I have 2 Dell desktop Dimension computers, an 8250 & a 4100. The 8250 has a slave drive that is going bad. The HD on the 4100 has a ton of data on it that I would like to save. Since the 8250 is already configured for a slave drive, can I unplug the old one that's going bad and replace it with the HD from the 4100? All drives have XP and the same type of wiring harness from what I can see.
