Comment 15 for bug 213308

Linda, Se7h,

Thanks for playing along with these instructions. You may be able to get the device to mount by running:

$ mount -t vfat /dev/sde1 /mnt

(replacing sde1 as appropriate).

However, the error message Linda found was useful in helping Google a potential solution; see:
   http://ubuntuforums.org/archive/index.php/t-637776.html
which suggests that the problem is caused by a western digital drive (which Linda's dmesg indicates she has).
The most useful looking suggestion is:
== Someone on a mailing list pointed out this thread: http://ubuntuforums.org/showthread.php?t=586894&page=4
== Switching the drive to Single Drive mode (no jumper) fixed the problem.
== It looks like the problem is a Western Digital drive with a motherboard using the SiS chipset.

This probably involves opening up your case and unplugging a jumper from the back of your drive.

Is that something you can try doing? If it doesn't work, definitely try the mount -t vfat to get the dmesg and other
log messages I suggested originally.
