Well this is fantastic! All my hardware seems to be dieing on me as of 
late! It's just not funny any more!

This disk is probably not even a month old either! Brand new Seagate 
7200.9. I've checked the smart status and it's showing no remapped bad 
blocks, which is reassuring...

Is this most likely just the cable? That last error looks quite 
worrying... I do believe that I have another disk attached on the same 
cable as that drive though, so I would have thought I would also be 
seeing errors on wd0. Hmm....
