There are currently two different labels used on Atlas 10K III SCSI drives. One label identifies the drive as a Quantum® drive and the other label identifies the drive as a Maxtor drive. The Quantum® label was used on all drives manufactured as Ultra 160 (U160) drives and are fully supported by Seagate. All Ultra 320 (U320) versions of the Atlas 10K III will have a "320" printed on the Maxtor label. Please see the following examples:
How To Determine Your Atlas 10K III Model Number:
The GTLA (Global Top Level Assembly) is the part number used by our factory and is different from the model number used by our resellers and distributors (the model number will not be printed on the drive). Based on this, please use the following table to determine your drive's model number by using the first 5 digits of its GTLA number (to locate the GTLA number on your drive please reference the corresponding label example from above).
