Data Recovery of 19TB from a RAID 6 Array Failure

Data recovery became critical for a small business in Queen Creek, Utah, when their Linux-based storage system suffered a major failure. The system, a RAID 6 array built with Seagate drives, hosted nearly 19 terabytes of essential business data on a virtual server.

The problem began with input/output errors targeting the /u02 partition. Running the diagnostic command xfs_repair -n revealed serious issues, including B-tree corruption, inode problems, and CRC errors—clear warning signs of file system damage. Although no drives had failed outright and a hot standby was available, two disks showed predictive failure. The IT team replaced the drives one at a time and allowed the RAID controller to rebuild.

Unfortunately, the rebuild didn’t solve the issue. The system still couldn’t mount the file system. A full repair using xfs_repair completed, but the result was discouraging: all recoverable files ended up in the lost+found directory, disorganized and unusable.

That’s when the business turned to WeRecoverData, the leading data recovery company trusted for solving complex RAID and file system failures.

The WeRecoverData team carefully analyzed the RAID 6 array, understanding how delicate the situation was with partial file system corruption. Using advanced recovery tools and their deep experience, the engineers reconstructed the directory structure and recovered the scattered files. Within a short time, the full 19 TB of business data was restored, organized, and delivered back to the customer.

Thanks to WeRecoverData, the small business avoided a devastating loss. Their operations resumed with minimal downtime, and what once seemed like an impossible situation ended in a complete and successful recovery.
