SCSIFMT
DESCRIPnON
SCSIFMT is the Ampro SCSI hard disk formatter utility.
It
is
used to perform the low-level
format for
SCSI
hard
disk drives, prior to final preparation
of
the drive using the standard
drive preparation utilities offered
by your operating system.
SCSIFMT supports the SCSI Common Command Set (CCS) direct access devices (typically
hard disk drives). Consult the specific
SCSI hard disk controller manual for information as to
compatibility with the
SCSI CCS.
SCSIFMT
can be used to completely reformat the target drive, and to map out bad blocks.
The list of bad blocks
is
appended to the on-disk bad block table, which
is
furnished
by
the
disk manufacturer.
OPERATION
Warning!
All
data
on
the
drive
you
format will
be
destroyed!
The general format of
SCSIFMT
is
as
follows:
SCSIFMT
Ii
[Ll]
[Zz] [F) [M[m))
[y]
The SCSI
ID
number, 0 through 7,
of
the SCSI device that is to
be
accessed.
This parameter is required
The Logical
Unit Number (LUN) of the SCSI device that is to be accessed.
If
not supplied, the default value is
O.
z
The
disk
interleave
factor, which only has
meaning
when
used
with
the
F
(format)
option.
If
not
specified
(or
set
to
0),
the
interleave
factor
is
left
unchanged from the drive's current setting. A typical value is
2;
most fast drives
when used with Ampro's
SCSI/BIOS can support
an
interleave factor of
1.
F The "format" option.
It
must be specified
if
you wish to format the drive (and
optionally change the interleave factor).
M The "map out" option. When selected, any bad blocks (blocks with read errors,
write errors,
or
both)
are mapped
out
of
the drive's block allocation table.
If
data
exists
in
the
bad
block,
an
attempt
is
made
to
safely copy
the
data
to
another block.
m The
number
of
clean passes for the bad-block
map
out. Specifies how many
passes must
be
made with no bad blocks found
If
not specified, defaults
to
1.
The maximum value
is
255.
A new pass begins when a bad block is found in the
current
pass. .
