I recently used my WD external hard drive (640 gig for those who want to know) on a computer with Windows7. I recently had to re-install WindowsXP on my home computer due to a cousin reformatting my hard drive. Now for the crux, my external is only listed as an unknown usb device. It is not a "assign it a drive letter" problem because it does not even show up in disk manager. it is not a "delete 1384" problem either because I never had it in the first place, it not listed on my connections. Please help if you can.
I also have this problem.
i have a 320GB WD external disk with all of my backup on it.
it shows up as "unknown USB device" and doesn't get a drive letter assigned. I cannot find it in administrative tasks either.
The information on this disk is vital for me.
