I have an XP machine (SP3, all updates) on my home network (workgroup) I plan to use as a backup box. I just bought a 3TB WD MyBook external USB drive as the backup target drive (shared, mapped network drive).
Something concerned me when I opened the box: the WD has a power switch on it (may be the problem???).
At any rate, when I reboot this machine with the WD attached, it hangs in BIOS. The moment I unplug the new WD USB drive, boot continues normally. If I plug it back in before exiting BIOS, it hangs again. If I wait until after seeing the XP startup screen, it continues to boot normally.
Otherwise, the drive also performs normally, no errors or dirty chkdsk bit. USB is not involved in boot sequence.
What do I do about this?
