Mode=HPFS Menu: [OS/2 and eCS High Performance File System]

Allocation map display

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

Display/Edit the standard 11-character label located in the bootsector

Menu item screenshot(s)


    This will present a small dialog to display and/or edit the
    standard (DIR) label, with a maximum length of 11-characters
    and located in the BOOTSECTOR

    This standard label is used to identify the filesystem in
    commands like DIR and FORMAT

Set Volume Serial Number

From main menu: Mode=HPFS -> Set Volume Serial Number

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, no I13X check

From main menu: Mode=HPFS -> Fix Bootsector, no I13X check

Fix bootsector; No explicit I13X check, works with bootmanagers like GRUB


    This will create a new HPFS bootsector for the partition, based on
    information from the partition-tables and on information found in
    the superblock and spareblock for the filesystem.

    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.

    There will be NO explicit I13X check in the bootcode, which will
    allow booting beyond cylinder 1024 even with MBR bootcode that is
    NOT I13X aware (Windows, Linux) and other bootmanagers than IBM's
    like Linux GRUB or LILO, Acronis OS selector and many more.

Fix HiddenSectors/Geo value

From main menu: Mode=HPFS -> Fix HiddenSectors/Geo value

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 bad sectors

From main menu: Mode=HPFS -> Reset bad sectors

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.

Set HPFS status Clean

From main menu: Mode=HPFS -> Set HPFS status Clean

Update spareblock status flags to indicate filesystem is CLEAN


    This will update the fileystem-status field in the HPFS spareblock
    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.

Set HPFS status Dirty

From main menu: Mode=HPFS -> Set HPFS status Dirty

Update spareblock status flags to indicate filesystem is DIRTY


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

    This can be useful to force a CHKDSK operation on the next boot.

    Note: The filesystem itself is NOT affected in any other way, it is
    just the statusflag that is modified.

Display Superblock

From main menu: Mode=HPFS -> 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.

Analyse HPFS filesystem

From main menu: Mode=HPFS -> Analyse HPFS filesystem

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.

Reselect whole disk, FDISK

From main menu: Mode=HPFS -> 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
