Disk overview map

From main menu: Display -> Disk overview map

Compact map display of all partitionable media, showing the partitions

Menu item screenshot(s)


    This will display an overview of the partitionable media.

    For each disk a pseudo-graphical map will be shown, with each
    partition or freespace area sized and colored according to its
    real size and type of filesystem being used.

    Some key information for each area will be shown inside each
    partition or freespace area displayed.
    Note that a 'disk' can be any partionable media supported by
    DFSee, like physical disks, virtual-disks and others ...

Disk/filesystem Usage

From main menu: Display -> Disk/filesystem Usage

Screen-size map of disk or filesystem usage, allocated versus freespace info

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.

Object Geometry+Status c-W

From main menu: Display -> Object Geometry+Status c-W

Show (disk) geometry for currently opened object, including some status info


    This will display the (disk) geometry currently used by DFSee

    The geometry, as a Cylinder, Head and Sectors-per-track count
    plus the size in a hexadecimal sectorcount and in MIB can be:

       L-Geo, the logical geometry, used by DFSee for all its work

       S-Geo, the system geometry, as reported by the operating system
              only displayed when different from the logical geometry.

    As with nmost commands, the display ends with a status overview of
    the currently opened object in just two lines that show you what
    type and size of object is opened, and what the current/next/prev
    positions in that object are, shown as hexadecimal sectornumbers.

    This is a form of the verbose partition list, that will include
    a 'check' of the filesystem in every partition, if that is
    supported in DFSee for the filesystem in question.

    Note that this is similar in function to the familiar CHKDSK on,
    Dos, Windows or OS/2 but is does checking only, there is NO writing
    to the disk at all, and found errors will NOT be repaired!

    Some of the reported errors can be fixed by using other 'FIX...'
    commands available in DFSee, othere will have to be fixed by
    other means, for example: 'CHKDSK /f'.

    from the 'File' menu, or an implicit open by some other command or menu
    selection made previously.

    The display show information kept for all open objects in the 'STORE'
    administration that can hold information about three simultaniously
    open objects (see 'STORE' command documentation).

    Normally, only a single object will be opened, using the CURRENT store, but commands like 'CLONE' will use the second 'ALTERNATE' store as well
    keeping information about the source of the clone ...

      Description     The (Linux) device name for this disk device,
                      an Image filename and/or details on the medium

    All entries in this table can be used as a 'disk' in the many
    DFSee commands that deal with them, and these are also listed
    in the default partition and MAP displays in DFSee.

    Note that the 'Disk-id' is really a 'Partionable Medium Id',

Menu item screenshot(s)


    This will display all partitioning related sectors for a partition,
    the MBR or EBR sector, the bootsector (PBR) and LVM sectors, if any.

    This is the quickest way to get all partitioning related information
    displayed for one partition.

    It uses the 'pt  PID  -r' command to show the partition-table entry
    and all related sectors for the selected partition 'PID'.

    To display this related sector(s) information for all partitions, use:

          Display -> Other partition views -> Part sector(s) view

    Note: If you have a partition, volume or device selected, and are NOT
          in FDISK mode, this selection will switch to that automatically

    This will display the 'next likely' sector on the current opened store
    by using the 'next' value set by any previous display of a sector.

    Displaying the 'next' sector (Ctrl+N) on an opened filesystem will
    show the most interesting sectors like bootsector, superblocks etc.

    In general, each display function will set this 'next' value to the
    sector that is the most 'desirable' to be visited/displayed next.

    This will display the 'up' sector on the current opened store
    by using the 'up' value set by any previous display of a sector.

    In general, each display function will set this 'up' value to a
    sector that is related, and probably 'upwards' in the hierarchy
    from the current sector.
    As an example, when displaying an HPFS file FNODE, the 'up' will
    take you to the directory FNODE of the directory holding the file.

    In general, each display function will set this 'xtra' value to a
    sector that might be of interest.

    As an example, when displaying a partition-table sector, the 'xtra'
    will take you to the related LVM DLAT sector for that partition.

    to using the default or specified buffer size.

    After completing the 10 second interval, or reaching the end of the
    object, the througput will be displayed.

    Because reading and directly writing the SAME area will have a very
    high impact on performce (cache, head-movement), expect a Read/Write
    throughput at least 10 times less than Read-only!

I/O speed Larger Buffer

From main menu: Display -> I/O speed Larger Buffer

Measure RAW I/O speed using a larger buffer, default for compressed IMAGING


    This will measure and display the I/O speed for a 10 second interval
    using a relatively LARGE buffer, often faster than a small one.

    The current objecty (disk, partition etc) will be read only,
    using the same buffer size that is default for imaging, which
    is 256 KiB for the DOS version, and 2 MiB for the other platforms

    After completing the 10 second interval, or reaching the end of the
    object, the throughput will be displayed.
