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.
Submenu to search for deleted/normal files, list and possibly recover them
This submenu offers selections to search for normal or deleted
files, display the resulting lists and possibly recover files.
Search for FNODEs for deleted files, 'Recover from list' will UNDELETE them
This will search the whole partition for file FNODEs that belong to
DELETED files, and that match the start of the filename specified.
The sectornumbers of the found FNODEs will be added to the DFSee
sectorlist so can be used in later actions, or be exported to a file.
The files contained in that list can be RECOVERED to any directory
on the system, including a network, by using the 'RECOVER' command.
Search for FNODEs for deleted or non-deleted files, for 'Recover from list'
This will search the whole partition for file FNODEs of non-deleted
or deleted files that match the start of the filename specified.
The sectornumbers of the found FNODEs will be added to the DFSee
sectorlist so can be used in later actions, or be exported to a file.
The files contained in that list can be RECOVERED to any directory
on the system, including a network, by using the 'RECOVER' command.
Search data area for FNODEs for non-deleted files, for 'Recover from list'
This will search the whole partition for file FNODEs of non-deleted
regular files and match the start of the filename specified.
The sectornumbers of the found FNODEs will be added to the DFSee
sectorlist so can be used in later actions, or be exported to a file.
The files contained in that list can be RECOVERED to any directory
on the system, including a network, by using the 'RECOVER' command.
Display (selected) files from the list, using a PATH+FILENAME wildcard
This will display the DFSee sector-list in a compact format, suited
to the data contained in the list
This usually is a 'list -f' or a 'list -s' variant.
Recover (selected) files from the list to a supplied recovery directory
This will allow you to recover (copy) one or more of the files in the
list to any local or network directory on your system.
It will prompt for a destination directory first, using the last used
one as a default. All files recovered in one go, will be recovered to
this same directory, with their original path appended to retain the
directory structure whenever possible.
It will also prompt for a selection specification in the form of a
full PATH+FILENAME wildcard and an optional allocation-percentage.
As an example, the specification:
'*mydoc*\*project_x*.doc%100'
will recover all files that have 'mydoc' somewhere in the PATH,
'project_x' in the filename and have an extension of '.doc' that
seem to be 100% recoverable. (100% allocation-OK ranking).
Recover the file associated with the CURRENT sector to a recovery directory
This will allow you to recover (copy) the file represented by the
CURRENT displayed sector, also called the 'THIS' sector to any local
or network directory on your system.
It will prompt for a destination directory first, using the last used
one as a default. The file will be recovered with its original path
appended to that to retain the directory structure whenever possible.
The menu item will only be enabled (selectable) when the CURRENT sector
represents a normal or deleted FILE for the filesystem involved.
This means it has to be a type 'f' or 'z' sector, which is:
For HPFS: an FNODE sector
For JFS: an INODE sector
For NTFS: an MFT record
Fix bootsector, HiddenSectors/GEO, and HPFS LDR imaging and fixing
This submenu offers selections for fixes related to booting like
fix the bootsector itself, HPFS LDR image creation and restore
and fixing the HiddenSectors and geometry fields in the bootsector
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 bootsector; Use explicit I13X check, requires I13X capable MBR and BMGR!
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 an explicit I13X check in the bootcode, which will
require an I13X capable MBR (from IBM or DFSee) as well as an I13X
capable (IBM) BootManager like the LVM, eCS or DFSee ones.
Create compressed imagefile with the HPFS LDR sectors for this partition
This will create a compressed imagefile with the HPFS LDR sectors
from the current HPFS partition, to be used later for a restore to
a damaged system.
Restore imagefile with a 'known good' HPFS LDR to current partition
This will restore an imagefile with the HPFS LDR sectors to the
current HPFS partition.
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!
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.
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
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.
Find detailed info (FNODE/MFT-record) for the specified file/directory path
This uses the specified path from the root-directory to locate
detailed information for the file or directory for that path.
