R-Studio for Mac 7.4.191348 Fri Jul 26, 2024
New features
Technician/T80+
+ Multitasking. Several different tasks can be performed simultaneously. For example, you can create a multi-pass image using a third-party hardware, scan a disk image, and recover files from another image, all at the same time. The number of concurrently performed tasks depends only on the computer efficiency (CPU, RAM, HDD/SSD, etc). Each task runs in its own tab and can be controlled individually. Computer shutdown takes place when all tasks are completed. The list of running tasks is displayed on the Main panel in the lower left corner.
+ Hidden devices. Devices that are not subject to scanning for data recovery can be hidden from the Main panel (System disks, devices for storing recovered data, etc). Such hidden devices are still accessible for storing recovered files, logs, scan info, etc.
The Technician/T80+ version

Improvements
* Data for Scan Information Details dialog box is now loading faster and can be stopped if it's huge.
* Image display in File Previewer has been improved.
* R-Studio can now use an already existing sector map to continue image creation, even if the drive attributes (its vendor, product name, GUID, or serial number) don't match the image ones. The drive size should always match.
* Information about saving system info and for times of recovery list export has been added to the Log.
* Runtime imaging can be started from the Create image dialog box in the Technician/T80+ versions.
* "Recheck recovery chances" has been improved for existing files.

Changes
= In the R-Studio Standalone and Corporate versions, a running task is now shown in a tab.
= A new layout for the Settings window.
= Detailed, simple, and none scan views have been removed from the Scan dialog box.

Bugfixes
- The program may have frozen during executing the Show Files command to process symlinks on Unix file systems. Fixed.
- When processing files on a remote computer, the program always warned about possible file overwriting, even when there was no such files. Fixed.
- It was impossible to resume image creation if the image file (except for a runtime one) was completed with some skipped sectors failed to read by a timeout. Fixed. It's possible now to resume image creation using multi-pass imaging with the Retrying phase on.
- R-Studio incorrectly processed XFS partitions with 4K sectors. Fixed.
- Folder cross-links were processed incorrectly for XFS file systems for inode numbers larger than 2^32. Fixed.
- Some bitmap files couldn't be identified by using search for Known File Types. Fixed.
- Some files couldn't be recognized by their file signatures when their beginnings looked like a text file and were close to the previous text files. Fixed.
- Valid jpg files were split into two invalid parts when their previews in their exif parts were on the sector boundaries. Fixed.
- The repeated window for password for APFS/ACS didn't appear when a wrong password was entered. Fixed.

- The program confused / and \ (acceptable for file paths on the EXT* file systems) in file path separators when importing recovery file lists. Only / is now used as a path separator in recovery file lists.
- No warning about enabled runtime imaging appeared when R-Studio was closed. Fixed.
- A possible cause for memory leak has been eliminated.
- Several internal bug fixes.
- Several crash causes have been eliminated.

+ 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.

- R-Studio may have crashed when the Recover All Files command was started. Fixed.
- R-Studio may have frozen when a shortcut menu was invoked for an incremental image without one part. Fixed.
- R-Studio parsed only the GPT partition table, even when it was invalid, when both LDM/MBR and LDM/GPT were present on the disk. Fixed.
- The Recover marked command was inactive if marked files were invisible due to the applied file mask. Fixed.
- The Copy information command copied the information from the previous file when the information of the selected file didn't exist. Fixed.
- The Expand All command for the folder tree may have frozen on partitions with large numbers of folders. Fixed.
- The number of marked files may have been displayed incorrectly when the view was changed from Real, by Extension, by Time, etc. 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 tried to access an attached CD/DVD drive during device refresh which may have resulted in temporal freeze. Fixed. Now R-Studio accesses a CD/DVD drive only when it works with it. Fixed.
- R-Studio may have temporally frozen while switching between the Real, Extension, XXX Time views for partitions with many folders. Fixed.
- Many internal bugfixes to improve program's efficiency.
- Some cosmetics bugfixes.
