Failed Controller Takes HP ProLiant RAID 5 Offline

Failed Controller Takes HP ProLiant RAID 5 Offline

New York-based Consolidated Technologies, a managed IT service provider that helps businesses manage and protect their computer networks, recently experienced difficulties with its company server, an HP ProLiant ML350 G6 tower with four Seagate enterprise level 500 GB hard drives configured as a RAID 5 and running Windows OS.

The company used the HP server as a domain controller and file/print server for the storage of critical client documents and QuickBooks accounting files. When the RAID controller failed, Consolidated Technologies could no longer access the server. Hoping to avoid permanent data loss, the company contacted Secure Data Recovery Services to see if we could help.

Diagnosing Data Loss

The first step our expert technicians take is to conduct a thorough diagnostic to determine the scope of work. After receiving the Seagate drives in our data recovery center, we found that they had read and reallocation errors from bad disk sectors.

Two of the four drives also had stuck read/write heads and required invasive repairs. In addition to the physical drive damage, the RAID configuration had also been lost. Our developers would have to rebuild the configuration by hand.

Custom Solution

Once we received authorization from Consolidated Technologies, our technicians replaced the read/write heads and successfully imaged each Seagate drive in a certified Class 10 ISO 4 cleanroom. The cloned content was then sent to our development team.

Next, our developers stitched the Microsoft Server RAID together and manually extracted all customer data using proprietary utilities modified specifically for this case. Once all customer data was recovered, it was securely extracted to our secure storage servers.

Successful Outcome

Secure Data Recovery engineers were able to fully restore all of Consolidated Technologies’ lost data: 656,323 files in 113,218 folders, for a total of 449 GB, including critical office documents and accounting databases.