This will be from the FNODE on HPFS, the MFT-record on NTFS or
similar structures like Inodes on other filesystrems.
The path and filename may contain spaces.
When found the information will be displayed in the standard
format as defined for the filesystem that is active.
You can display related information like the directory entry
or the actual file data from there using the U and D commands.
Find and Fix some of the HPFS specific filesystem structures
This submenu offers selections for fixes related to the HPFS
filesystem structures like the super and spareblock, codepage
information and so on ...
Find the sector containing the FNODE for the root directory
This will search the whole partition until FNODEs are found that
can be used to determine the path and location of the HPFS root-
directory.
This might be useful on heavily damaged HPFS partitions to get
access to (part of) the file and directory structures again.
The found location will be used by the 'Fix superblock values'
menu selection automatically.
Update superblock using found rootdirectory location and partition-info
This will recreate the HPFS superblock using information from the
partition-tables and a newly found root-directory.
It will try to find the most relevant data-structures referenced
from the superblock, and update the checksum value too.
Find the sector containing the codepage information and data
This will search the start of the partition for CODEPAGE information
or data sectors
This might be useful on heavily damaged HPFS partitions to get
correctly interpreted filenames again.
The found location will be used by the 'Fix spareblock values'
menu selection automatically.
Update spareblock using found codepage LSN and superblock values
This will recreate the HPFS spareblock using information from the
partition-tables, the superblock and newly found CODEPAGE info.
It will try to find other relevant data-structures referenced
from the spareblock, and update the checksum values too.
Make the currently selected PRIMARY the 'active' partition for MBR/BIOS boot
This will make the currently selected PRIMARY partition the
ACTIVE one for the disk.
There should only be a single active partition on every disk.
When the system starts, the BIOS will usually boot from
the ACTIVE partition on the first disk.
In IBM BMGR/LVM terms the active partition is called STARTABLE.
Delete the currently selected partition from the partition tables
This will delete the partition that is currently selected to be
deleted from the partition-tables. This will result in the space
occupied by the partition becoming FREESPACE that can be used
again to create new partitions.
For primary partitions on LVM-systems, the related LVM-information
is cleared as well, to avoid consistency problems later when a new
partition is created at the same position.
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.
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.
Dump the HPFS super/spare, codepage etc to a file for analysis (support :-)
This will create a binary dump for the start of the filesystem
which will include the superblocks, codpage info and more.
Quite useful for later analysis, perhaps by DFSee support.
The usual IMAGE dialog will be presented, with the startsector
and size filled in, as well as a suggested filename.
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.
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.
Create Sector Lookup Table (SLT) if needed, display as table or sector info
This submenu contains all menu-items related to OPENING an object
to analyse, fix or otherwise work with using other DFSee commands
and menu selections. The opened object will be the CURRENT one.
Show layout of current object by displaying parts of the Sector Lookup Table
This will display part of the sector-lookup-table (SLT)
You wil be presented with an option dialog first, where you
specify the desired format and part of the SLT to be displayed.
The SLT will be built automatically if not done yet, and it will
have been built by any previous CHECK command too.
Building the SLT will take place in the background while the
dialog can be used freely to specify any options for displaying.
After the dialog has been ended, and the SLT is ready, it will
be displayed as requested.
Typically the SLT will contain at least one entry for every file
on the filesystem, so there could be hundreds of thousands lines!
Show identification for specified (or current) sector, using the SLT
This will display information about the specified sector that is
available in the sector lookup table (SLT)
The most useful info is the sector referencing this sector, this
often leads to showing to which file/directory the sector belongs.
The SLT will be generated automatically if not yet available
Show identification for the last sector used, dictating the minimum FS size
This will display information about the sector that is the last
one being used (allocated) in the filesystem, and because of that
dictates the MINIMUM size for the filesystem for a RESIZE.
The most useful info is the sector referencing this sector, this
often leads to showing to which file/directory the sector belongs.
The SLT will be generated automatically if not yet available,
just as the required allocation information (alloc).
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
