I was going to write you that I had no idea, when I realized that I do
know (er guess) what the problem is. By default, mounted volumes -I'm
not sure it all the filesystems do the same, but vfat sure does- are
mounted asynchronously, what means that writes are deferred in time and
done later on, in order to improve performance.

When you umount the volume, any data not previously written is synced,
you can try writing 'sync' and then umounting it and you'll see the umount
is immediate (in case this is indeed the problem).

The best option is to add 'sync' to the mount options in your
/etc/fstab, the entry I have for my iFP is as follows:

/dev/sda /mnt/ifpdev vfat noauto,sync,noatime,user,nonumtail,shortname=mixed,codepage=850,iocharset=iso8859-15 0 0

For more info on all the options, you can read 'man mount' :)

I hope this helps ;-)
