DiskSense Forensic Unit

The DiskSense Unit utilizes the fastest and most efficient interface connections available, and is built-to-last using the highest quality components one could source. It includes a built-in oscilloscope for current monitoring (primarily used in diagnostic functions) and write protection switch for source media.

To ensure high quality and efficiency of our tools, we test them on hundreds of storage devices.

DiskSense: under the hood

DiskSense unit inside

DiskSense is basically a very small computer running a Linux OS. However, neither normal computer's BIOS nor basic Linux kernel are suitable for handling of damaged hard drives, simply because neither was designed to handle hard disk failures very well. We have invested a significant amount of research and development efforts which allowed us to build a highly customized and fine-tuned Linux kernel that completely overcomes these issues. Additionally, this kernel features:

DiskSense also features our proprietary circuitry for ultimate hard drive's power control:

These features are a must when dealing with damaged hard drives.

For example, low-level control of the SATA, USB and IDE ports allows Atola Insight Forensic to deal with hard drives that do not properly initialize, have many bad sectors, or freeze frequently due to internal (mechanical) failures.

SATA PHY control allows resetting a frozen hard drive without a power cycle which saves quite a bit of time while imaging, and reduces the chances of further hard disk degradation and failure.

Current sensing allows Atola Insight to diagnose a failed hard drive even if it has electronic or mechanical damage. Please see Disk Diagnostics for more details on how this works.

Overcurrent protection detects when the hard drive draws abnormal current and stops the hard drive to prevent any further damage.

Overvoltage protection circuit ensures that in the unlikely event of the DiskSense unit malfunction, the attached hard drives are not damaged in any way.

DiskSense unit is fully controlled by Atola Insight software via the Gigabit Ethernet interface, hence no Linux experience is required at all in order to operate it.
