New External USB Hardrive not showing

[MollyK63]

I am helping a friend upgrade his Windows XP box. I bought a brand new Passport external drive, plugged it in, computer recognized it and installed drivers. When I go to my computer, it does not show it. If I go in and start a backup of entire computer, it does not show this drive in the list. I can see it in the Device Manager and plugging in any other USB flash drives show in My Computer. I have uninstalled and reinstalled drivers. What the heck! This may sound crazy but is the computer somehow setup to prevent any sort of backup or cloning of drive?

Click Start, and then click Control Panel. Click Performance and Maintenance, click Administrative Tools, then double-click Computer Management, double-click Storage, finally double-click Disk Management.

Does it show up in here?

If it does just follow these instructions - http://support.microsoft.com/kb/308424
