Chris:
I suggest reformatting the drive to get rid of whatever is on there now. Several ways to do this, depending on what tools you have available.
A] If the Maxtor came with a CD and installation utilities (MAXBlast), do a low-level format ("Zero Fill Drive" under the Utilities Menu -- you don't need to do a FULL version, the QUICK version is sufficient to wipe out the partition table (the three drives you're seeing in Windows). (Boot any PC with the MAXBlast CD. MAKE SURE TO SELECT THE CORRECT DISK DRIVE.)
-- OR --
B] Attach the drive to a Windows PC (external is ok) and use Start/ControlPanel/AdministrativeTools/ComputerManagement/DiskManagement. RightClick on each of the three partitions and choose "Delete Partition" (MAKE SURE YOU DON'T ACCIDENTALLY SELECT partitions from the wrong disk drive.)
There are other methods ... write back with your progress or if you need more help. But after doing above you should be able to have NASLite+ configure the drive properly.
