The serial numbers on a Quantum Bigfoot ATA hard drive can be found on a bar code label affixed to the bottom of the drive (opposite side from the green PC board). A “SN” will prefix the serial number. The Quantum serial number is a 12 digit number that immediately follows the “SN” prefix. In some cases the 12-digit serial number may be followed by a letter (this letter is not part of the serial number).
To use the table below: The bolded values in the model and capacity code columns are the alpha-numeric characters found on the disk drive’s TLA label. The TLA (Top Level Assembly) number is located on a the bar-code label affixed to either the drive’s top cover or on the drive’s interface connector. See the diagram below for examples and locations.
On Quantum hard drives, the terms “TLA“, “GTLA“, and “Part Number” all refer to the same hard drive model indicator and should be considered interchangeable.
By referring to the drive’s TLA label and then scrolling through the table below, you should be able to identify your drive’s product family and its capacity.
Interface values:
Capacities are listed in Megabytes (MB) or Gigabytes (GB) as noted.
Early versions of the Atlas and Capella disk drives did not carry the complete TLA number scheme. Please refer to the drive cover label if you suspect your that you may have either of these products. The drive label does contain the product model number displayed in the above table.
DSP drives are not included in this table. DSP series drives were manufactured by Digital and contain Digital part number schemes.
