I've been fighting my Sansa c250 mp3 player. After a reboot, I now have several volumes of the same name (each volume simply adds additional underscores to change the file name).

When I try to unmount, I receive the following:
/sbin/umount.hal: /media/Sansa c250___ is not recognized by hal

How can I kill these volumes? I'm sure it's a simple fix....

Ubuntu 7.10
The Sansa is not connected, so it's not currently running. See screenshot....it's friggin' huge... you can't miss it.
