Known Issues & Case Studies
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.
Current Known Issues (Spring / Summer 2016)
- Data loss problems on Samsung EVO SSD hard drives
- Western Digital Drives with USB interfaces on the hard drive’s motherboard
- Problems noticed with Seagate STxxxxDM001 series hard drives
- Issues with current Z7K500 series Hitachi/HGST hard drives
- Picture loss when upgrading Mac iPhoto and Photo Libraries.

RAID and NAS Data Recovery Case Studies (Spring / Summer 2016)
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

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.
