Data Recovery for Failed a RAID Array

Failed and Offline RAID Recovery

ADR Data Recovery specializes in recovering data from failed RAID controllers, inaccessible RAID volumes, offline RAID containers and damaged RAID arrays. If you have had multiple hard drives fail in a RAID array or experienced a failed rebuild attempt, our RAID data recovery engineers are equipped with the latest technologies--including our own unique, proprietary methods--to restore your data.

Recovering RAID from SQL servers, Exchange servers, and large RAID arrays that have failed, gone offline or are inaccessible requires extensive training and sophisticated equipment to rebuild the RAID volume and restore good, usable data. DO NOT ATTEMPT to rebuild your RAID array if multiple hard drives have failed or are offline. It will destroy your data! We have been in the RAID data recovery business for over 10 years and successfully recover critical data from RAID servers for businesses, colleges, healthcare organizations, and government entities across the United States, every day.

ADR Data Recovery Recovery has a regional labs and service centers across the US, where your server drives and storage devices can be serviced. Choose the RAID recovery center nearest you. Emergency RAID data recovery services are also available or we can schedule a courier to pick-up your hard drives at your location.

Common RAID Failures

Some factors that could cause a RAID array to become inaccessible could include: damage to the RAID stripe or parity, due to one or more failed hard drives, a power failure, a back-up that may have been restored unsuccessfully, malicious human intervention, failed system updates or OS upgrades, viruses, or a boot drive failure.

We have successfully recovered data from all Dell, HP, IBM, Compaq, Gateway Servers and operating systems, including relational database servers, web servers (Apache and Microsoft IIS), business application servers, document management systems, and content management systems.

RAID data recovery proceduresinvolve determining the damage, source of the problem, and how much data can be extracted. For serious failures, this may involve careful dis-assembly and extensive manual repair of hard drives in our clean room in order to rebuild your array and restore your data. Our RAID data recovery engineers are experienced with all RAID versions and operating systems so you can rest assured we will do everything possible to get back on track as quickly as possible.

Common Problems

  • The RAID controller has been corrupted.
  • The array is broken due to a single bad drive.
  • Power failure or surges have caused damage.
  • An array rebuild has failed.

“ADR Data Recovery worked tirelessly to stitch the data back together [on our client’s RAID 5 array]. I was amazed when ADR Data Recovery claimed that 100% of the data had been recovered. I was even more amazed when I saw for myself that they actually had. I hope you never have to go through a data disaster like this one. But if you do, it is my strongest possible advice to ONLY trust your data to ADR Data Recovery.”

“Our RAID failed on a Friday just before we all were about to go home and enjoy our weekend. We contacted ADR Data Recovery Data Recovery and set-up an emergency recovery with them. They sent one of their technicians to our worksite and he took the hard drives back to their main lab in Folsom. Later that evening, I was contacted by their tech and was told an e-mail containing the recoveryable files was in my inbox. To my relief, they were able to do a full data recovery and Monday morning we were back in business. Truely amazing!”
