drive. As soon as I press the "anylize" or "Defrag" buttons, the blue screen of death pops up for a split second and the machine immediately reboots. I have checked and double checked the drive's jumper settings and cable hook up. I have DL'd a quick monitor program to check the drive's health from Western Digital and it says everything's peachy. Has anyone ever had this problem? Any pointers (other than ditching Windows)? Thanks.
