Fujitsu Hard Disks

The Fujitsu MPG series of drives suffer from a firmware problem that was fist diagnosed in 2001. Fujitsu traced the problem to the chemical constituents in a compound used for the manufacture of the MCU processor on the controller card. Prior to the discovery of the problem, the drives were getting excellent reviews and were fast, reliable and quiet. Once the problems surfaced, we became aware of the issue when we started to receive many hard disks for data recovery - all showing similar symptoms.

The problem affected thousands of hard disks in the field and resulted with firmware problems, mainly in the defect mapping, SMART logs and some other firmware modules and logs.

MjM Data Recovery Limited were one of only a few companies in the world that managed to repair the drives so that nadz could be used.
