Ongoing disk issues

This has been going on for a while now. It's a relatively low frequency occurrence, but I just recently got a brand new SATA drive and transfered everything on to it, and the problem recurred, which surprises me.

This is a fairly late model machine - a Core 2 duo with the Intel ICH8 chipset.

Note the bizarre mingling of two different messages in there.

From the boot dmesg:

atapci2: <Intel ICH8 SATA300 controller> port 0xd400-0xd407,0xd080-0xd083,0xd000

This will probably continue until I get home from work this evening and switch the SATA cable over to another port, at which point the system will operate normally for a couple months and this will start again.

Weird.
 
A bit of a shot in the dark, but have you tried switching cables? Your block numbers are mostly different, which makes me a bit less likely to blame the disks themselves than I would be otherwise.

It could be the controller too, but I'd bet against that one...
