Hi Gavin,
 it isn't clear to me what help you want.

Obviously there is some sort of hardware issue - possible a drive, possibly a

Apart from that things look normal.

Also that there was excessive disk I/O even for trivial things like bring up a directory window, and lots of ata3 errors being reported to the system log.  These symptoms were mostly during a raid check process.
