SMDFMT - a utility that formats the
after extensive surface analysis.
flagged and will be ignored during
and reads.
PARAMETERS:
SMD disk drive
Bad sectors are
subsequent writes
Parameter 1 = disk unit to be analyzed and formatted
(Default: unit = 0). The range of units is 0 - 3.
Parameter 2 = number of scans of the disk during sur-
face analysis (Default: scans = 1). The range of scans
is the positive integers.
Parameter 3 = interactive mode. If interact = 0,
SMDFMT attempts to find the SMD disk size using an
algorithm similar to the one the SMD controller uses in
the SIZE command. If interact i 0, SMDFMT polls the
user for the disk size.
DESCRIPTION:
SMDFMT goes through most of the standard start-up pro-
cedure described in the INTRODUCTION TO SMD DIAGNOS-
TICS. However, since its purpose is to format a drive,
it does not issue the SIZE packet command. It also
omits the SEEK to CY = -1 step of the start-up pro-
cedure.
If interact = 0, SMDFMT will then do some investigation
to find the numbers of cylinders, heads and sectors-
per-track present on the drive. The results of its
investigation are displayed before formatting com-
mences. For the Model 31 80 Megabyte drives, the
correct numbers are:
# cylinders = 589
# heads = 7
# total sectors/track = 33
# active sectors/track = 32
If interact i 0, SMDFMT prompts the user for the disk
size parameters. Once the disk size is known, SMDFMT
will format the disk. The disk will initially be for-
matted with no sectors flagged as bad or spare (i.e.
all sectors will be formatted as active sectors).
