52: * Archive drive:

55: *
56: * Supports Archive Viper QIC-150 tape drive, but scsi.c reports selection

58: *
59: * Supports Archive Python DAT drive, but will sometimes hang machine.
60: *
61: * Supports HP 35450A DAT drive, but will sometimes hang machine.
62: * Partitioning of tape not supported.
63: * Vendor unique support has not been added.
64: *
65: *
66: * Supports Archive VIPER (QIC-150).
67: * Mostly Supports Archive PYTHON (DAT).
68: * Hangs if write after spin down.
