Major update: version 5.16

Starting from version 5.16 the software now preserves file creation and file modification dates from original file system as well as from virtually reconstructed file system after data recovery scan.
These dates also appeared in file system object properties dialog as object attributes.
 
In Professional Recovery software edition there are implemented as standard few additional RAID configurations:
 

RAID 1E - "shifted stripe" configuration

 
 
1. Sample of RAID 1E pattern with "shifted stripe" on 5 disks

 
This configuration has 1 drive of guaranteed redundancy and can be built using 3 disks and more.
 
 
RAID 1E - "running mirror" configuration
 
 
2. Sample of RAID 1E pattern with "running mirror" on 5 disks
 


The configuration has the same properties like RAID 1E "shifted stripe", however has different data allocation strategy. For even number of drives the configuration can be considered as similar to RAID 10 by structure and properties.
 

RAID 6 with compact right-asymmetric parity rotation

 

3. Sample of RAID 6 with compact right-asymmetric rotation on 5 disks
 
This configuration is now supported with both P->Q and Q->P redundancy order and different kinds of indexes assignment for Reed-Solomon code for data recovery with 2 missing drives.
 
Among other useful features there are:
  • Support of "capitalization" attribute for 8.3 DOS file names;
  • In-place editor for RAID Definition Language (RDL) in UFS Explorer Professional Recovery.
 
This update is considered as recommended for data recovery and forensics specialists
