MOUNT_PCFS(1M)MOUNT_PCFS(1M)NAMEmount_pcfs - mount pcfs file systems
SYNOPSIS
mount -F pcfs [generic_options]
[-o FSType-specific_options] special | mount_point
mount -F pcfs [generic_options]
[-o FSType-specific_options] special mount_point
DESCRIPTION
mount attaches an MS-DOS file system (pcfs) to the file system hierar‐
chy at the mount_point, which is the pathname of a directory. If
mount_point has any contents prior to the mount operation, these are
hidden until the file system is unmounted.
The pcfs file system supports direct mounting of files containing the
file system as well as block devices. See mount(1M) and lofiadm(1M).
If mount is invoked with special or mount_point as the only arguments,
mount will search /etc/vfstab to fill in the missing arguments, includ‐
ing the FSType-specific_options; see mount(1M) for more details.
The special argument can be one of two special device file types:
o A floppy disk, such as /dev/diskette0 or /dev/diskette1.
o A DOS logical drive on a hard disk expressed as device-
name:logical-drive , where device-name specifies the special
block device-file for the whole disk and logical-drive is
either a drive letter (c through z) or a drive number (1
through 24). Examples are /dev/dsk/c0t0d0p0:c and
/dev/dsk/c0t0d0p0:1.
The special device file type must have a formatted MS-DOS file system
with either a 12-bit, 16-bit, or 32-bit File Allocation Table.
OPTIONS
generic_options
See mount(1M) for the list of supported options.
-o
Specify pcfs file system-specific options. The following options
are supported:
clamptime | noclamptime
File timestamps in pcfs cover a range between January 1st 1980
and December 31st 2127. This is not equal to the range of
time_t on Unix for either 32-bit or 64-bit applications. In
particular, 32-bit applications fail with EOVERFLOW errors on
the stat(2) system call when timestamps beyond the range of
32-bit time_t are encountered. In order to prevent such spuri‐
ous failures, pcfs by default clamps timestamps to the common
subset of possible pcfs timestamps and the range available to
32-bit applications in Unix. The clamptime mount option there‐
fore is active by default. If you want access to the full range
of possible timestamps on pcfs, mount the file system with the
noclamptime mount option. Note that if noclamptime is used,
only 64-bit applications will have access to timestamps beyond
January 19th 2038, 03:14:06 UTC; 32-bit applications will
encounter EOVERFLOW errors.
foldcase | nofoldcase
Force uppercase characters in filenames to lowercase when read‐
ing them from the filesystem. This is for compatibility with
the previous behavior of pcfs. The default is nofoldcase.
hidden | nohidden
Allow or disallow listing of files with hidden or system bits
set. Option hidden is the default. When nohidden is effect,
hidden and system files are neither visible nor accessible.
Note that PCFS in previous releases of the Solaris operating
system used the nohidden option as the default.
atime | noatime
Enable or disable write access timestamps on DOS-formatted
media. Default for fixed disks is atime, while for removable
media noatime is used. The latter default is so that writes to
flash-based media ("memory sticks") can be minimized, to pro‐
long lifetime.
timezone=timezone
Timestamps on DOS-formatted media are recorded in the local
time of the recording system. This can cause confusion when
accessing removable media in which the recording and receiving
system use different time zones. Use this option to force media
timestamps to be interpreted for a specific time zone. The
mount_pcfs command converts the given time zone name into a
numerical offset that is passed to the pcfs kernel module,
using the same rules as described in environ(5) for the TZ
environment variable. By default, the timezone value is taken
from the TZ environment variable.

If the directory on which a file system is to be mounted is a symbolic
link, the file system is mounted on the directory to which the symbolic
link refers, rather than on top of the symbolic link itself.
