Display a pseudo-graphical map of used versus free sectors in the filesystem
Display a usage map for the currently selected disk or filesystem
A pseudo-graphical map of the disk or partition allocation is
displayed, showing the distribution of data over the object
This is also an indication for the amount of unused sectors in
the object, that are beneficial to 'SMART-SECTOR' optimizations
in imaging and cloning operations.
The percentage of used sectors are displayed as a percentage at
the end of the line, and a total usage percentage and size is
shown just after the map itself.
For filesystems that support resizing, the limits for resizing
are shown after the map itself.

Display/Edit the standard 11-character label (in bootsector and ROOT DIR)
This will present a small dialog to display and/or edit the
standard (DIR) label, with a maximum length of 11-characters
and located both in the BOOTSECTOR and the ROOT directory
Both locations are updated simultaneously when editing
This standard label is used to identify the filesystem in
commands like DIR and FORMAT

Change the volume serial number, making this volume unique (after clone :-)
This will update the 'volume serial number' in the bootsector
This could be REQUIRED for some operating systems after cloning
a filesystem, to make sure the volume serial numbers are unique.

Fix bootsector by replacing from spare (FAT32) or create new
This will create a new FAT/FAT32 bootsector for the partition, using
information from the partition-tables, or for FAT32 by replacing it
with the spare-copy found at LSN 7
This can be very useful when the bootsector got damaged by a virus
or a crashing program (writing to sector 0) or if the partition was
deleted by accident using FDISK or LVM and recreated again.
You can specify the desired type for the bootsector in the
prompt dialog, with a default of M = MS-DOS, select from:
I or P IBM/PC-DOS with IBMBIO/IBMDOS.COM
M MSDOS with IO/MSDOS.SYS
O OS/2 with OS2BOOT
N Win-NT with NTLDR (FAT16)
9 Win-9x with WINBOOT.SYS (FAT32)

Fix bootsector HiddenSectors and geometry fields to match partition tables
This will update the 'hidden sectors' field in the bootsector
to match the offset to the partition-table the partition is
defined in and update the geometry Heads and Sectors field to
match the current disk geometry.
This could be REQUIRED for some operating systems like OS/2
to accept and mount the partition as a driveletter!

Reset the bad-sector administration to show ZERO bad-sectors or clusters
This will check for bad-sectors being present in the
filesystem and when present, reset to NO bad sectors.
FAT: Reset all 'BAD' values in the FAT to FREE
EFAT: Reset all 'BAD' values in the FAT to FREE
NTFS: Update $BadClus and $BitMap to reset bad-clusters
HPFS: Make the bad-sector-list in the spare-block empty
This can be very useful after cloning or imaging a partition
or disk that includes bad-sectors to a new replacement one.

Update FAT status field in the bootsector to indicate filesystem is CLEAN
This will update the fileystem-status field in the FAT bootsector
to indicate that filesystem is CLEAN.
This can be useful to avoid an automatic CHKDSK after a system-crash
Note: The filesystem itself is NOT cleaned in any way, it is just the
statusflag that is modified.

This will update the fileystem-status field in the FAT bootsector
to indicate that filesystem is DIRTY.

Check filesystem for inconsistencies and errors (Readonly, no fixing!)
This will perform a CHECK of the filesystem, somewhat like the
well-known CHKDSK but without automatically fixing anything.
The result of the check is a sector-lookup-table (SLT) that contains
information about all recognized filesystem areas that are in use.
Any error recognized will be flagged in the default display of
this SLT that is performed automatically by the CHECK command.

Unselect filesystem, reselect the same/first disk; enables Mode=FDISK menu
This will UNSELECT the current object/filesystem, and reselect a
whole physical disk, either the same disk as the partition was on,
or the first disk present in other cases.
This is a quick way to change to 'Mode=FDISK' and work on
disk-level issues
