  • 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 used some software for data recovery on MAC, but THIS IS only one, that help me!!!

I want to upgrade it to the technician tool.
This tool is amazing. I was able to recover 5 years` worth of lost photos by imaging 4 disks from a corrupted RAID 10 array.

It did a byte copy of the disks and then replicated the array layout and I could see the files instantly. I`d recommend it to anyone, especially at these license fees. You`ll struggle to get better for the price.
After several attempts, using various softwaretools, I wasn`t able to recover any files from my encrypted drive.
I almost had to come to terms with the darkest of dark scenarios, losing it all to oblivion and no one to blame but myself.
Then I came across the demo version of R-studio and decided to giving it a final try.
YES-yes-yes... Utterly wonderfully fabulously FANTASTIC R-Studio!
The most important files were in good condition so (the paid version of) R-Studio could recover these right away.
Unfortunately ...
I accidentally deleted several gigs worth of data from an external drive - no restore point. I tried other recovery software, but what was `recovered` was mostly junk files in randomized order. Considering the cost of professional data recovery, and given the online reviews, I decided to purchase R-Studio.

Wow. Everything - like, EVERYTHING I had ever moved to the Trash from that drive - was recovered, folder and subfolder structure intact.

I am grateful and beyond impressed at this program`s price point ...
