Working with the Third-Party Hardware
The Technician version of R-Studio can work together with third-party hardware developed for in-depth data
recovery. Currently, the following devices are supported:
DeepSpar Disk Imager™
5.1 DeepSpar Disk Imager™
DeepSpar Disk Imager™ (DDI) is an HDD imaging device specifically built for data recovery from hard
drives with hardware issues. It greatly increases imaging speed, accuracy, and integrity of data retrieved from
such drives.
The main features that DDI provides when working with hard drives are the following:
Direct low-level access to a hard drive bypassing the computers BIOS.
Disabling specific drive read/write heads.
Disable SMART subsystem, Bad Sector Reallocation, and Read Look-Ahead
Read sector timeout controlled by Software/Hardware/PHY drive reset commands
Bit level analysis of corrupted data to filter out the read-write channel noise
Fully customizable multi-pass imaging
And many more others an advanced disk imager must have. You may learn more about DDI on its vendor site:
DeepSpar Disk Imager™.
DeepSpar Disk Imager™ basics
The main idea of data recovery with DDI is to clone data from the source hard drive with a certain level of
hardware malfunction to a clone drive and perform data recovery operations either from the clone drive or while
data is being cloned. Such approach greatly reduces tear and wear of the source hard drive and reduces further
deterioration of its state.
There are two modes in which DDI processes disks:
DDI clones the entire source hard drive to the source one consequently, sector by sector. Any further
data recovery will be made from the clone HDD.
DDI clones those sectors of the source HDD which have been read during data recovery. Such readings
are optimized to minimize the movement of the drive's head unit. All following reads from those sectors will
be done from the clone disk. For example, if files are to be recovered from a partition on the drive, DDI
will clone the boot record of the drive, the file table of the partition, and the sectors of the files. If the
partition is scanned, the scanned sectors will be cloned, too. All consecutive operations, such as file
preview, and so on, will be done from the clone disk. This greatly reduces the time necessary to perform
the recovery operations and furthermore hard disk wear.
