Secure Data Recovery, a famend information restoration specialist, has carried out an unique challenge for TechRadar Pro, uncovering a startling discovery: tens of millions of deleted information have been efficiently recovered from arduous drives bought on-line.
The firm acquired 100 arduous drives at random (excluding solid-state drives and reminiscence playing cards) and applied cheap information restoration methods to evaluate their findings — it’s price noting that they didn’t make investments sources into recovering information from broken or encrypted safe drives, as these circumstances have been deemed salvageable.
Out of the 100 arduous drives acquired, Secure Data Recovery managed to recuperate information from a powerful 69 drives, encompassing 30 broken HDDs and a single encrypted drive. It is noteworthy that not one of the drives have been hybrid fashions that mix solid-state reminiscence with conventional spinning drives.

This enlightening end result sheds gentle on a prevalent challenge: nearly all of customers lack complete plans for securely disposing of or erasing information from outdated or out of date arduous drives (notably these using PATA or SCSI interfaces).
Consequently, a major variety of customers eliminate arduous drives with out correctly eliminating delicate information, whereas others merely delete them with out using sturdy information erasure strategies. Surprisingly, solely a minute fraction of customers (merely 1% within the analysis) take the additional step of encrypting their complete drives to safeguard their information.

The challenge’s outcomes additionally point out that years of warnings issued by eBay, urging sellers to totally wipe laptops and storage units earlier than promoting them, have largely gone unheeded.
Sanitizing a tough drive
A spokesperson from Secure Data Recovery clarified {that a} arduous drive is taken into account “sanitized” if no recoverable information is discovered, implying that it has both been fully wiped or crammed with random patterns, such because the Department of Defense’s three-pass methodology.
Importantly, the spokesperson assured that after the restoration course of, the corporate adopted its rigorous data-handling practices, encompassing greater than 100 safety controls — they emphasised that at no level did they entry the contents of any recovered file, and the info was securely purged after the completion of the challenge.
Jake Reznik, the esteemed Laboratory Operations Manager at Secure Data Recovery, shared his experience on the protected and safe disposal of arduous drives, whether or not they’re inside or exterior; Reznik recommends that customers again up necessary information earlier than initiating the sanitization course of to forestall any potential information loss.
This will be achieved via the usage of backup software program or by choosing a dependable cloud backup service; he advises deciding on an acceptable destruction methodology based mostly on particular person necessities — as an illustration, erasure software program affords a reusable arduous drive by overwriting the unique information with a number of passes of random patterns.
It is crucial to confirm that the chosen program has successfully wiped all information to make sure full erasure.
Irreversible destruction strategies
Alternatively, there are some irreversible destruction strategies that may render arduous drives fully irreparable:
- Degaussing: makes use of a strong magnetic discipline to demagnetize the platters and scramble current information.
- Media shredding: includes operating the arduous drive via a tool that tears its parts into small metallic items.
- Disintegration: generally employed by enterprises, reduces the arduous drive to a effective residue by lowering particle measurement
- Puncturing: puncturing the drive’s platters in a number of spots utilizing a drill.
In common, bodily destruction strategies provide the next degree of safety for arduous drive disposal. Some people go for a mixture of destruction strategies to make sure absolutely the irrecoverability of their information.
