  • Linear Imaging vs Runtime Imaging vs Multi-Pass Imaging

R-Studio Technician supports three types of object images:

  • Linear imaging: The drive is read from beginning to end by large blocks of disk sectors. When even one sector in the block appears bad, the entire block is treated as bad and either discarded or read sector-by-sector with significant loss of speed. The entire disk is imaged as a result.
  • Runtime imaging: R-Studio Technician writes data obtained from the source object to the target object in parallel to other actions, including the opening of partitions, disk scanning, etc. All further access to the read data is performed from the target object. Only the necessary disk areas are imaged as a result.
  • Multi-pass imaging: The data is read in several phases while trying to process good sectors first and saving the slow or bad sectors for later. The maximum amount of good data is imaged as a result.

The following Table presents the advantages and disadvantages of these imaging types and our recommendations.

Linear Runtime Multi-pass
Advantages Fast for healthy drives Very fast: it images only those drive areas that are necessary to recover files.
You may start file recovery immediately in parallel with disk imaging.
All problem areas are processed and all accessible data is extracted.
Drawbacks Slow for faulty drives. May get stuck on large bad block areas. Images are incomplete. Slow. It's necessary to wait for the imaging process to complete to proceed with further data recovery.
Recommendations Use it for healthy drives or drives with a very small number of bad sectors. Use it for fast recovery. Use it for faulty drives.

I really love your R-Studio product, I am doing Data Recovery as a professional, I used RS since the early versions and I loved the product, as far as I can tell, R-Studio, especially the Tech Version (but including the standard) is one of the best and excellent tools for a pro to have in the arsenal of tools in a pro DR lab, especially combining with the specialized Data Recovery hardware providers like DeepSpar, and PC3000, the rest of `wannabees` out there are waste of time, strongly recommend
I lost more than 200K files from my NAS due to a mistake. I tried 3 different recovery solutions over the 4 TB raid disks, and all of them performed ok but to be honest none of them were able to Raw recover the files and rename them with meaningful names out of the Metadata like R-TT did, then I was able to sort again my files and pictures and kind of restore all of them.

R-TT may not be the easiest or most user-friendly solution, but the algorithm used for the renaming saved me THOUSAND of hours of opening ...
Just recovered my old ext4 partition with R-Studio after trying testdisk and R-Linux without success. That partition was overwritten by another ext4 partition and I was losing my hope until I tried R-Studio demo. It detected all my files and directories again!

Bought it and 100% recommend it for anyone with a similar issue.
Genuinely tried every free program available without luck of recovering a deleted file from months ago. Thinking my file was deleted forever and lose all hope I came across this website as a recommendation.

I was reluctant as it seemed pricey compared to other programs, but damn worth every penny. It managed to even find files I thought were wiped from existence.

Kudos to r-tools, thank you!
Why make incremental backups, when there is R-Studio?

I`m an IT professional who has worked from home for over a decade. Early on in my career, I configured an HP ProLiant Server (Raid 1+0) as a workstation that I would remote into from my laptop. As technology evolved, I began to use it only for email and as a config file repository.

A short while ago, one of the drives degraded, but the HP ProLiant Server (Raid 1+0) still functioned fine on the remaining drive. I was complacent and didn`t replace the ...
