DFSee 14.5 has been released

Saturday June 24, 2017  By: Jan van Wijk

DFSee version 14.5 has been released.

MINOR release, meaning you get it for FREE if you have a 14.x key already.
However, thare are some pretty MAJOR new features and bug fixes:

- Support for disks over 2 TiB, both 512 and 4096 bps (advanced format)
This has been tested on Windows XP, W7, W10, Linux Suse Leap 42.1,
Linux Ubuntu and Mac-OS. It should work on DOS when the BIOS has
support for Extended-Int13 and LBA48 sector addressing (untested).
Unfortunately this does NOT work at all for OS/2 (or eCS / ArcaOS)
due to limitations in the kernel (CHS interface, 16-bit cylinders)

To achieve this, many of the existing display layouts have been
reworked to handle 64-bit sectornumbers and sizes gracefully.

- Support for larger compression units (buffers) in IMZ images.
This can be more efficient in compression, and reduces the size
of the index file that is used for browsing such an image.
The image dialog has been enhanced with buffersize selection.

- Fixes for spurious CRC-errors on verify, and data corruption on restore
for large IMZ images. Users that rely on DFSee images as a backup, are
STRONGLY advised to upgrade to this version for maximum reliability!
On CREATE each buffer is verified by decompressing and CRC-checking.

- Two new desktop program-object for the Windows and OS/2 installer:
- 'Browse IMZ imagefile' to access and browse a disk/partition image
- 'HEX edit binary file' to start an HEX-edit session for a file
Both will present an Open-File dialog where a file can be selected.

- Much better progress reporting for 'SMART' imaging and cloning.
This uses the distribution of unused disk space, as supplied by the
ALLOC display, which now takes a '-b' buffer option for a reliable
prediction of the percentage of sectors to be 'SMART' skipped.

- Support mouse 'doubleclick-to-execute' in the file-pane of Filedialogs
as well as the Browser, allowing the 'single-click' to select only.
(avoids unfriendly 'unexpected sudden completion' of the dialog :)


DFSee is a very powerful disk-utility with disk partitioning,
smart imaging or cloning of partitions or complete disks,
filesystem and disk analysis, directory/file browsing with
edit/view/copy capabilities including limited UNDELETE.

Functional changes since 14.4

- Added 'DISKUTIL' as trusted command for Mac OSX (to unmount disks)
- ALLOC: Predict smart-usage for better ETA in later imaging/cloning
- ALLOC: display: show disk/part-ID/Drive being checked in status bar
- ALLOC: Signal Smart-use info not available when aborting display
- ALLOC: When single-line, output per character (acts as progress bar)
- Allow external commands on any OS (file-redirect, or pipe on OS/2)
- BROWSE/IMAGE new compact index-file formats allowing objects > 2TB
- BROWSE: Fixed renaming of directories from dialog popup (HPFS/JFS)
- BROWSE: Mouse CLICK to select, DBLCLK to enter (subdir or menu)
- BROWSE: Support large (2MiB, DOS 256 KiB) buffers in IMZ browsing
- CLONE (smart): Better ETA using allocation-info for FS or whole disk
- CLONE: Hint at 'compare' fail, on partition clone and auto 'fixpbr'
- Calculated Geometry (geocalc): Force 64/32 1-MiB geo on GPT disks
- CR: Symbolic name 'EXT' = 0x83, 'CONT' = 0x05 (extended container)
- DARWIN: Use faster 'rdiskN' devices, not 'diskN', unless -raw- switch
- DESKTOP folder OS2/Windows: Program object 'Browse IMZ imagefile'
- DESKTOP folder OS2/Windows: Program object 'HEX edit binary file'

- More 64-bit updates, most display layouts accomodate up to 511 TiB
- NEWMBR: Reread diskinfo before 'newmbr' for up-to-date part count
- Opt -b or -b:track sets tracksize as buffersize, -b:N other values
