“Thanks for the work in returning my files. Our Linux server started running slowly, and files before we could copy all the web site files, source code and office documents. Thoroughly recommended.”
Stephen Faulkner, Stratford-upon-Avon
From Stratford-upon-Avon we received a 4TB Seagate hard disk drive at our laboratory in Oxford. When the hard drive was inspected by our hardware data recovery engineers it revealed no electronic problems. It was however, soon apparent that a problem with read/write heads was causing issues accessing data sectors. The drive inspection found that one of the heads had failed, causing alignment problems when attempting to read sectors from the drive.
Using a donor read/write head stack our hardware data recovery specialists were able rebuilt the drive to overcome the problem. This enabled them to secure a sector-by-sector image copy of the drive, which was a time consuming process due to same areas of the drive being slow to access. Approximately 500 unreadable bad sectors were encountered during the imaging process, where were all found to be clustered in a small area on one single platter surface.
When our data recovery specialists examined the image of the disk revealing four partitions pertaining to a Red Hat Linux installation, consisting of a small boot partition, a root partition, swap area plus a home partition of 3TB in capacity. The 3TB XFS home partition was considered the most important, containing all the user data and shared drive space. The partition contained approximately 2.1TB of web page files, source code files and many office documents. The bad sectors encountered during the imaging process were found to be all contained with the swap area, thereby having no affect on the user files.
