What to do with a status report like the one included below?
What does it mean to have an unrecoverable error but no data errors?
Is it just a matter of `clearing' this device? But what would have
prompted such a report then?
Also note the numeral 7 in the CKSUM column for device c3d1s0. What
does it mean.
