Mode=HFS Menu: [Apple MAC HFS+ journaled File System]

Allocation map display

From main menu: Mode=HFS -> Allocation map display

Display a pseudo-graphical map of used versus free sectors in the filesystem

Menu item screenshot(s)


    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.

Set Standard Volume Label

From main menu: Mode=HFS -> Set Standard Volume Label

Display/Edit the 255-character volume label located in the Catalog file tree


    This will present a small dialog to display and/or edit the
    standard volume label, with a maximum length of 255-characters
    and located in the Catalog file

    This standard label is used to identify the filesystem in
    commands like LS and FORMAT, and in the Finder application

    The actual label value is present in several of the Catalog Btree
    nodes, since it is by definition a Key-value. DFSee will update
    each of those nodes when changing the label string.

    The maximum allowed length may be limited due to the available
    space in all of the nodes to be updated.

    NOTE: Setting the label requires WRITE access to the volume!

          You can get that using the macOS DFSee version using:

          File ->
             Device and Volume management ->
                Unmount volumes from a disk ->
                   ... select the disk holding this volume ...

          (in Expert mode)

Display Superblock

From main menu: Mode=HFS -> Display Superblock

Display the SUPERBLOCK structure for the currently selected filesystem


    This will display the contents of the filesystem superblock
    in a textual format matching the current filesystem type.

Reselect whole disk, FDISK

From main menu: Mode=HFS -> Reselect whole disk, FDISK

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
