Hi Andy,

I have the same problem with my drive. I unmounted it properly, and
still had the problem. I haven't found a solution yet, but I did find
a work-around.

Run "sudo chown <user>:\ /media/<mountpoint>" in a terminal, and
you're able to write to the drive again.

Obviously, change <user> to your username, and <mountpoint> to the
directory at which the drive is automounted. E.g. my command was
actually "sudo chown neil:\ /media/FREECOM".

HTH. I'm interested in any long-term solution too.
