R-studio Disk Recovery

[Placido Teofilo]

RSTUDIO is a family of powerful, cost-effective disk recovery software. Originally developed by R-Tools Technology, Inc. for experienced data recovery professionals, R-Studio has been redesigned as a scalable, user-friendly all-in-one data recovery tool. By coupling our most advanced file recovery and disk repair technology with an intuitive user-interface, R-Studio provides enterprise and professional-level data recovery specialists the tools they need without hindering the experience of entry-level users.

R-Studio Emergency version is run from a USB stick or compact disc when it is necessary to recover data on a computer, on which operating system cannot start up because its system files are corrupted or deleted.

Check out this special offer for power users and data recovery professionals: the R-Studio Technician package. In addition to the standard R-Studio features, the R-Studio Technician package offers advanced data recovery features, including forensic mode, data recovery over Internet, R-Studio portable, and unrestricted bootable disk. The R-Studio Technician package also includes licensing for the Windows, Macintosh and Linux versions in one single package.

All R-Studio and R-Studio Emergency features and capabilities can be evaluated and tested in the Demo mode. The only limitation the Demo mode has pertains to the maximum size of a file that can be recovered. The software running in the Demo mode can be registered on the fly at any time. No reinstallation is required.

To see how R-Studio can recover data in a specific case, you may download R-Studio free, install it on your computer, and run it in the Demo mode (for a nonbootable machine, an R-Studio Emergency CD/DVD can be created). If you do not have hard drive recovery experience, we advise you to download and read our Data Recovery Manual before you start. You'll find step-by-step instructions and recommendations prepared by our data recovery specialists. For any additional questions you may always contact our technical support team even if you haven't purchased the software license yet. When lost files are found you may recover files with a size of less that 256KB each. Other files, supported by the pre-viewer built in the software, can be previewed to estimate chances for successful file recovery. If you are satisfied with the result, you may purchase an R-Studio license online right away. Upon receiving a registration key, you may register R-Studio on the fly without even closing the program. As soon as R-Studio is registered, you may continue recovering files.

Moreover, using R-Studio in the Demo mode you may create images of your logical disks or entire hard drives. Then you may perform all data recovery actions with those images to keep the source disks safe from accidental data corruption. These images are especially important when you are working with hard drives that start showing signs of dying, to prevent losing data from the drives for good.

R-Studio is our most popular full-featured disk recovery solution for local data recovery. Any laptop or desktop computer running R-Studio becomes a powerful data recovery station, capable of solving even the most challenging data recovery and disk repair tasks faced by experienced IT specialists. R-Studio recovers data from any data storage device (Flash drive, hard disk drive, laptop drives, SD cards, etc.) and works with partitions created by every major operating system (Windows, Linux, Mac, Unix). For local disk recovery, R-Studio can read/write, analyze, and image disks and sectors via an IDE/SATA connection or through USB, e-SATA, or FireWire adapters.

In addition to all file recovery features available in R-Studio local versions, R-Studio network products (in versions for both the Windows and Macintosh-based platforms) offer users access to remote computers and data recovery over the network. This feature is very useful when it is necessary to provide system or network administrators with control and efficiency in file recovery over a TCP/IP connection in a network of a couple or thousands of computers with the flexibility and ease of a single machine.

It also may be useful when it is necessary to recover data when there is no direct access to a hard drive with the lost files (for example, a corporate network server with an advanced RAID controller).

R-Studio Agent and R-Studio Agent Emergency are the service programs that give R-Studio network access to disks on a remote computer. The service program must be installed and/or run on the victim computer, whereas R-Studio is installed and run on another computer, a system administrator workstation, or a workstation dedicated to data recovery. All data transmitted over a network is encrypted with a strong algorithm (3DES) for data security. R-Studio and R-Studio Agent do not pump gigabytes of data over the network to analyze them. R-Studio Agent does the actual data analysis on the computer where it runs and sends only the information on the data to its mother R-Studio.

