It doesn't look particularly good. Do you run the smartd selftests at
all? Worth giving that a go --
# smartctl -t long /dev/ada5
This can be done while the disk is in use without upsetting anything.
It will scan the disk for unreadable areas. The disk does have a number
of spare sectors it can use instead of any broken ones, but it generally
needs to see a failed write to the affected area to trigger the
substitution mechanism. Once you run out of substitute sectors, the
disk is basically toast and should be replaced. With modern drives,
seeing that mechanism in use at all typically means the drive is on the
downward spiral and you should plan on replacing it PDQ.
