I'm currently running Ubuntu Edgy Eft and have been trying to get copycover-offline.py to work.  The problem is that I keep getting an error like this -

  ERROR: No write access to ./media/mediaX/Music/Nightwish

The FS is fat32 and is shared between Linux and my Windows install for all my media.  I've managed to change the permissions a few times so that my default user has complete access but I still get the error.  Can anybody help me with this?

You are sure you actually have write access at the time you run the script?
You can alter your fstab to change this permamently (see man mount and have a look at the section for the fat options, especially the uid, gid and umask option which can be set in fstab in the options column).

I am not familiar with this script, but maybe the path is wrong at all which might cause the very same error.
