I received a new Western Digital 500GB hard drive yesterday. I plugged it all in then went about partitioning and formatting the drive. Once it had finished I started copying some photos over to one of the partitions. Shortly after the copy started it stopped and said something about not having a device connected. The new hard drive had disappeared under device manager, disk manager, My Computer and whatever else I tried to find it with. I rebooted and it showed up fine until I tried copying to it again. It disappeared again.
I ran the Data Lifeguard Tools program from the Western Digital website which said about not having the right settings for large hard drives when I started the program. It changed some settings then when I rebooted, Windows wouldn't finish loading. It has the bars scrolling along the bottom but then the screen goes blank.
If I take the power cable off the new drive I can boot into Windows normally. I've checked the cables are all secure. My motherboard is a Gigabyte 965p DS3 rev.1.0 BIOS F12. I'm sure the sata cable is in the right socket (Orange). I've reset the CMOS both by going into the settings and taking the battery out.
I've spent a while on Google and a few computing forums but can't find anyone who found an answer to anything similar. Most of them just say "It's ok now, I fixed it."
