INITIALIZE ELEMENT STATUS (AutoLoader Only) (07h)
The INITIALIZE ELEMENT STATUS command causes the AutoLoader to eject the
cartridge that is in the DAT drive (if any) and return it to the slot in the magazine.
Then the magazine is initialized, checking each element for cartridges or any other
status relevant to that element. This command performs the same magazine
initialization as is performed by mounting a magazine and powering-up the drive
except that no cartridge is inserted into the drive.
