hi there,
i recently bought a western digital 1 terrabyte usb2/usb3 hdd:
[83611.209514] umass0: <MSC Bulk-Only Transport> on usbus3

i partitioned it via the gpt scheme and one big ufs2 partition with SU+J

mounting and everything works great. however if i don't access the monted hdd
for a couple of hours, and then do `ls /mnt/wd`, nothing is there. `mount -p`
reports that the hdd is still mounted:
/dev/ufs/rootfs / ufs ro 1 1

/dev/ufs/varfs /var ufs rw 1 2
/dev/ufs/usrfs /usr ufs rw 1 2

tmpfs /var/tmp tmpfs rw 0 0
/dev/ufs/wd /mnt/wd ufs rw,noexec,nosuid
0 0
`pwd` executed will return ENXIO. i can then do `umount /mnt/wd`, but
re-mounting the hdd fails with the following dmesg warnings:
[96836.840512] (probe0:umass-sim0:0:0:1): TEST UNIT READY. CDB: 0 0 0 0 0 0

(i believe the "probe0" stuff is from the umount)
`mount` fails with EPERM btw. what i have to do is: `fsck /dev/ufs/wd`. this
complains about the following:
** /dev/ufs/wd
USE JOURNAL? [yn] y
** SU+J Recovering /dev/ufs/wd
** Reading 33554432 byte journal from inode 4.
RECOVER? [yn] y
** Building recovery table.
** Resolving unreferenced inode list.
** Processing journal entries.
***** FILE SYSTEM MARKED CLEAN *****
...now everything is back to normal and i can mount the hdd again. any
suggestions? i'm running a very recent HEAD on amd64.
cheers.
alex
