I got surprised yesterday when I received my WD 500GB SE16 Sata2 plugged in my ASUS P4P800-Dx (which only supports Sata1) and The BIOS recognize the drive right away, but not Windows, I've prepared the HDD using the WD lifeguard tools and after that it seem impossible to access the HDD. I've tried Partition magic and no luck recognizing the drive on XP. Could it be an DOA?something about compatibility with my MOBO? or Corrupted Windows? (I've been having issues with windows before the HD) All input will be appreciated, Thanks!
