Actions Menu: [Actions like erasing, cloning and resizing]

Open partition, Browse s-F9

From main menu: Actions -> Open partition, Browse s-F9

Select and open a partition, then Browse its filesystems directories / files


    This will present a selection-list of partitions, and after
    selection will continue with a regular 'browse' session on
    the opened partition/filesystem (like the <F9> action).

    This is useful mainly to browse several filesystems/partitions
    in succession, since after exiting a browse session, starting
    another browse (with <F9> for example) will just restart it on
    the same filesystem, with a choice of using the last directory
    or start in another specified path.

Browse FS, directory/files F9

From main menu: Actions -> Browse FS, directory/files F9

Browse files/directories in a list from a single directory, or current list

Menu item screenshot(s)


    This will show the contents of a single directory, specified
    by a PATH from the ROOT directory, or by selecting a directory
    from the browse list itself (including the '..' directory).

    Alternatively, the CURRENT contents of the sectorlist can be
    browsed, when available (by specifying a '.' for the directory

    The list can be browsed in an interactive dialog, a bit like
    a regular filemanager.

    The dialog will allow 'actions' to be performed on the listed
    files/directories, using <ENTER> to get the popup menu:

                 - View contents, as ASCII on File/Dir
                 - View as x86 Assembler - disassembly
                 - HEX-edit, contents only on File/Dir
                 - Edit Contents, autoview on File/Dir
                 - View OS/2 EA or Xattr on a File/Dir
                 - Edit DATA area sectors for File/Dir
                 - Edit META:Inode/Fnode/MFT/Dir-entry
                 - Edit the base filename for File/Dir
                 - Copy/Recover File(s) to other drive
                 - Reduce list to SELECTED files only

    When the browse session is ended (<Esc> or <F3> key):

      - the SAME filesystem/partition stays selected
        You can restart browse the same partition with the <F9> key,
        or start browsing another partition from the Actions menu
        using: 'Actions -> Open Partition, Browse FS'

      - the sector-list contains the last browsed directory
        and can be viewed with commands like 'list -f

      - The last entry (file) that was selected will also be set
        as the current sector-location ('this'), so it easy to
        analyse that furthher, for example by using the HEX-editor
        that can be started with <F2>, or simply by viewing the
        sector using the <Enter> key.

    Note: When working in 'mode=FDISK' (with a whole disk opened)
          you will be presented with a selection-list to pick a
          partition with a filesystem first.

Bad-sector scan, read only

From main menu: Actions -> Bad-sector scan, read only

Scan for bad-sectors using Read-Only (fast); It shows the disk-speed as well

Menu item screenshot(s)


    This will try to read every sector of the current opened object,
    and report on any read-errors encountered along the way.
    The object may be a disk, partition, volume or even an image.

    All unreadable sectors will be added to the sector-list for later
    reference and can be exported to a file from there as well.

    After ending the SCAN at the end of the object, or when <Esc> is
    used to terminate it, the speed of reading is calculated and
    displayed too. This is a good indication for read-performce.

Full read/write/verify Scan

From main menu: Actions -> Full read/write/verify Scan

Scan for bad-sectors using Read/Invert/Write/R/I/W, NON-DESTRUCTIVE but slow

Menu item screenshot(s)


    This is similar to the readonly SCAN, but it will write to the
    object as well as read. To make sure no data is lost or damaged
    doing that, it is actually a read-invert-write-read-invert-write'
    cycle with a verify of the data after the second read.

    This makes it a very reliable and safe method of finding bad sectors
    but it also makes it VERY SLOW! (up to 20 times slower than a RO-SCAN)

    All unreadable sectors will be added to the sector-list for later
    reference and can be exported to a file from there as well.

    After ending the SCAN the speed of scanning is calculated and
    displayed too. This is an indication for read/write-performce, but
    since there are TWO reads and writes in every cycle the number must
    at least be doubled.

    Combined read/write is much slower than just reading or just writing
    because it messes up the disk-caching.

