The NCL
format is
somewhat more complicated. It will ask you
for drive number (0), number of
cylinders (615), number of
heads (4),
reduced write current (615), write precompensation
(615) and
maximum ECC data
error burst
length (11). The
numbers
given here in
parentheses would be typical for the
HMD-720-802. It will then ask if
all is correct; if
yes, it
proceeds with the format. If not,
it returns you to the top of
the input menu. In any case, when it completes the
format, it
may ask
you if
you wish to enter alternate track selections.
Tell it "no".
Invoke the program HDFMTALL. This
program will allow you to
reconstruct the bad track
table, which we just knocked out
with the physical format. HDFMTALL will
ask if
you
want a
"standard" format; press "N".
It will then ask if you want the
default interleave of 3;
you can
accept this
or change it.
(I've found that an interleave of 6 seems to be pretty optimal
on the I and
II.) HDFMTALL will then display the bad track
table and give you
the chance
to edit it. If any bad tracks
are displayed, make sure that any bad locations from the error
list you took off of the drive are indeed flagged. If not,
enter them manually. If the scan turned up
an excessive (more
than 50) number of bad tracks, you might want to delete them
and then manually enter the ones from the
error list. Press
"F" when you are finished and HDFMTALL will proceed with the
warnings and then the actual format.
6. You're now ready to use
HDPART. This program
sets up the
7.
MS-DOS partition
and
writes the DOS file structure to the
disk. Typically' you'll use the entire disk for
DOS,
so that
simplifies matters. Just make sure that the DOS partition is
specified as BOOTABLE. When
you
exit HDPART, the system
automatically re-boots.
The final
step - HDFORMAT. From the A prompt, enter the
following:
HDFORMAT C:
/s/v.
The /S switch transfers the
operating system to the hard drive.
The /V switch causes
HDFORMAT to prompt you for a volume name for drive C. HDFORMAT
now performs the logical format. When finished' remove the
floppy from
drive A and press CTRL-ALT-DEL. The system should
boot from the C drive.
For those of you familiar with the IBM world, the DEBUG format
is the
same.
HDFMTALL
is the equivalent to IBM's Diagnostics
level format;
HDPART is our version of FDISK, and HDFORMAT is
the same as IBM's FORMAT.
