Both drives do not post. Actually, when I found out that the first one crashed, it tried loading windows from the backup drive even though it was not on the drive. Because this drive still posted, I thought my new hard drive was the problem. This is when I gave both drives to my friend so could take it into his work and do some data recovery by putting the data from the new drive onto my backup drive. It was a while since I did my last backup, so I needed data off of the new hard drive. He insisted that because the drive was so new, data recovery at his work would not be a problem. Two days later, he failed with the data recovery. This is when I decided load windows on my backup drive. I also know that the drive that crashed is still under warranty from Seagate, so that is not lost. But anyways, when I got the drives back from him, I popped the windows cd in drive and the setup started. Once it got to the point where it asked about partitioning, it said unknown drive and then when I arrowed down, the blue screen of death popped up. I did not think this drive would fail too. Once I turned my computer off and back on again, the backup drive did not post. I am unsure if it posted before or I popped the cd in the first time because the drive worked when I gave it to my friend. This leads me to believe that something with the hardware is frying the drives. So I guess I partially lied when I said it was an hour later. It was a lot longer in real time (a couple days), but it was only an hour later if you only count the time that my computer was actually on. Now I might consider sending the drive to you Bullox. Unfortunately, I don't have any of the drives on me right now. I just gave them to my dad who is going to have someone at his work's IT department look at it. If he fails, I was going to send it into Seagate and get the replacement drive. But I might send it your way, if you want to try to do something to the drive first. I am in no hurry to send it into seagate because it is under warranty until 2013. Then after you sucessfully recover all of my data (being optamistic), you can send that drive into seagate and have them send the replacement to me. Also, If anyone wants to get rid of an old hard drive, my computer is hungry for another one................................
