R-Studio Technician supports three types of object images:
The following Table presents the advantages and disadvantages of these imaging types and our recommendations.
Linear | Runtime | Multi-pass | |
Advantages | Fast for healthy drives. Drives can be scanned during their imaging. |
Very fast: it images only those drive areas that are necessary to recover required files. You may start file recovery immediately in parallel with disk imaging. |
Fast for healthy drives. Drives can be scanned during their imaging. All problem areas are processed and all accessible data is extracted for faulty drives. |
Drawbacks | Slow for faulty drives. May get stuck on large bad block areas. | Images are incomplete. | Slow for faulty drives. It's necessary to wait for the imaging process to complete to proceed with further data recovery. |
Recommendations | Use it only for knowingly healthy drives. | Use it for fast recovery. | The best choice for all drives. If the drive is healthy, multi-pass imaging works like linear imaging. If there are some or many bad sectors on the drive, they will be processed accordingly. |
