Hitachi HDS721050CLA662 was a hard drive model created by Hitachi and later HGST. Part of the Deskstar 7K1000.C family, it succeeds the previous Hitachi HDS721050CLA362, upgrading to SATA 3.0 whilst keeping other basic specifications the same.[1] Thus, it is a 500 GB 7,200 RPM 3.5" hard drive model using one 500 GB platter. It was succeeded by the Hitachi HDS721050DLE630, though the HDS721050CLA662 nevertheless continued to be the standard option from Hitachi's successor for 500 GB PCs.

Trivia[edit | edit source]

  • 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.
  • Some units report in ATA_IDENTIFY as "Hitachi HDS721050CLA660", with a "0" instead of a "2" like the majority of units.
