by subtest 2.
Subtest 11 restores the volume home block
and bad block table, if they are lost as a
result of running either subtest 3 or 23.
Normally, subtest 3 automatically saves the
volume home block and bad block table in an
internal buffer.
23 inadvertently writes over the volume home
block and bad block table (which is the case
with the default parameters), you can run
subtest 11 to rewrite the volume home block
and the bad block table automatically when
the test completes.
any reason, you should immediately run
subtest 11 to rewrite the volume home block
and bad block table.
Subtest 12 prints the contents of the volume
home b l o c k a n d bad block table.
Subtest 13 is reserved.
Subtest 14 toggles the alien mode flag for
the disk type specified.
mode flag is set, subtests 1, 6, and 7
interpret the disk as a nonstandard format
disk (i.e., no volume home block and
different bad block handling).
subtests are valid on a disk that is in
alien mode.
The alien mode flags for the
various disks are separate and can be set
and cleared independently.

that the disk driver can drive the disk.
Subtest 15, for floppy disks only, reads an
arbitrary floppy track that you specify.
(Subtest 15 does not display the data.)
Subtests 16 and 17 receive and transmit,
respectively, data stored on disk through
the fast communication (RS-422) port.
