Ask me if you want to know how to format your Xbox HD for your PC, I'll give you more details if you want. First, you can't just format it right away, the drive is 'locked' when it comes out of the Xbox. There are a few ways to unlock it so you can use it your PC, but there are a couple things I would need to know first -
1. Do you still have the Xbox it came from? 2. Is the Xbox 'modded'? If so, it's really a piece of cake....if not- 3. Do you have a backup of the eeprom.bin file from the Xbox? This is crucial...otherwise you'll either have to buy or build a device to read the eeprom.bin file. (you need the eeprom to unlock the drive)
