Disposing of old Gadgets? Safeguard your Personal & Confidential Data first

A new Stellar data recovery study reveals hard disk drives available on classifieds websites contain high-risk data

We are all saddled with an inventory of old hard disk drives coupled with an urge to quickly get rid of same by selling them off on popular online sites. We believe that by formatting our Drives, we have taken requisite precaution for securing data privacy. But is this sufficient? A recent analysis done by Stellar Data Recovery reveals that hard disk drives available on second-hand marketplace sites contain a significant amount of confidential data. For the sample collected, sensitive data was uncovered in 100% of cases.

As part of the study, multiple hard disk drives were purchased from India’s leading online platform which facilitates buying and selling of second-hand products. The data from these drives was then recovered using simple Do It Yourself software Recovery Tools available online. For all such cases where the data was not securely erased, the data recovery was accomplished easily within a day.

Most consumers in India are unaware that data can be recovered from their legacy drives and mobiles and steps like formatting are not enough for ensuring data privacy. Consequently, there is a grave risk of private and confidential data from these legacy devices being passed onto the buyer of such devices. The study further reveals that the vast majority of Indians are still unfamiliar with data sanitization methods; often referred to as data erasure methods, data wipe methods, wipe algorithms, and data wipe standards. The drives purchased for this study were formatted but not wiped using any correct method and after running ‘data recovery software,’ huge data contained in files were recovered. This underlines the need to adopt secure data erasure methods before disposing of old & obsolete hard disk drives, refer

Worse, imagine your credit card details being available along with your identity documents, these two coupled together can lead to your entire credit limit being wiped off immediately with funds withdrawn with explicit and malafide intent.

Consequently, over 80 countries and independent territories, including nearly every country in Europe and many in Latin America and the Caribbean, Asia, and Africa, have now adopted comprehensive data protection laws that prohibit the disclosure or misuse of information about private individuals.

In such cases, the company stands to lose not only its business but also credibility in the market.
