Obsession HDD Controller Failure
If you have the hard drive replaced from an Obsession I with an early motherboard, there is a chance you will get a "HDD Controller failure" message in the diagnostic screen. This happens from putting a new hard drive into an old computer that has problems keeping up. This is not something to worry about and simply needs a reboot (unplug and re-plug works). There are no adverse affects once it boots to Obsession software.
