v9.0 [Jan 29, 2022]
- Native support for data recovery hardware from DeepSpar: USB Stabilizer and RapidSpar. Such support allows the user of R-Studio to control hardware parameters directly from the R-Studio interface and create drive's sector maps to improve multiple data recovery operations. (R-Studio Technician)
- 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. (R-Studio Technician)
- 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. (R-Studio Technician)
- I/O Monitor allows the user to inspect read/write operations in real time. (R-Studio Technician)
- Support for sector maps, both in the R-Studio's format and in the third-party software ddrescue and HDDSuperClone formats. (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.
- 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.
v8.9 [Dec 17, 2018]

- R-Studio sometimes couldn’t select a file system to scan. Fixed.
R-Studio 7.5.156211 Thu Oct 16, 2014
New features:
Support for Windows Storage Spaces created by Windows 10. Now R-Studio can process WSS created by Windows 8/8.1 and 10, both with automatic recognition and manual adding their parents.
Support for software Apple RAIDs created by the Mac OSX system. R-Studio can automatically recognize and assemble them from their members. Members with severe corrupted RAID parameter records can be added manually.
Support for Linux Logical Volume Manager (LVM/LVM2). R-Studio can automatically recognize and assemble its volumes from their components even if RAID parameter records are slightly damaged. Components with severe corrupted RAID parameter records can be added manually.
v7.3 [Aug 10, 2014]
Features:
- Support for Windows Storage Spaces. R-Studio can automatically recognize and assemble Windows Storage Spaces from their parents even if their databases are slightly damaged. Their parents with severe corrupted storage pool databases can be added manually.
- Support for DiskSpare Disk Imager (DDI) images and disk maps. R-Studio can read and process images and disk maps created by standalone DDI hardware.
Improvements:
- When recovering data over network, R-Studio now processes virtual block RAIDs, as other objects, on the remote side, avoiding large data transfers over the network.
- R-Studio Demo can recover files up to 256 KB.
- The scanning stop procedure is improved: scan information can be saved before stopping.
Bugfixes:
- Sometimes R-Studio might cut recognized partitions on virtual RAIDs.
- R-Studio might incorrectly found places on disks where deleted files/folders were placed if their MFT records were overwritten by new files/folders.
- S.M.A.R.T. info for new disks might be detected incorrectly.
- File search for cyclic simlinks might work incorrectly.
v7.0 [Sep 20, 2013]
- automatic RAID parameter recognition.R-Studio can recognize all RAID parameters for RAID 5 and 6. This feature helps the user to solve one of the most difficult problems in RAID recovery.
- it support for parity delays in all applicable RAID layouts.
- enhanced parity delay controls.
v6.0 [Jun 7, 2012]
Simultaneous image creation and scan. Now R-Studio can create an image and, at the same time, scan the data from the image. As a result, two files are created at the same place: an image file and file with the scan info.
File Recovery Lists: lists of files from 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.
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.
v5.4 [May 4, 2011]
- NAT/firewall traversal. A connection can be established either from R-Studio to R-Studio Agent, or from R-Studio Agent to R-Studio. This allows R-Studio to traverse NAT/firewall when recovering data over the Internet. HTTP tunneling is used when necessary.
- Scan algorithm improvement. Scanning was improved for FAT and NTFS partitions.
In-place saving of recovered files on a remote computer. When recovering data on a remote computer over network, R-Studio can now save recovered files to another disk of the same remote computer-to an external USB hard drive, for example. Moreover, the remote computer can be connected to the Internet rather than to a local network. This feature is especially useful for data recovery technicians and corporations, which can now serve their clients truly remotely over the Internet and do not need to transfer large volumes of data over network. In addition, files recovered from a remote computer can be saved to a local computer or on another remote computer with an Internet connection where R-Studio Agent is running.
- Forensic mode (Technician version only). In this mode, R-Studio generates a forensic data collection audit log that can be presented at court hearings. This log includes information about a hardware configuration on which the forensic data collection takes place and MD5 checksum for recovered files.
- RAID 6 support, including Reed-Solomon and Vertical XOR. Support for custom-specified RAID 6 layouts.
- Support for exFAT and Ext4 FS file systems.
- Advanced object copy. In addition to byte to byte copy of any object visible in the Drives panel, smart copy of partitions and hard drives with size and offset adjustment is available.
- Progress bar. It shows the progress for an individual file being recovered and overall recovery process, elapsed and remaining time, and recovery log.
