RAID Information and Fault Description: Recently, I received a set of 12 disk arrays using enterprise-grade Seagate ES.2 hard drives, model ST3100340NS. The client is a film and television production company that uses the server to store large video files. According to their report, three hard drives failed, which caused the RAID array to crash. No unnecessary attempts were made to fix it themselves. The operating system in use is Windows Server 2008. RAID Detection Process and Failure Analysis: The data recovery engineer from Darth first tested the three faulty hard drives and discovered that all of them had physical bad sectors. This indicated serious hardware issues that could potentially prevent data retrieval if not handled carefully. RAID Data Recovery Process and Results: To begin with, sector-level disk-to-disk mirroring was performed on each of the three failed drives to ensure no further damage occurred during the process. After that, the underlying data structure of the disks was analyzed. Since the data mainly consisted of video files, there wasn’t much text-based information available for reference, making the analysis more challenging. By searching through different parts of the disk and repeatedly verifying the results, the engineers were able to understand the unique RAID6 configuration used. They also encountered an HP internal and external double-cycle technology, which added another layer of complexity. Unlike the conventional left-side structure with 16 strips, this setup used a right-side structure with 32 strips, creating a special double-loop RAID configuration. In response to these unique structures, the Darth engineers modified their existing software tools to match the actual characteristics of the RAID setup. After performing data reorganization and extraction, they successfully recovered 6.73TB of data, achieving a 100% complete recovery. Challenges in This Case: A major challenge during the recovery process was the limited amount of $MFT (Master File Table) records found on the disk. Although some MFT entries were identified, they were not sufficient to fully reconstruct the file system, which made the task more difficult and time-consuming. Advice to Customers: If you encounter a RAID failure, it's strongly advised not to attempt any DIY fixes, especially if the data is critical. Professional data recovery services are essential to minimize the risk of further data loss. Once the data is recovered, you can proceed with RAID repair to restore the system as efficiently as possible. Always prioritize professional assistance when dealing with complex storage systems and important data.
