NAME
mount_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 sys-
tem hierarchy 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 con-
taining 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 themissing arguments, including 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 asdevice-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. OPTIONSSunOS 5.11 Last change: 12 May 2008 1

generic_options
See mount(1M) for the list of supported options.-o
Specify pcfs file system-specific options. The following
options are supported: clamptime | noclamptimeFile timestamps in pcfs cover a range between Janu-
ary 1st 1980 and December 31st 2127. This is notequal 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 rangeof 32-bit time_t are encountered. In order to
prevent such spurious failures, pcfs by default clamps timestamps to the common subset of possiblepcfs timestamps and the range available to 32-bit
applications in Unix. The clamptime mount option therefore is active by default. If you want access to the full range of possible timestamps on pcfs, mount the file system with the noclamptime mountoption. Note that if noclamptime is used, only 64-
bit applications will have access to timestampsbeyond January 19th 2038, 03:14:06 UTC; 32-bit
applications will encounter EOVERFLOW errors. foldcase | nofoldcase Force uppercase characters in filenames to lowercase when reading 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. Whennohidden is effect, hidden and system files are nei-
ther visible nor accessible. Note that PCFS in pre-
vious releases of the Solaris operating system used the nohidden option as the default. atime | noatimeSunOS 5.11 Last change: 12 May 2008 2

Enable or disable write access timestamps on DOS-
formatted media. Default for fixed disks is atime, while for removable media noatime is used. Thelatter default is so that writes to flash-based
media ("memory sticks") can be minimized, to prolong lifetime. timezone=timezoneTimestamps on DOS-formatted media are recorded in
the local time of the recording system. This can cause confusion when accessing removable media inwhich the recording and receiving system use dif-
ferent time zones. Use this option to force media timestamps to be interpreted for a specific timezone. 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 asdescribed in environ(5) for the TZ environment vari-
able. By default, the timezone value is taken from the TZ environment variable. FILES /etc/mnttab table of mounted file systems /etc/vfstab list of default parameters for each file systemATTRIBUTES
