WELL I DECIDED TO REGISTER AS I MIGHT BE ABLE TO HELP...IF THE HARD DRIVE APPEARS IN THE DEVICE MANAGER WITHOUT ERROR, IS IT MOUNTED WITH A DRIVE POINT IN "COMPUTER MANAGEMENT" BECAUSE I HAD THE SAME PROBLEM SETTING UP DRIVES BEFORE.
YOU CAN TRY GOING TO START-CONTROL PANEL-ADMINISTRATIVE TOOLS-
OPEN COMPUTER MANAGEMENT
CLICK DISK MANAGEMENT ON LEFT HAND SIDE
SEE IF YOU SEE THE HARD DRIVE THAT DOESNT APPEAR IN MY COMPUTER
RIGHT CLICK ON IT WHERE I WOULD ASSUME DISK 1 FREESPACE WHICH WILL PROBILITY SAYS HEALTHY, CHANGE DRIVE LETTERS AND PATHS, AND ADD A NEW MOUNT POINT.
HOPE THAT HELPS.
