As suggested, I ran amtapetype on my Superloader 3 LTO6 drive.  It
took ~6 hours, here's the output:

-> amtapetype -f /dev/st0

Device is busy.  Amtapetype will retry forever; hit ctrl-C to quit.
Drive was busy for 38 seconds.
If this device is used in a changer, you may want to set timeouts appropriately.
