RAID 5 SAN Rebuild Failed

“Our SAN server failed while attempting a rebuild, leaving us unable to access many important documents and files, which hadn’t been copied to our backup system. Thanks for all the advice and work in recovering our data.”

Paul Reid, Manchester

A SAN RAID system containing five 2TB Western Digital drives arrived from Manchester at our laboratory in Oxford. An examination of the array reveals that all the drives were in working condition. During the imaging process to secure sector-by-sector copies of the data a number of bad sectors were found on drive, which had caused the rebuild failure.

A detailed examination of the images of the drives by our RAID recovery specialists revealed a RAID 5 array architecture, for which they created virtual RAID array. Due to the nature of the redundancy inherent in RAID 5 the data for each bad sector could be recreated. An analysis of the virtual RAID array found it to contain an 8TB NTFS data volume, which contained approximately 3.6TB of data files.
