Frstly, you need to make sure that you are mounting the correct partition on
the correct device.

Do the following:

cat /proc/scsi/scsi

Look at the device listings. In each entry there may be an acronym for each
slot e.g. CFC for the CF card slot. Once you have identified the device that
you want to mount, use fdisk -l /dev/sd? where ? is the disk letter. This
should then list any partitions and their numbers on the device. Now try
mounting the device from the shell to see if it works.
