What's new in version 9.15:

* In the 'Open thin-provisioned volume' tool:
- Added a function to open a volume in case of partial metadata damage ('ignore errors' mode);
- Added support of 'thick' volumes (with pre-allocated space);
* In the general storage decryption dialog: added support of constant initialization vector;
* Some optimizations of GUI for default (double-click) actions (to decrypt encrypted storages etc.);
* Some optimizations of 'Drives/Bridges security' tool (to speed-up detection, get rid of unnecessary volume unmounts etc.);
* RAID5 and RAID6: added an option to generate virtual defect blocks explicitly instead of using pattern fill (to sort good/bad files basing on defects);
* RAID builder GUI:
- Added support of RAID50 and RAID60 as separate RAID types;
- Pattern display grid is also adopted to RAID50 / RAID60;
- Added a configuration parameter for virtual reproduction of defect blocks on over-degraded areas (RAID levels 5, 6, 50 and 60);
- Added stripe of size 512 bytes to the stripe size selection list;
* Drobo RAID: added bitmap support for cache, fixed bug with adaptive RAID reconstruction;
* Added support of direct access to SMART/identification of NVMe storages on USB adaptors with Realtek, Asmedia and JMicron bridge chips;
* Under Linux: added support of direct access to NVMe SMART/identification information;
* In SMART monitor:
- NVMe: added indication of maximum (warning) temperature and current TBW (terabytes written) basing on NVMe SMART;
- SAS: added displaying of G-list size for SSD; also added TBW estimation (both SSD and HDD), basing on Log Page 02h information (WRITE log);
- SATA SSD: added displaying of TBW estimation using F9h SMART attribute, when available;
* Under Windows: added system (OS) file cache size to software settings - to control system memory use when working with image files;
* Few corrections to FAT/FAT32 scan procedure (to support several previously unsupported metadata damages);
* Added support of several recent digital cameras (RAW formats) to embedded viewer.

What's new in version 9.16:

* In disk imaging task (on demand imaging):
- All supported data protection/write-blocker adaptors are now 'recommended' type of source (storage protection from activity of running OS);
- Fixed several bugs (retries, 'source loss' condition etc.);
- Changed default configuration for Tier1 imaging (no extra retries, enabled two-pass imaging);

* Added sharing of 'file type check' information from scan result to filtered scan result;

* Added possibility to enable log file (journal) scan for quick scan of NTFS file system (default is 'off');

* EXT3/4 (In 'quick' scan/indexing): processing of journal is now made optional (default is 'off');

* Intel Optane: reworked cache mapping algorithm and added support of linear (spanned) cache zone;

* RAID50/60 support: Added reverse address translation for RAID builder GUI;

* iSCSI target (server):
- Fixed compatibility issue with open-iscsi client (iscsiadm);
- Added proper reproduction of defect blocks via iSCSI (verified with default Windows initiator and Linux open-iscsi);

* Drobo BeyondRAID: speed-up of general read/scan operations (especially for non-allocated storage space);

* Added support of hardware RAID on JMicron chips (including QNAP TR extension boxes);

* Added recognition/support of certain WiebeTech (CRU) and Tableau (Opentext) data protection bridges/adaptors;

* In the general disk imager (image at once):
- Speed optimization for EWF (E01) image file creation;
- Speed optimization for SDLSP format (especially on a LAN target);

* EXT3/4 file systems:
- Faster (optimized) processing of file system journal - by caching it to memory;
- Faster 'open' for existing big EXT3-4 volumes;

* Fixed issue with support of SATA M.2 SSD via Realtek USB-to-NVMe bridge chip;

* Added support of drives identification and SMART access on IEEE 1394 (FireWire) connection;

* In embedded viewer:
- Added several unsupported camera raw formats (and fixed couple of related bugs);
- Significantly reduced number of access attempts to storage when defect block is detected.

