E-Sata isn't a removable device, so you may have to add the disk using XP disk management
Right-click on 'My Computer' select 'Manage'
Click on 'Disk Management'
Click 'Action' then 'Rescan all disks'
Pretty sure the method is similar for Vista.
thanks for your response Stuart,
1st, I tried contacting HP support which is a piece of **** b/c they make you pay for support : /
I right clicked on my computer and clicked manage, but I don't see "rescan all disks" under 'action'. The only options I see are:
connect to another computer
So instead, I clicked on Device Manger, right clicked Disk drives and chose 'Scan for hardware changes' but this didn't make my hard drive show up either : /
Did I do something wrong ?
