About two months ago (back in July), I got some alarming error messages
about one of my disks, which has been spinning constantly since it was
turned on several years ago:

These messages appeared for a few days and then went away! The disk is
still in operation, and I havn't had any errors from it since... but its
death is on the the back of my mind...
Oh yeah, its a:
da1: <SEAGATE ST15150N 0017> Fixed Direct Access SCSI-2 device
da1: 10.000MB/s transfers (10.000MHz, offset 15), Tagged Queueing Enabled
da1: 4095MB (8388315 512 byte sectors: 64H 32S/T 4095C)
