Hard Drive Evaluation

Customer service is one of the most important aspects of working with a hard drive recovery service, because it is likely the biggest factor on which you'll base your purchasing decision. Secure Data Recovery scored an impressive 95% score in our Customer Service Consistency test.

For this test, we asked each of the services we evaluated a series of questions anonymously by email and phone looking for straightforward, consistent answers. We spoke with different representatives through different channels, on different days and at different times. Not only were the answers consistent from one customer service representative to another, but almost all our questions were answered every time. This shows a great deal of attention to detail. Its representatives didn't shy away from questions by providing an off-topic sales pitch instead.

The evaluation process is free and takes one to two business days, which is average. Following the evaluation, the service provides you with a full-scale diagnostic of your hard drive with the cost and estimated date of return. The estimate is a contract. Once you approve the recovery, the price won't increase unless you request additional services. The website even includes detailed instructions on how to ship your hard drive properly so you don't subject it to additional damage.

Recovery Service

One of the best aspects of Secure Data Recovery is its certified ISO 4 Class 10 cleanroom, where standard recoveries are performed. It is currently the only hard drive data recovery service with this type of third-party certification. A few other services claim to have an ISO 4 Class 10 cleanroom, which has 10 times fewer particles per square meter than the standard ISO 5 Class 100 labs but lack the third-party certification to prove it. While having a cleanroom certified using a more stringent standard doesn't necessarily equate to more successful data recoveries, it certainly minimizes one of the variables that interferes with recoveries – and that matters.

Secure Data offers a No Data, No Cost guarantee. You only pay for the data that was successfully recovered. For instance, if the company quotes you a price for $1,000 but only recovers half of the files, then the price is prorated. Most clients have recovered files returned on a new hard drive, but online delivery through secure FTP is an option. However, it's limited to 5GB of recovered data for security reasons.

Secure Data Recovery offers DIY software for handling logical data loss. If your data loss is logical, meaning there's nothing physically wrong with the drive, then your best option is data recovery software, which costs much less and means you don't have to send your hard drive off to a lab. It offers remote recovery, which entails technicians accessing your computer through an internet connection and performing the recovery.


Secure Data Recovery is the only hard drive recovery service we reviewed with a SSAE 16 SOC 1 (Type II) security audit as well as a SOC 2 (Type I) audit. While the SOC 1 certification is certainly appropriate for detailing data privacy protocols with concern to financial records, the SOC 2 Type I is a more comprehensive audit of data privacy and security protocols. Many services don't have an SOC report.

This hard drive recovery service always encrypts data using 256-bit AES encryption and a password that works only once. In addition, the company has security measures in place throughout its facility. Every device (hard drives, RAID, solid state) is tracked from beginning to end. Every area of the facility is locked with password keypads, and each employee has his or her own password, which means employee access is tracked and restricted at all times. The premises are under 24/7 surveillance. No employee is allowed to leave with any media whatsoever. Your sensitive files are safe with this service.

Help & Support

Every data recovery case is assigned a dedicated case manager who updates you on the progress and acts as your direct contact with the service, answering any questions and concerns you have. This manager is your main support system throughout the process. The online portal is one of the best we saw, with a complete history log of the case, results and support contacts. You can also see recovered files from the portal.

The company's website also provides a wealth of educational resources – a blog, articles, proof of certifications and a comprehensive FAQs page. The service gives you all the educational resources you need and makes sure you have access to information concerning the data recovery industry and process, allowing you to make an informed decision.


Secure Data Recovery is one of the best data recovery services available. It provides a thorough evaluation of your hard drive and offers excellent customer service. It's also the only service with an ISO 4-certified cleanroom. The security is comprehensive, and the data security protocols come with a SSAE 16 SOC 1 (Type II) and SOC 2 (Type I) certification.
