Reminds me of the Maxtor DiamondMax Plus 8 disk firmware problem. This was a model of hard drive back in 2004-2005 that had a known issue where it would corrupt it's own firmware. The disk would literally overwrite and corrupt portions of firmware code which would render the disk unusable. Heat seemed to exacerbate the problem, and the problem caused the disks to generate a lot of heat so it was self-perpetuating. I worked at a hospital at the time, and we were upgrading from Win2k to WinXP, and replacing a lot of old HP Celeron 733 MHz systems with newer HP dc5000 AMD desktops. We deployed roughly 1,000 desktops over the course of a year and a half, and fully 25% of the systems that had a DiamondMax Plus 8 had disk failures within the first 6 months of deployment. Symptoms were always the same. System would get slower and slower until one day it would hard reboot itself and then claim there was no disk drive installed. BIOS would show the disk drive was present but that it had no capacity or name. Built-in BIOS self test would report a code 7 error. It got bad enough that we refused to deploy systems that shipped with those drives. Our manager had to fight with the sales rep for about a month before they relented. We were ready to go to Dell just to get away from those stupid disks.
