Here is the sequence of events I see:
1. Plug in disk
2. HAL reports the error "org.freedesktop.Hal.UnknownError. An unknown
error occurred" I get two pop-ups with this, si I assume it is failing
twice.
2a. The device is mounted. (I assume this is a problem with trying to
mount the multiple different instances of the device in /dev, /dev/ufs,
and /dev/ufsid).
3. mount(8) shows:
/dev/ufs/WindowsVBd on /media/WindowsVB (ufs, local,nosuid, soft-updates)
4. Request umount of device
5. Device unmounts correctly
6. Device immediately re-mounts as in 2 and 2a, including errors
7. mount now shows:
/dev/ufs/WindowsVBd on /media/WindowsVB_ (ufs, local, nosuid, soft-updates)
The only difference is the '_' added to the mount point as the prior
mount point was not deleted when the disk was unmounted.
The things I wonder about is confusion due to the three /dev entries,
two of which start with '/dev/ufs' and the 'd' appended to the /dev/ufs
name due to the fact that it is the 'd' partition of the slice.
Here are the relevant entries from lshal:
