What's new in version 9.9:

 

• Added 'activity monitor' tool to display the activity of the software instance with disks;
  
• iSCSI support:
  - Initiator (client) now doesn't require multi-host/cluster mode and works on single connection;
  - The Target (server): fixed several network communication issues;
  
• Microsoft Storage Pools (Storage Spaces):
  - Added support of 'Parity of mirrors' internal configurations;
  - Added support of 'Three-way mirror' configurations (when the number of components is a multiple of three);
  - Basic support of so-called 'dual parity' on Windows Server 2012R2 (also with adaptive reconstruction with single missing);
  - Fixed bug with 'Two-way mirror' (in span, not rotation mode), created on Windows Server 2016 and later;
  
• When image file has associated map of defects, added automatic recognition of presence of that map:
  - Software asks to load associated 'Attr.map' for 'TaskImage.bin' when it is present in the same folder;
  - Added support of saving of map association to image files in VHDX format and software asks to load the map if the file is found;
  
• Software now uses 'storage with map' icon for 'defects recognition' and SDLSP with enabled internal map of block states;
  
• Linux software version:
  - Addes support of indication of OwnerID/GroupID for Btrfs, EXT2-4, UFS1-2, XFS and ZFS;
  - OwnerID/GroupID is also preserved for scan results of these file systems;
  - OwnerID/GroupID can also be preserved when data is copied (when copying of 'standard' attributes is enabled);
  - Fixed one scenario of GUI-related crash bug;
  
• Fixed few bugs related to XFS file system scan;
  
• Updated HFS+ scan procedure to support file system recovery when main metadata locations are wiped;
  
• Updated Btrfs file system scan procedure for finding fragments of very fragmented deleted files;
  
• Fixed issues with support of text LVM configurations created by CentOS 8.

What's new in version 9.8:

 

• Added tool and tab for displaying of a map of block states (defects) applied to a storage;
  
• Map of block states is now integrated with Explorer and with the 'Go to content'/'Go to descriptor' tools;
  
• Added 'View map of file' function (displays the imaging status of a specific file);
  
• Information about defect blocks, recognized by a pattern now can be saved (cached) to a map file;
  
• Loading of maps of sector states (defective sectors):
  - For maps in the ACE Lab format, added automatic section of sector size using the map size to drive size ratio;
  - When the ACE Lab RAW map format is selected, software now also recognizes the range-based format (to avoid mistakes);
  - For drives with DDI metadata: added an option to enable an external map of defective blocks;
  
• Block state information is now also passed to 'sub-range', 'transformed' and RAID0/RAID1/JBOD storages;
  
• Fixed bug with scan of chunks on VMFS6;
  
• SDLSP and VHDX image file formats now preserve information about the source storage (name and ID);
  
• Date/time entry fields replaced with the date/time selection dialog;
  
• In hex viewer, the 'hex search' function:
  - Added a function to pause it to release the source storage for other operations;
  - When stopped, the last searched position is stored as 'Next location' to allow a jump to it;
  
• NTFS file system: fixed issue with support of very fragmented files when the FileName attribute is outside of the main MFT entry;
  
• Fixed bugs with creation of big VHDX files (over 4TB);
  
• General modifications of maps of block states/defects:
  - Native 'sdmf' map format is changed to the "sparse" format for better speed and lower storage usage;
  - Reworked internal functions of the disk imager tool to support the sparse format;
  - Information about the source storage is now saved to a map and is displayed when the map is loaded;
  
• SDLSP and VHDX image file formats now preserve information about the source storage (name and ID).

What's new in version 9.7:

 

• Linux LVM recovery module:
  - Added 'address translation' of found text configurations to the base storage;
  - Found text configuration now can be displayed with embedded viewer;
  
• Added basic support of LVM thin-provisioned volumes (Linux only) via 'Find LVM' tool;
  
• In Disk imager:
  - Added option to shut down the source after completion (when power control is available);
  - 'Entry name' field for EnCase format now can be customized (by default is the same as file name);
  
• Reworked operations with defect maps:
  - Updated 'map loader' GUI (more obvious configuration, added map preview function);
  - Software now enables file-based maps (when possible) to speed up loading and reduce memory usage;
  - New type of storage object with applied map now supports indication of imaged/defect/free spaces;
  
• Fixed some reported bugs/issues:
  - In hex viewer: incorrect base position for 'big block search', loss of colorer function for cached data;
  - File system module: silent crash bug with bad F2FS;
  - Handling of soft-defect blocks: extending of file map to whole block in scan result;
  - LUKS decryption: using of SHA512 for hash function caused problems with decryption;
  - Some minor GUI-related issues (under Windows OS).

What's new in version 9.6:

 

• Updated function of opening LVM thin-provisioned volumes:
  - Added interface to choose from volumes, defined in text configuration;
  - Support of QNAP thin volumes implemented via Tier/Thin technology (tiering is not supported);
  - Support of segmentation for thin-provisioned volumes;
  - Opened volume now contains proper LVM ID, name and Unix-path;
  
• Added support of WD Apollo 'cloud storage';
  
• Added activity monitor for DeepSpar USB Stabilizer/Guardonix;
  
• USB Stabilizer/Guardonix configuration: added option for 'Auto-repower by UFS Explorer';
  
• Disk imaging with DeepSpar USB Stabilizer:
  - Added explicit configuration of re-power options for read timeout and read errors;
  - Error recovery after 'storage loss' now includes re-power cycle;
  
• General disk imaging:
  - Fixed issue with handling error of creation of plain disk image file;
  - Fixed support of 4GB image chunk size on FAT32 target file system;
  
• Restoration of file/folder attributes (hidden flag, permissions etc.) was made optional;
  
• Mac software version now comes with native Apple Silicon CPU support and requires macOS 10.15 or later.
