Ok, the tedster's got one... I got a old hdd I cloned to a new hdd in a laptop. After cloning the data to the new drive, I attempted to clone data BACK to the old hard drive. In the middle of this, I realized my error. The new drive is fine and has worked for a while. The old drive I attempted to use as a usb external drive. Now every time I plug it in on a usb port on ANY computer, I get a BSOD, and the computer crashes. I really don't want to reinstall the drive back into my laptop and format it from windows cd. is there a way to format it via usb without crashing windows? I am sure the boot sector is corrupted causing the errors.
