UFS Explorer is updated to version 5.5 and gets more useful features. The update is considered as "regular" and thus it is free for all users of previous 5.x versions. New software release is available for download from download section of UFS Explorer web site.
What's new in this update
Windows logical volumes
Starting version 5.5 software recognizes and displays Windows logical volumes for simplified and alternative representation of locally mounted drives. It keeps showing classic disk/partition structure, but extends it with new group containing only Windows logical drives. This makes logical drive identification easier and allows to access data on dynamic disks (software RAID) immediately.
If you do not need this feature, you may easily turn it off for faster software startup.
Automated RAID Reconstruction
In this release it was added support of fully automated RAID reconstruction, including support of complex RAID-on-RAID configuration. Software will now detect known RAID configurations and build RAID automatically just after software start. The feature supports both complete and incomplete RAID with redundancy, running them in "degraded" mode.
It keeps monitoring RAID components and if missing part of "degraded" RAID will appear, software automatically adjusts RAID configuration to include missing component.
Want to build RAID degraded? Software will not modify RAID configurations created by the user.
Faster RAID operations
Total rework of RAID subsystem introduces much faster data access in "asynchronous mode". This allows to speed-up access on "striped" RAID (such as RAID 0, RAID 5, RAID 6, RAID 3 etc.) by several times for storage scan and data extraction purposes. This mode allows to speed-up even "degraded" RAID operations and scan RAID 5 or RAID 6 with missing drives much faster than single drive.
Adaptive RAID Recovery
Both classic synchronous and new asynchronous data access modes now support automated adaptive data recovery feature. If one or more RAID components contain bad blocks software may read only good data and adjust on-the-fly data access strategy to reconstruct missing information using redundancy. This function supports major redundancy methods, including mirroring, parity and Reed-Solomon code.
More RAID modes
The software now natively supports more possible RAID configurations (mainly related to RAID 6 and "vertical" data distributions: RAID 3/4, RAID 6/Vertical XOR etc.). New configurations support faster operation and adaptive recovery. Introduced RAID 1 support allows to use its redundancy to override bad blocks or even run it in asynchronous mode at same speeds as fast asynchronous RAID 0 by applying adaptive re-striping.
Full disk encryption support
Professional Recovery software edition now gets decryption module with support of major types of full-disk encryption algorithms and methods (such AES/AES256 with CBC and different Initialization Vector modes, including null, plain, ESSIV etc.). In case encryption key is known or can be recovered, software will be able to decrypt the volume (including RAID volumes) on-the-fly and thus access the data or recover lost or deleted files.
Decryption module is compatible to Linux device mapper encryption module (dm-crypt) and can be used with encrypted storages (including NAS storages) if encryption key is known.
