Disclaimer: The following information was collected & publicised based on strenuous research of Toshiba’s disk drive identification formats from models produced prior to 1996. This table does not reflect current Toshiba model identification, nor drives produced past 1996 with this model layout. The table below is not supported by any official Toshiba documentation, as this is not available to the public. As it stands, some of the information below may be slightly inaccurate without full confirmation being available.
