Deskstar

In 2012, Hitachi sold the division to Western Digital, who continued the drive product line brand as HGST Deskstar.

[4] The IBM Deskstar 75GXP (six models ranging in capacity from 15 to 75 GB) became infamous circa 2001 for their reportedly high failure rates,[5][6] which led to the drives being colloquially referred to as "Deathstar".

Despite failures being reported within the manufacturer warranty period of three years, Michael T. Granito, Jr., an American user of IBM's 75GXP hard drives, filed a class-action lawsuit against IBM on 16 October 2001 for defects in the product causing it to "crash", with both of the drives he had bought having failed within a short time.

The combination of two technologies, GMR (Giant Magneto-Resistive) heads on 3.5-inch glass platters, are said to be largely to blame for the issues.

[16] The Deskstar documentation was updated to show that the drives had been rated to 333 power-on hours per month (45 percent), leading to speculation that this was the result of the lawsuit.

Five disks removed from a dead IBM Deskstar 75GXP which failed in a server at the University of Florida in April 2003. Ten heads crashed so severely that almost all the magnetic media was removed from the flying part of the disks' surfaces revealing the transparent glass substrates. One disk in the upper left has some magnetic material on a portion of the head flying region.