If the OS cannot recognize your RAID, you can create a virtual RAID from its components. Such virtual RAID can be processed like a real one. Standard RAID levels supported: 0, 1, 4, 5, 6. Nested and non-standard RAID level supported: 10(1+0), 1E, 5E, 5EE, 6E. Support for parity delays in all applicable levels. Support for customer-specified RAID layouts.

All R-Studio versions create IMAGE FILES for an entire Hard Disk, Partition or its part. Such image files can be compressed and split into several files to put it on CD/DVD/flash or FAT16/FAT32/exFAT. Then the image files can be processed like regular disks.

The advanced multi-pass disk imaging algorithm with variable parameters and runtime imaging added to R-Studio Technician make it the ideal complete solution for creating a professional data recovery workstation.

The files and directories on one of my ntfs partition were wiped out last time. I used R-studio to scan the partition, and it did find many files, actually more than the capacity of the partition. This is because R-studio found files that were deleted even earlier. So I wonder if it is possible to specify those files and directories deleted last time instead of those deleted earlier for recovery?

R-studio has a free demo version, for which scanning is free,but recovery isn't. It is downloadable from -recovery-software.net/Data_Recovery_Download.shtmlIts manual is here -tt.com/downloads/Recovery_Manual.pdf. I have tried my best to search for answers in the manual, but failed to find one. Their technical support is not as good as their software, and helpless usually in my opinion.

What happens is that R-Studio examined the file-system (in the case of your NTFS disk, the MFT and saw a bunch of files that have been marked as deleted (their names are still there, but the system put a special flag on them indicating that they are deleted and the space they occupied is available for new files to use). When you write new files, they may overwrite the clusters that deleted files had previously used, but the new files will usually get their own, new entry in the MFT instead of overwriting the old ones (up until a point, then either the MFT gets expanded to make more room, or very old entries get reused, depending on your configuration).

As a result, when a program looks directly at the MFT, it may see a list of many old files that have been deleted a long time ago (which when added up will, can of course be larger than the total size of the disk). However this does not mean that you can recover them because the MFT is basically just a list of files that exist or have existed on the system; the actual contents of the files are stored on disk and once they are deleted, they may be overwritten by new files.

This is not as big of a problem if you have plenty of free space because the system may use space that has never been used before, but eventually, it will start reusing clusters that used to belong to files. Worse, when the drive gets full (like it was in your case with 97% full), the system will overwrite clusters from deleted files.

Got it. I will definitely try R-Linux.

But I already managed to try Hetman RAID Recovery ( -data-recovery-software) in the same way. It seems to me that programs work in a similar way.

As you can see in the screenshot, the program has identified the partitions of my raid array. After scanning it, the files are available.

I suggest first powering down the NAS and removing disk 1 (leaving slot 1 empty). Then power up, and see if you have access to your data. If you do, copy it off right away. Don't revoot the NAS, don't try to reinsert the disk.

RAID isn't enough to keep your data safe, and it is quite possible that you are dealing with a failure of both disks. Hopefully you can get your data back - if you do, then I recommend that you put a backup plan in place for your NAS.

You say you tested the power supply? If you did so without a load on it, that's not a very good test. A failing power supply can possible deliver 5V with no load, but the voltage drops too low once a load is applied.

In the world of data recovery there are virtually hundreds of software developers vying for your money to buy their offering. A few though have really set themselves apart with more functions than the rest. R-Studio from r-tools technology (not sure if that's supposed to be capitalized or not) is one that has really distinguished itself.

In this review I'm going to explain why....

if your going to buy just one data recovery program, R-Studio is your absolute best option.

While there may be some software that seems easier to use, there are none with anywhere close the capabilities of R-Studio that are as user friendly. For the most part the software has incorporated every feature you need into a single window, with a tabbed interface for viewing the various filesystems and scan results you are working on.
