file system errors

[Daniel Dalton <d.dalton@iinet.net.au>]

Hi,

Ok, here is what I'm trying to do:
Sync music files from my computer, to my 20 gb mp3 player.
There is 8 gb of data to sync
However, midway through the sync process, the fs is set to read only as
there seem to be errors with certain files.
If I remount, I can't remove these effected files, the only way to fix
things is to make use of fsck.vfat -wa.
So, I can't continue syncing as if I get rid of the effected files, they
just come back on the next sync.
There is no problem on the ext3 file system. So how can I stop this from
happening, and get a clean sync. Do I remove the effected files from the
ext 3 fs, or is there another way to tell rsync to skip the files. How
do I see what files are causing the trouble? 
I believe the file system is fat 32 on the mp3 player, this is the
command I used to make it:
sudo mkfs.vfat /dev/sdg1
Oh and here is my rsync command I use.
rsync -avz /media/daniel-external/music/ /media/disk/music 

If anyone could help me out with this I'd greatly appreciate it.

Thanks, 
Dan.
