IDE harddrive errors

Hello,

I woke up this morning, feeling the effects of alcohol until I found my 
server erring weird messages such as this:

Sep 18 06:23:08 gate /bsd: wd1(pciide0:1:0): timeout
Sep 18 06:23:09 gate /bsd: 	type: ata

Sep 18 06:23:09 gate /bsd: wd1: soft error (corrected)

And this:

I'm running GENERIC.
Can anyone explain what causes these messages?
