One thing to keep in mind if you do this - if you move the drive to
another machine where the UID and GID for alan are different, you
will not be able to access the drive as alan. The owner/group
settings are the number, not the name, of the user/group.

You may want to use chown alan:alan /media/Devel instead of chown
alan /media/disk. This will set both the owner and group of the
disk. In this case, I would not use the -R option - I do not know
what the affect of changing the ownership of /media/Devel/lost+found
would be.

You also have the option of creating a directory on the USB drive
owned by alan. That way, you could have storage for more then one
user on the drive.
