Hm... At quick glance, that looks fine. Does the player work normally with any existing music? You mentioned that you are going over ethernet. Can you...

a) try doing a hyperterminal capture of the console while the sync is happening to see if there are any error messages?

b) try doing a sync with USB to eliminate ethernet as an issue?

c) diable any and all third party software that may have an open file on the player - making it so emplode cannot dismount the filesystems.

d) do a manual disk check to eliminate that as the source of any problem?

Thanks.
