Disk read error.

[Angrboda]

Not to dittohead Tibbs, but that sounds kosher off the top of my head.

Two little known facts about hard drive failure. First, of the hard drives returned to the factory under warranty, 80% have nothing wrong with them. Second, of those that genuinely have failed, 80% of the failures are in the drive electronics, not the disk or mechanicals. And obviously, only part of the chain of electronics is a part of the disk, the other being the cable, motherboard, and depending, power supply. (There are other obscure failures but they drop off in frequency, faulty memory being next, but I'm about to exhaust all the parts in a computer, thus making my savvy sounding diagnosis little more than a cheap trick with numbers.)

Oh, one last thing to squeeze in here. It's uncommon, but design flaws are not a rarity in computers. It might profit you to google around to see if others with the same hardware have experienced similar issues.

So why am I still talking. I don't know. I'm a hardware girl, and, and, and.... oh just bite it.
