R-Studio for Mac 7.0.7009 Wed Mar 30, 2022
New features:
+ Several disk objects can be opened in one tab. All these objects can be simultaneously searched for files, their files can be marked and recovered.
+ Drive imaging can be interrupted and then resumed. When the user stops an imaging process, they have two options: to discard an already created partial image file or to save it to resume drive imaging later. Created partial images can be loaded, too.
+ Some extended options have been added to the drive operation progress windows. They can be altered on-the-fly.
+ File types can be searched for on the Known File Types dialog box.
+ Support for the VMDK virtual disk format (open: all version, creation: Technician).
+ Support for the ReFS 3.7 file system (Windows Server 2022).

R-Studio Technician:
+ A new license type T80+. R-Studio T80+ is equal in its features to full-fledged R-Studio Technician, runs for a certain period of time, and during its validity period can be upgraded to R-Studio Technician for the initial price difference. The license price of 1 USD per day is very affordable for small businesses, computer repair shops, and individual data recovery contractors.
+ R-Studio Technician is now available on our public web pages and can be tested in the Demo mode.
+ Runtime imaging. R-Studio creates drive images in parallel with other drive reading operations. Next time when R-Studio accesses data from imaged drive areas it gets the data from the runtime image.
+ Multi-pass imaging. Images from problematic drives can be created through several phases reading data from good areas first and from bad and slow areas later. Such approach allows for extracting maximum possible amount of data even from quite faulty drives.
+ Support for sector maps, both in the R-Studio's format and in the third-party software ddrescue and HDDSuperClone formats.
+ I/O Monitor allows the user to inspect read/write operations in real time.

* Read operations has been accelerated for block RAIDs by paralleling I/O operations for parent disks. E.g.,the read speed for a 3HD RAID5 has been increased from 100MB/sec to 190MB/sec.
* When a user opens an already opened partition it brings the user to the corresponding tab.
* Option processing for the Find/Mark dialog box has been improved.

- R-Studio may have sometimes failed to find NTFS partitions without boot records. Fixed.
- File previewer didn't correctly display filenames with right to left scripts. Fixed.

A lot of symlink processing bugs have been fixed, two being worst:
- If there was a symlink to another folder in a place to store recovered files, and there was a folder in the data for recovery which name coincided with that symlink's folder, the recovered data was written to the symlink's folder. That may have resulted in complete loss of files stored in the symlink's folder. Fixed. Now R-Studio saves recovered files only within the path(s) specified for storing recovered files.
- When files were marked and then umarked in a folder that was a symlink, the files in its target were unmarked, too. Fixed.
- Disс information wasn't renewed when the CD was ejected and the Refresh command was executed. Fixed.

R-Studio for Mac 3.0 Build 1448 Jun 16, 2012
New features:
+ Simultaneous image creation and scan. Now R-Studio can create an image and simultaneously scan the data being copied. In this case R-Studio creates two files stored at the same place: an image file and file with the scan info.
+ File Recovery Lists: lists of files found on disks that can be exported out of R-Studio, manually edited, than imported back, and files from those lists will be automatically marked for recovery. Such lists are very useful if you want someone who is far away to decide which files are to recover and which aren’t to.
+ RAID consistency check: you may check whether the parity blocks on a RAID are valid.
+ Image and scan info files may be saved on and load from, remote computers. This helps R-Studio to avoid transferring large data volumes over network during network recovery.
