Alright, I pulled out the drive caddy, put the second HD straight in, reformatted it as basic, and started copying the data back onto it. It's been two hours and it's still going, I figure at about 10 GB / hr. Does that seem right for IDE? (For comparison, just yesterday at work, I moved a whole terabyte between a server and eSATA devices in less time.) Both hard drives have the jumper on "cable select". Could that have something to do with it?
