My sata drive has disk errors 0f00:0244 and I'm unable to boot up into windows XP. I attached a backup drive with Windows XP via USB and make that my default drive. However, when I boot up it is not recognizing this drive at all.
Windows XP cannot be booted from an external drive. You will have to connect it to an internal SATA port, and then deal with any issues related to different drivers that may prevent Windows from booting without some effort.
