Fujitsu Hard Drive Problems

Usually, after a certain period of time HDD’s start behaving erratically, begin to click or stop spinning. These days these devises are virtually extinct, but some data recovery labs still get them in, and in Fujitsu’s case, the data is recovered every time due to their perfect mechanics. However, some years back, Fujitsu brought out a line of faulty MPG drives that made them infamous in the data recovery business. The Cirrus Logic chips were faulty in some five million of these HDD’s, and Fujitsu blamed the supplier. Apparently, the epoxy mould compound that was used in the Numbur chips and Cirrus’ Himalaya 2.0 was supplied by a Cirrus Logic sub-contractor, who made some changes to the product resulting in the short-circuiting of the chips and the subsequent data loss.

This story, unfortunately, left Fujitsu with an unfavourable reputation, and they have never produced 3.5 inch IDE drives again.Today, the only drives to be seen are those used for SCSI interfaces and laptops. Of course, these are hardly ever brought in for data recovery thanks to Fujitsu’s near perfect firmware and mechanics.

Common Symptoms of Failure

The most common mechanical issues seen for 2.5 inch Fujitsu laptops are bad heads (knocking, sweeping, clicking ) and heads that are stuck to the platters making it impossible for the drive to spin up .

These drives need to be opened in a class one hundred, clean room to retrieve the data successfully. I’ve said it before, and I’ll say it again: Don’t try to open the drive on your own! You may scratch the surface and damage the data even further.

Bad Sectors

Another typical problem for Fujitsu drives (especially laptops), are bad sectors. After time the magnetic media that covers the platters starts to decay and the magnetic domains are unable to turn in the correct direction.

When the HDD attempts to read data from the damaged bad sector, it usually freezes, clicks or starts scratching. This then causes more damage to the surface heads and results in further data loss. The moment you experience any of these symptoms when reading important files on your PC, immediately stop the drive and contact your nearest data recovery centre.

Please note: trying to read the data will only result in more problems. the data recovery labs use specific imaging tools (ignoring checksum check) to read the raw sector data. This is normally the only successful way of retrieving the most data from these LBA’s.
