The Archive - General Hard Drive and Data Recovery Archive

The Archive contains lots of information about hard drives and data recovery that we’ve been compiling since 2002. Whilst you’ll find up to date information about current issues and problems throughout the rest of the site, the archive contains pages that we feel are still relevant but don’t really have a place anywhere else.

Miscellaneous

Bowie1979

We had a double-disk failure in a RAID5 array which Data Clinic were able to recover and return all the data to us. The service and communication at each stage of the process was excellent. Scott Fuller, Head of ICT, Diocese of London

Osman Idris

They recovered and fixed what no one else could.....THANK YOU!I tried EE, Samsung and Carphone Warehouse in the same day and all three's employees said my device would most likely be wiped of all the data and be returned to me.
