No, I don't have swap there. I suspect the binaries 'make release'
installed on /usr/release got corrupted.

Did that last time.

root@niobe ~# camcontrol modepage -n da -u 1 -m 1
AWRE (Auto Write Reallocation Enbld):  1
ARRE (Auto Read Reallocation Enbld):  1

There's nothing important there anyway:

root@niobe ~# df | grep da1
/dev/da1e      254063   211793    21945    91%    /usr/obj
/dev/da1g     5116967  3612584  1095026    77%    /mp3
/dev/da1f      762223    28696   672550     4%    /usr/release

Wilco.

OK.

I'm considering turning the disk in for a refund and buying an IBM
UltraStar instead.
