SUMMARY: removing old tapes (boot -r really necessary?)

        Unfortunately I had to reboot the system. The only answer I got was
from Adam Levin <>. He said that unpluggin SCSI
cables was not supported by the SCSI spec and I could have fried my
controllers. If you change things connected to a system via cables,
you must reboot.

        Thankfully nothing bad happened.
