Start> Right click on 'my computer'> manage> 'disk management' under the 'storage' branch (left pane)> in the right, lower pane, right click on the drive you want to change> change drive letter and paths.
It should be there. Try this path: Start> control panel> administrative tools> computer management> highlight 'disk management' on the left - on the right you should see your drives in the lower section - right click on the one you want to change and select 'change drive letter and paths.' Look at the attachment for guidance.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
