NAME
rmformat - removable rewritable media format utility
SYNOPSIS
rmformat [-DeHUv] [-b label] [-c blockno]
[-Fquick | long | force ] [-s filename] [devname]
rmformat -V read | write devname
rmformat -l [devname]
DESCRIPTION
The rmformat utility is used to format, label, partition, and perform
other miscellaneous functions on removable, rewritable media that
include PCMCIA memory and ata cards. The rmformat utility should also
be used with all USB mass storage devices, including USB hard drives.
This utility can also be used for the verification and surface analysis
and for repair of the bad sectors found during verification if the
drive or the driver supports bad block management.
After formatting, rmformat writes the label, which covers the full
capacity of the media as one slice on PCMCIA memory cards. The parti‐
tion information can be changed with the help of other options provided
by rmformat.
OPTIONS
The following options are supported:
-b label
Labels the media with a SUNOS label. A SUNOS volume label name is
restricted to 8 characters. For media size greater than 1 TB, an
EFI label is created. For writing a DOS Volume label, the user
should use mkfs_pcfs(8).
-c blockno
Corrects and repairs the given block. This correct and repair
option may not be applicable to all devices supported by rmformat,
as some devices may have a drive with bad block management capabil‐
ity and others may have this option implemented in the driver. If
the drive or driver supports bad block management, a best effort is
made to rectify the bad block. If the bad block still cannot be
rectified, a message is displayed to indicate the failure to
repair. The block number can be provided in decimal, octal, or
hexadecimal format.
The normal PCMCIA memory and ata cards do not support bad block
management.
-e
Ejects the media upon completion. This feature may not be available
if the drive does not support motorized eject.
-F quick | long | force
Formats the media.
The quick option starts a format without certification or format
with limited certification of certain tracks on the media.
The long option starts a complete format. For some devices this
might include the certification of the whole media by the drive
itself.
The force option to format is provided to start a long format with‐
out user confirmation before the format is started.
On PCMCIA memory cards, all options start a long format.
-l
Lists all removable devices. By default, without any options,
rmformat also lists all removable devices. If the dev_name is
given, rmformat lists the device associated with the dev_name. The
output shows the device pathname, vendor information, and the
device type.
-s filename
Enables the user to lay out the partition information in the SUNOS
label.
The user should provide a file as input with information about each
slice in a format providing byte offset, size required, tags, and
flags, as follows:
slices: n = offset, size [, flags, tags]
where n is the slice number, offset is the byte offset at which the
slice n starts, and size is the required size for slice n. Both
offset and size must be a multiple of 512 bytes. These numbers can
be represented as decimal, hexadecimal, or octal numbers. No float‐
ing point numbers are accepted.
To specify the size or offset in kilobytes, megabytes, or giga‐
bytes, add KB, MB, GB, respectively. A number without a suffix is
assumed to be a byte offset. The flags are represented as follows:
wm = read-write, mountable
wu = read-write, unmountable
ru = read-only, unmountable
The tags are represented as follows: unassigned, boot, root, swap,
usr, backup, stand, var, home, alternates.
The tags and flags can be omitted from the four tuple when finer
control on those values is not required. It is required to omit
both or include both. If the tags and flags are omitted from the
four tuple for a particular slice, a default value for each is
assumed. The default value for flags is wm and for tags is unas‐
signed.
Either full tag names can be provided or an abbreviation for the
tags can be used. The abbreviations can be the first two or more
letters from the standard tag names. rmformat is case insensitive
in handling the defined tags & flags.
Slice specifications are separated by :
For example:
slices: 0 = 0, 30MB, "wm", "home" :
1 = 30MB, 51MB :
2 = 0, 100MB, "wm", "backup" :
6 = 81MB, 19MB
rmformat does the necessary checking to detect any overlapping par‐
titions or illegal requests to addresses beyond the capacity of the
media under consideration. There can be only one slice information
entry for each slice n. If multiple slice information entries for
the same slice n are provided, an appropriate error message is dis‐
played. The slice 2 is the backup slice covering the whole disk
capacity. The pound sign character, #, can be used to describe a
line of comments in the input file. If the line starts with #, then
rmformat ignores all the characters following # until the end of
the line.
Partitioning some of the media with very small capacity is permit‐
ted, but be cautious in using this option on such devices.
-U
Performs umount on any file systems and then formats. See mount(8).
This option unmounts all the mounted slices and issues a long for‐
mat on the device requested.
-V read | write
Verifies each block of media after format. The write verification
is a destructive mechanism. The user is queried for confirmation
before the verification is started. The output of this option is a
list of block numbers, which are identified as bad.
The read verification only verifies the blocks and report the
blocks which are prone to errors.
The list of block numbers displayed can be used with the -c option
for repairing.
OPERANDS
The following operand is supported:
devname
devname can be provided as absolute device pathname or relative
pathname for the device from the current working directory or the
nickname, such as cdrom or rmdisk.
For systems without volume management running, the user can also
provide the absolute device pathname as /dev/rdsk/c?t?d?s? or the
appropriate relative device pathname from the current working
directory.
EXAMPLES
Example 1 Formatting Removable Media for a PCFS File System
The following example shows how to create an alternate fdisk partition:
example$ rmformat -F quick /dev/rdsk/c0t4d0s2:c
Formatting will erase all the data on disk.
Do you want to continue? (y/n)y
example$ su
# fdisk /dev/rdsk/c0t4d0s2:c
# mkfs -F pcfs /dev/rdsk/c0t4d0s2:c
Construct a new FAT file system on /dev/rdsk/c0t4d0s2:c: (y/n)? y
#
FILES

priate alias.

ata cards and removable media devices.
/dev/rdsk

NOTES
A rewritable media or PCMCIA memory card or PCMCIA ata card containing
a ufs file system created on a SPARC-based system (using newfs(8)) is
not identical to a rewritable media or PCMCIA memory card containing a
ufs file system created on an x86 based system. Do not interchange any
removable media containing ufs between these platforms; use cpio(1) or
tar(1) to transfer files on memory cards between them. For interchange‐
able filesystems refer to pcfs(4FS) and udfs(4FS).
rmformat might not list all removable devices in virtualization envi‐
ronments.
BUGS
Currently, bad sector mapping is not supported on PCMCIA memory cards.
Therefore, memory card is unusable if rmformat finds an error (bad sec‐
tor).
