This is the device name you should use in the DIR config.

This is the Media Type to use in the DIR config.

This is the name of the storage definition in the DIR.

Put in the name from the SD here: DellTL4000

It's better to not refer to the drives in the DIR as this might scre up
the volume-to-device relationships.

This will probably not work for a single drive.

I think my above suggestion should work.

I don't think so as it's possible to have an autochanger with drives
supporting different media types. I doubt anyone runs such a
configuration, though.

Hope this helps,