Erase, wipe current object

From main menu: Actions -> Erase, wipe current object

Wipe object (disk/part/vol) completely clean with zeroes. (ALL DATA LOST!)


    This will erase ALL DATA on the current object by filling all
    sectors with ZEROES. Only the most advanced data-recovery methods
    would be able to recover data after wiping it this way.

    It removes any remains of partitioning information when used on a
    disk, or of confidential file-data when used on a partition or
    a whole disk.

Format partition as FAT(32)

From main menu: Actions -> Format partition as FAT(32)

FORMAT a partition to an EMPTY FAT or FAT32 filesystem (all data is LOST!)


    This selection will perform a FORMAT of the partition to be 
    selected to the FAT or FAT32 filesystem format, after setting
    options in a dialog with the following fields:

    Cluster size      Only VALID clustersizes will be presented,
    ( )  1 sector     and an optimal default value will be set
    ( )  2 sectors    as the active selection.
    ( )  4 sectors
    (*)  8 sectors    Small clusters may reduce wasted space with
    ( ) 16 sectors    many small files, while large clusters may
    ( ) 32 sectors    decrease fragmentation and increase the read
    ( ) 64 sectors    and write performance for large files.

    ( ) 12-bit FAT    Used below 4096 clusters (like diskettes)
    ( ) 16-bit FAT    Used up to 2 GiB, readable on many OS's
    (*) 32-bit FAT    Used beyond 2 GiB, or when a small cluster
                      size is desired for other reasons.

    Use boot-code aimed at OS:   [Windows 9x ]

                      This allows you to select between several
                      bootcode variants allowing it to actually
                      boot that related operating system.
                      NOT RELEVANT for data partitions!

     Root entries     The number of directory entries that are
    [512         ]    available in the ROOT directory (FAT12/16)

     Volume Label     The label as recorded in the bootsector as
    [DFSee123456 ]    well as the ROOT directory of the FAT FS
                      The default reflects the partition location

     SerialNumber     Volume serial number, should be unique for
    [ee123456    ]    removable media. Default based on location
                      or timestamp when it is not a partition.

     Offset FAT-1     Offset from the bootsector to first FAT area
    [1           ]    default 1 for FAT12/16 and hex 20 for FAT32.

    [ ] Use LONG format, initialize all clusters to ZERO contents

        This will erase the whole data-area, making sure no old
        information is retained. Note that, unlike regular FORMAT
        the current DFSee version does NOT check for bad-clusters!

    Formatting a partition or volume will destroy ALL data
    that is currently on it, and is NOT recoverable!

Selection of this item leads to a dynamic created submenu, to select a partition to be used


Resize partition and FS

From main menu: Actions -> Resize partition and FS

Resize partition (-tables) and the filesystem structures in that partition


    This submenu contains all menu-items related to RESIZING

    In all cases, you NEED to have a harddisk-partition selected for
    the menu-entries to be enabled, making the functions available.

      Limitations:

      The RESIZE menu is implemented using a generic command, but
      it requires a filesystem dependent part to be implemented.
      Currently that is ONLY available for FAT, FAT32, HPFS and NTFS

Resize, make partition smaller

From main menu: Actions -> Resize partition and FS -> Resize, make partition smaller

Resize the current partition, making it smaller (truncating, make freespace)


    This will resize the current partition to a size that is SMALLER
    than its present size, in other words, TRUNCATE the partition

    You will be prompted to specify a new size for the partition, with
    a minimum and a maximum value displayed for your convenience.
    The size entered will be rounded to make the partition cylinder
    aligned, just like any newly created partitions.

    When the system uses (IBM-style) LVM-information, it will be
    updated to reflect the new size of the partition.

    Data within the partition will NOT BE MOVED by DFSee, so to make a
    resize possible it may be needed to defragment it, or otherwise
    optimize the partition so that the data is moved to the beginning.

    A reason to resize partitions is to make freespace available to
    allow installation of another operating system.

