This will select the controller code CORVB5.CLR from drive B: .
This
file will be read in from the diskette and its identification
record
will be listed on the console. At the end
of
this printout, the
system
will ask
if
the format switch is
ON.
The update can usually
be done with the switch OFF but the program will only accept
an
answer
of
Y.

After the Y response the program asks for the Corvus drive # .
Once the drive # is given, the code will be written
out
to
the disk.
Should a disk
R/W
error occur here, there may be some hardware
problem or there may be some bad sectors in the firmware tracks
of
the drive. At the conclusion
of
the operation (no more than 20
seconds) the program will boast
of
its success and remind you
to
switch the format switch back to its normal position.
You
may verify that it has worked correctly by requesting the
VERSION option.
Formatting
the
drive
and
replacing the
firmware
Formatting a drive is a drastic measure and should only be
performed under extreme circumstances.
If,
however, it does be-
come necessary to reformat the drive (due
to
inability
to
write
firmware, bad tracks, etc.) some precautions should be taken. If
important data is on the disk, some attempt should be made
to
recover it,
as
the reformatting process destroys it. If possible, the
spare track
table should be written down as this may contain some
difficult to locate media errors which will cause trouble later
if
they
are not caught by the
CRC/FORMAT check.
