Re: DRIVER NEEDED: Western Digital WD1600XMS-00 (Windows XP Professional) [USB]
USB hard drives do not require any driver other than what is provided natively by the OS. If the drive is not being detected and installed automatically by the system during bootup, then you need to go to Computer Management, click on the disk and choose initialize in order for windows to recognize it.
Also, be sure to go into Device Manager and see that the USB port(s) are working properly.
The notification should say "Found New Hardware" then within a few seconds it should say "this device is ready to use".
Has it ever worked?
