Just to follow up on this, it did get worse!By the time we got to the customer's site to look at it essentially both drives had gone awol. Even the BIOS did not report them present. Strangely when I took the system home last night I didn't have that problem. We measured the juice on-site and it varied from 190V to 247V AC yet their other computers didn't complain.
There's some anomalies in the attached and commented log extract though.In particular, even though we didn't change ATA ports (although I may have swapped the two drives between the ports we did use). Yesterday we were getting errors on ata3: and ata4: and yet later it was on ata2: so WTF is with that?
Plus... so far on every SATA system I've got I've had SATA errors of SOME kind and things keep running normally so I'm finding it hard to tell what's of concern and what's not.
Anyway hopefully some SATA guru can tell me down the track.For those that want a look at how a raid array dies view the attached file with zless.