      Limitations:

      The RESIZE menu is implemented using a generic command, but
      it requires a filesystem dependent part to be implemented.
      Currently that is ONLY available for FAT, FAT32, HPFS and NTFS

Expand, make partition larger

From main menu: Actions -> Resize partition and FS -> Expand, make partition larger

Resize the current partition, making it larger (expanding, using freespace)


    This will resize the current partition to a size that is LARGER
    than its present size, in other words, EXPAND the partition

    You will be prompted to specify a new size for the partition, with
    a minimum and a maximum value displayed for your convenience.
    The size entered will be rounded to make the partition cylinder
    aligned, just like any newly created partitions.

    When the system uses (IBM-style) LVM-information, it will be
    updated to reflect the new size of the partition.

    Expanding a partition is often done to use remaining freespace
    on the disk for an existing partition. However, DFSee will only
    allow expanding a partition to use freespace that is DIRECTLY
    after the partition.

      Limitations:

      Expanding is supported for FAT32, NTFS and HPFS filesystems.

      FAT16 fileystems can only be expanded to about 65500 clusters,
      at most doubling the current partition size. This is because
      the clustersize itself can not be changed using DFSee.

Adjust FS to partition size

From main menu: Actions -> Resize partition and FS -> Adjust FS to partition size

Resize the filesystem in current partition to use the WHOLE partition size


    This will adjust the filesystem present in the current partition
    to take up the WHOLE size of the partition ('resize -max')

    Usually this will mean making the filesystem LARGER so it fills
    the whole partition, and not just the start of it as may happen
    after restoring a filesystem-image to a partition that is larger
    than the original one was.

    In some cases it could also make the filesystem SMALLER to make
    it fit in the current partition. This will only work correctly
    if the end of the partition (that does not fit) was EMPTY.
    This may happen when restoring a filesystem-image into a
    a partition that is smaller than the original was.

Copy Part to freespace area

From main menu: Actions -> Copy Part to freespace area

Copy current partition to a different freespace area, do NOT delete original


    This will CLONE the whole partition contents to another freespace
    area selected from a list of suitable ones. The original partition
    will NOT be deleted making the result a true COPY ...

    Only freespace areas that are large enough, and are compatible with
    the PRIMARY/LOGICAL property of the partition, are suitable.

    The partition tables and LVM-information when present, will be
    updated to reflect the new position.

    When the partition is a bootable one (ACTIVE), the new partition
    created in the freespace area will be made bootable as well.

    MOVE/COPY of a partition that is part of a multi-partition
    LVM volume is NOT supported yet! In that case the menu
    items related to MOVE/COPY will be disabled!

Clone Disk to Disk ...

From main menu: Actions -> Clone Disk to Disk ...

Clone a to-be-selected Disk to another to-be-selected Disk (copy whole disk)

Menu item screenshot(s)


    Cloning will make a sector-by-sector exact copy from one Disk
    to another one. The size to be copied is the lesser of both and
    it is advised to clone TO a Disk of the same or larger size.

    The WHOLE disk CONTENTS is copied, including LVM-information
    and partition-table sectors (MBR/EBR).

    When BAD-sectors are encountered, DFSee will RETRY this buffer
    with single-sector granularity, resulting in the maximum number
    of readable/clones sectors, at the COST of rather SLOW speed.

Clone Partition to other P ...

From main menu: Actions -> Clone Partition to other P ...

Clone a to-be-selected Partition to another to-be-selected Partition, backup

Menu item screenshot(s)


    Cloning will make a sector-by-sector exact copy from one Partition
    to another one. The size to be copied is the lesser of both and
    it is advised to clone TO a Partition of the same size.

    Only the partition CONTENTS is copied, related sectors like LVM
    or partition-table sectors (EBR) are NOT part of the clone.

    Cloning partitions is an excellent way to make a BACKUP of important
    partitions (like your system boot partition) since it can be restored
    quickly in case of problems with the original (after viruses etc).
