So I'm at it again, I suck. I've got a list this time - I added a slave drive, and it randomly stopped working. I didn't unplug anything... it just stopped. Here's my thoughts, I have the slave right next to the master (about an inch between them) did the slave overheat? Because I plugged in another, smaller, drive and it works. - When I turn the computer off (Windows), it starts up again. Then I hold down the power button to turn it off... it starts up again. Eventually I just have to unplug it. There is probably more... but I forget it.
