Seagate 3TB GoFlex Failure

“I write travel reviews and been storing my travel photos, video logs and assorted documents to my Seagate GoFlex external drive for the last three years. While I have some of them elsewhere, I thought I’d lost a lot of irreplaceable memories when it failed appear on my computer. Seagate suggested their software which saw the drive but couldn’t recover anything. Many thanks to DiskEng for recovering my files. I’ve learned a hard lesson from this incident.”

Bryan Caldercott, Oxford

A Seagate 3TB GoFlex external hard drive enclosure arrived at our laboratory facilities from Oxford. An inspection of the enclosure revealed it to contain a Seagate ST3000DM001 3TB hard disk, the very first drive released using three platters each with a 1TB capacity. Unfortunately, they have proved to be subject to unreliability problems apparently due to the high density of the recording media. The drive electronics was inspected and no physical damage was apparent with the internal disk components.

A sector-by-sector image of the hard drive was secured by our hardware data recovery specialists. Approximately 50 unreadable bad sectors were encountered during the imaging process, the most important of those being unreadable, sector zero which contains the partition information required for mounting the data volume.

A scan of the hard disk image was done by our data recovery specialists which revealed a single 3TB NTFS data volume. This volume was analysed by our data recovery engineers who discovered it to contain approximately 1.9TB of photos, video files and many office documents. A scan was done to determine if any files had been damage by the unreadable bad sectors, which found that a couple of video files and some unnecessary temporary files had been affected. Fortunately, it was confirmed that the two video files were ones which the client still had on their camera and the temporary files are not required.
