This is a configuration error.

RequiresMount, MountPoint, unmountCommand are for DVDs only.

Yes. Or rather, the directives above don't apply to file storage.

But it does not work.

Not me, but I know of others. Well, I kind of have - I operate simple
usb disks but without any special consideration regarding mounting etc.
These are setups where the disks are not meant to be removed.
Josh Fishers "Removable Disk Howto revised" is probably interesting for
you - you find it searching in the list archives.

Yes. But probably diferent than what you intend.

Yes.

Don't know.

No.
There's one other option, by the way: Try to understand how writing to
DVD works for Bacula. Then, create a script similar to dvd-handler -
basically, you could replace the invocations of growisofs with a cp, ge
the available space using df, and so on.
My original idea was that dvd-handler could be used as a template for
low performance storage systems like ftp, CD-RW and others, but
currently Bacula reads directly, so whatever media you use, you must be
able to mount it for reading. Writing can be done by a handler script.