What's new in version 9.17:
  • Added basic function of volume address translation to a file system file/folder and the offset inside;
  • In RAID Builder: added tool to build 'a copy of RAID' - it allows to build several different configurations from the same source;
  • Added support of older 3Ware RAID metadata format for automatic RAID construction;
  • Added support of message activation in file copying message log:
    - Activation of file-related event now opens container folder and selects the associated file;
    - When events are automatically redirected to a file (due to log overflow), activation of redirection event record will open the log file;
  • In disk imager:
    - Changed log format for better compatibility to forensic imaging (also included information about forensic bridge, imaging status etc.);
    - Better handling and indication of image write errors;
  • SMART tool:
    - Refresh operation is made asynchronous to prevent UI from freezing on long updates;
    - Proper indication of SCSI 'not ready' status (including running FORMAT UNIT command);
  • Reworked file copying with replacement of 'unsafe symbols' (such as '/', '?' etc.):
    - Under Windows: unsupported symbols on a source file system are changed to special Unicode symbols (macOS-style) on a target;
    - Under Linux: all 'unsafe symbols', except '/' are now allowed;
    - Under macOS: all 'unsafe symbols', except '/' and ':' are now allowed;
    - When source file system contains macOS Unicode replacement symbols, they are changed to 'original' ones in the user interface;
  • Minor fix to ReFS3 file system (to support a variation of metadata format);
  • Fixed bug with EFS-encrypted files, recovered with full-disk scan stage;
  • Fixed bug scanning volumes with compressed files on NTFS;
  • Fixed bug processing extended attributes on XFS file system;
  • Legacy HFS file system: now displayed and preserved file creation/modification dates.

What's new in version 9.18:
  • Added support of 'data entropy' map:
    - In disk imager, added possibility to save 'data entropy' map during imaging (low and high resolution);
    - Added option for visualization of entropy map during imaging (with synchronization to imaging and to map of defects);
    - Added possibility to visualize saved 'data entropy' map via 'Enable a block status map' tool;
  • In map visualization GUI:
    - Added possibility to change dynamically the size of grid cells;
    - Added support of statistics on 'data entropy' map;
  • In RAID builder:
    - In context menu of selected set, added 'To a new RAID' tool to create a RAID on a subset;
    - Added also comparison of selected items via 'Compare storages' context menu option;
  • Added support of multi-volume configurations of very old Drobo DAS devices;
  • In disk imager:
    - Changed two-pass imaging to multi-pass imaging by adding optional one or two pre-imaging stages (with no retries on defects);
    - Added optional pre-imaging stage 0 - to quickly skips slow and damaged areas for fast imaging of 'healthy' areas;
    - Added one more pre-imaging stage to run on slow areas and to skip areas with defects (postpone them to the 'normal' stage);
    - Added possibility to override number of retries and read timeout for the final imaging stage;
  • Built-in viewer now supports displaying the contents of certain archive file formats:
    - Added support of Zip, TAR, GZip and BZip2 archive container formats (including .tar.gz, .tar.bz2);
    - Added content decompression for Deflate, Deflate64, BZip2, LZX, LZMS, LZMA, MS XPress and plain content streams;
    - Added limited support of Windows IMage (WIM) file format (only individual files in current format);
    - Support of preview of contained files;
  • In 'file search' result: added missing color and file status indication;
  • Added displaying of the number of files in scan result folders;
  • Disabled the indication of the folder metadata size (to avoid confusion with the size of contained files);
    - Added possibility to re-enable this function in the software settings;
  • Fixed issue displaying color progressive (one scan per component) JPEG images as greyscale;
  • Reworked support of ISO9660 file system.

I have a small question???

So i just installed UFS Explorer on My computer. Trying to recover a file just recently deleted
My computer has 2 Bitlocked partitions. That are open in Windows ( Fully accessible)

Isn't UFS Explorer should be able to access those to partitions and scan them???
Upon clicking on those 2 partitions i don't have the option to scan lost files in them.

I have the option to decrypt them either with password or with BEK file. What should the password be??? Windows login password?? Microsoft Password???
Because i've tried all kind of passwords and haven't been able to decrypt them

Can anybody help and explain???

Many Thanks!!!

Click to expand...
It's the bitlocker recovery key. If it was saved to your Microsoft account when you created the key, you should be able to get it from Microsoft on this page: https://account.microsoft.com/devices/recoverykey

Otherwise you are at the mercy of hoping the key was saved somewhere else at the time of creating it.
