NAME

     fsck_exfat -- Verify and repair ExFAT file systems.

SYNOPSIS

     fsck_exfat -q device ...
     fsck_exfat [-f] [-p] [-y | -n] [-g | -x] [-d] device ...

DESCRIPTION

     The fsck_exfat utility verifies and repairs ExFAT file systems.

     The first form of fsck_exfat quickly checks the specified file systems to determine whether they were cleanly unmounted.

     The second form of fsck_exfat checks the specified file systems and tries to repair all detected problems, requesting confirmation before
     making any changes.  The default behavior is to always ask for confirmation of each change.  Use the -n or -y options to override this
     default behavior.

     The device parameter(s) should be a path to a "raw" disk device (a character special device), such as /dev/rdisk1s1.  If you specify a "non-
     raw" path (a block special device) such as /dev/disk1s1, or just the disk name such as disk1s1, they will automatically be converted to the
     corresponding raw disk device (/dev/rdisk1s1).

     The options are as follows:

	   -q	   Causes fsck_exfat to quickly check whether the volume was unmounted cleanly.  If the volume was unmounted cleanly, then the
		   exit status is 0.  If the volume was not unmounted cleanly, then the exit status will be non-zero.  In either case, a message
		   is printed to standard output describing whether the volume was clean or dirty.

	   -f	   This option is ignored by fsck_exfat and is present only for compatibility with programs that check other file system types for
		   consistency.

	   -p	   Preen the specified file systems.  This option is ignored by fsck_exfat and is present only for compatibility with programs
		   that check other file system types for consistency.

	   -y	   Causes fsck_exfat to assume yes as the answer to all questions.  It will attempt to repair all problems that are found.

	   -n	   Causes fsck_exfat to assume no as the answer to all questions.  The device will be opened read-only, and no repairs will be
		   made.

	   -g	   Causes fsck_exfat to produce its output in GUI-compatible form.  Each message is printed as a tuple containing the kind of mes-
		   sage, the message string, and number of parameters to the message string.  Any parameters to the message string are printed on
		   subsequent lines.  The message string uses NSLog-like substitutions.  This output format is used by applications such as Disk
		   Utility.

	   -x	   Causes fsck_exfat to produce its output in an XML-like form.  Each message is printed as a plist(5) containing a message type,
		   verbosity, message number, and message string.  The message string uses NSLog-like substitutions.  For message strings that
		   contain parameters, an array of dictionaries is output.  This output format is used by applications such as Disk Utility.  It
		   may be used by other kinds of applications which wish to parse the output of fsck_exfat.

	   -d	   Causes fsck_exfat to produce extra debugging output.  This generally contains additional details about problems found.  When
		   writing bug reports for fsck_exfat, it is usually helpful to include the output generated from this option.
