TOSHIBA DT01ACA100
From Computing Classics Wiki
TOSHIBA DT01ACA100 is a hard drive model created by Toshiba. It is based on the Hitachi HDS721010DLE630, with Toshiba labelling and drive revision numbering. It, along with the TOSHIBA DT01ACA025, TOSHIBA DT01ACA032 and TOSHIBA DT01ACA050, is the first consumer-targeted 3.5" hard drive model to be released by Toshiba.
Competing drives include the various incarnations of the WDC WD10EZEX, ST1000DM003 and ST1000DM010-2EP102/ST1000DM010-2DM162.

Trivia
- This hard drive, 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, which is also illogical. The SMR 1-platter variant based on the same HDA, TOSHIBA DT02ABA200, does not exhibit this issue due to it running native Toshiba firmware; the Power-off Retract Count increments independently from Load/Unload Cycle Count.
