trouble mounting Olympus WS-310M voice recorder

[Andrew Gould]

Background:  The Olympus WS-310M digital voice recorder has a standard USB interface and uses flash memory to store sound files.  Unfortunately, this device only records to WMA files.  I was able to view the filesystem on my MacMini without installing any software.  I'm trying to mount it to my FreeBSD system so that I can use ffmpeg to convert the WMA files to a more universally readable format.

Problem:  I am having trouble mounting this device in FreeBSD 6.2.

Here is the related dmesg output:

     umass0: OLYMPUS CORPORATION DIGITAL VOICE RECORDER, rev 1.10/1.00, addr 3

Here is the output from 'fdisk /dev/da0':

Here is the output from 'ls /dev/da0*':

     /dev/da0        /dev/da0s1

Here is the output of my various attempts at mounting this device as root:

attempt:  mount -tmsdos -orw /dev/da0 /mnt/ws310
result:     mount_msdosfs: /dev/da0: Invalid argument

attempt:  mount -tmsdos -orw /dev/da0s1 /mnt/ws310

result:     mount_msdosfs: /dev/da0s1: Invalid argument


Attempts with '-oro' instead of '-orw' had similar results.

What am I doing wrong?

Thanks,
