Known Issues & Case Studies

Data Clinic staff work on recovering the data from a severely damaged hard drive using a Spinstand in the clean room.

As the UK’s largest data recovery company we see lots of broken hard drives, servers and mobile phones that come in for recovery each week. Because we see so many faulty data storage devices, we are often aware of apparent problems early and in addition to documenting them, can identify ways to get around these problems and recover the data. Historically, Data Clinic were one of the first companies in the world to discover the firmware fault on the Seagate 7200.11 series of hard drives, and the serious Fujitsu MPG firmware fault several years before that.

On this page we’ve highlighted a few of the recent known issues we’ve seen with some current hard drives, as well as some interesting RAID and NAS data recovery case studies.

RAID and NAS Data Recovery Case Studies

Due to it’s complexities, RAID and NAS devices provide some of the most interesting and challenging data recovery work that we do.

Netgear 4 disk NAS

The Archive

As we are adding information to this site all the time we have developed an archive area that contains lots of useful links to articles we’ve written since 2002.

The archive contains both recent and older information on all aspects of hard drives and recovery that we don’t have room for elsewhere on the site.

I contacted Data Clinic to see if they were able to recover data from a external hard drive that had just stopped working. Their was response was helpful, informed, patient and really friendly. The whole process of collection of the faulty drive through to delivery of the retrieved data was second to none - and at a reasonable cost. Highly recommend!

I had an excellent experience with Dataclinic. It was a complex recovery after a hard disk failure and they got all my data back. Very happy to recommend.
