I had a pc with XP pro on it. I moved it to another cubicle and then DEAD!!! I check BIOS, and it sees it. When I boot I get non-system disk. I have since taken the HDD and put in another machine and took the CD-ROM out and attached via IDE 1 and left the original HDD on IDE 0. It saw the second HDD in BIOS and again in Windows, no second drive. I have tried locating it via Ghost in PC-DOS and again it didn't see it. My last resort is putting it in a freezer bag and it is now in the freezer and will sit there for a couple of hours and I will try again. Any help would be greatly appreciated. Thanks.
