TOSHIBA DT01ACA300 is a hard drive model created by Toshiba. It is a 3.5" 3 TB 7,200 RPM CMR hard drive, and is a rebadged unreleased Hitachi Deskstar drive, namely the Hitachi HDS723030BLE640, which early models identified to host as.
This drive no longer has direct competitors, but it formerly competed with the ST3000DM001-1CH166/-1ER166/-9YN166 and ST3000DM008-2DM166. This model also has a retail rebadge as the TOSHIBA HDWD130.
History
Following an initial wave of 1-platter drives, the DT01ACA300 was part of an initial wave of multi-platter drives based on the 2- and 3-platter Hitachi HDA, released in August 2012.[1]
Prior to approximately December 2012, drives of this model identify using the Hitachi HDS723030BLE640 name, despite the DT01ACA300 model number being printed on the label.[2] These early batches also contained Hitachi-specific parameters such as MLC and P/N, which were removed from later batches, leaving only one identifier code, the DRIVE REV. They also contained two serial numbers; the Hitachi-assigned one, which followed Hitachi's normal convention, and a "T S/N", which was the Hitachi serial number with the first three letters replaced with a Toshiba-style date of manufacture code, and four letters added to the end, one followed by three more. Although modern DT01ACA300s only have one visible serial number on the top label, the normal Hitachi-style serial number is still present on the front label. The Toshiba serial number replaces the first three letters with the same Toshiba-style date code, as well as adding an S to the end, corresponding to the location of manufacture, China.

Trivia
- The DT01ACA300, like most Hitachi desktop drive firmware (dating back all the way to the IBM Deathstar family), has a bugged Power-off Retract Count counter; it always matches Load/Unload Cycle Count, even if the hard drive has always been powered down normally. It can sometimes exceed Power Cycle Count and Start-Stop Count, which is also illogical, since there can never be more power-off retracts than there are power cycles. The SMR 3-platter variant based on the same HDA, TOSHIBA DT02ABA600, does not exhibit this issue due to it running native Toshiba firmware; the Power-off Retract Count correctly increments independently from Load/Unload Cycle Count.
- On drives that have Hitachi logos and label layout, the KCC Authorization Number is listed as KCC-REM-HTB-DS7SAE302 using Hitachi's KCC manufacturer code. Purely Toshiba logo drives instead use the Toshiba KCC Authorization Number code listed in the infobox.
