I took an External Hard Drive apart to get a hold of just the hard drive itself. The hard drive is a SATA drive, I connected the drive into my computer along with my original hard drive which is to a SATA drive. When booting up the computer I get the following error "Verifying DMI POOL DATA DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER" but when I disconnect the drive I boot fine into Windows XP. I am in AHCI Mode, I tried switching back to IDE and I still get the following error message. Any recommendations on how to fix the problem?
