R-Studio 9.4.191301/191303 Wed Apr 10, 2024
New features
+ 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.

* Information about saving system info and for times of recovery list export has been added to the Log.

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.

+ R-Studio Technician: Integration with DeepSpar Disk Imager, a professional HDD imaging device specifically built for data recovery from hard drives with hardware issues. Such integration provides R-Studio with a low-level fine-tuned access to drives with a certain level of hardware malfunction. Moreover, it allows disk imaging and analyzing be performed simultaneously. That is, any sector R-Studio accesses on the source disk will be immediately copied to a clone disk and any other data recovery operation will be made from that clone disk avoiding further deterioration of the source disk and great reduction in processing time. Read more on Integration with Hard Drive Recovery Hardware.

R-Studio 6.0 Build 151275 Thu Jun 07, 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.

- The Device Property Tab might not always show correct values when an element was changed in Property View. Fixed.
- Values in Property View might not be shown correctly. Fixed.
- The Wait dialog box might sometimes truncate long strings. Fixed.
- The Recover dialog box might incorrectly show file paths for saved files during network recovery. Fixed.

R-Studio 5.4 build 134372 Nov 08, 2011
* Now it’s possible to edit a disk with 2^63 sectors (previously it was 2^32).

- If a single address without a mask was specified on the Connect dialog box, the Wait button was grayed out. Fixed.
