Fujitsu MHT2020AT (20,0 GB) Data Recovery Information
Fujitsu drives fail and the MHT2020AT (20,0 GB) is no exception to this.
   
I have been using a laptop hard drive in a sabrent 2.5" external enclosure for a few months to move files around from one computer to another. The enclosure came with usb cord which has two usb plugs; one for data, one for power. It sometimes craps out when transfering files. In which case I just unplug, reattach and try again. But yesterday when this happened, I plugged the drive back in, the unit powered up but windows no longer recognises the drive. I get a message "usb device not recognised." I have also tried the drive in a couple computers running windows 2000. I get a similar error on these machines "unknown usb device." The drive worked on these computers before as well.

Fujitsu's reputation has certainly improved since they admitted a few years ago that they had released around 9 million defective drives from their MPG and MPF hard drive series into the market with faulty chips (Cirrus Logic Chip). After several months of use hard drives usually failed to spin up, behave erratically, start clicking etc. This happened many years ago, but we still receive these old Fujitsu Hard Disks into our data recovery lab and in 100% of the cases we get all data back thanks our Fujitsu MPG Data Recovery Solution.
When these drives fail it is essential that you do not attempt to replace a faulty controller board with one from a working drive. Information on the board is specific to the drive it has been attached to and it will not function anywhere else. What's worse is that a different controller board can cause mechanical failure and dramatically increasing the risk of rendering your data unrecoverable. As soon as you suspect your Fujitsu drive may be about to malfunction, turn the drive off and remove it from the system as soon as possible. The sooner you power down the drive the better your chances of recovering lost data once you send the drive into us for diagnosis. These days, hard disk drives from Fujitsu (including 3.5", 2.5" and 1.8" notebook format) generally perform with higher than average reliability than is available from other manufacturers.
The heads on my Fujitsu(MHT2020AT (20,0 GB) model) click but it only lasts for 30 seconds. It does this and then spins down and the clicking stops. The drive is not recognized in Windows XP or Windows Vista.

Fujitsu drive's can spin up and the head starts clicking right from the beginning with a regular clicking sound. More times than not this a sign of bad heads, if this is the case it is very important to perform accurate diagnostics and eliminate a chance of possible firmware corruption or PCB failure that sometimes could also cause clicking.
The last typical Fujitsu hard drive issue applies also to all other hard drive makes and models, the problem is called bad sectors. After some period of time the disk platters were the data is located starts to degrade and bad sectors appear. freezing, scratching and sometimes even clicking. Whenever the drive attempts to read bad sector it could start freezing, scratching, ticking and sometimes loud clicking. This leads to further damage to the surface and causes more data loss. As soon as you start experiencing such symptoms while reading important files stop the drive immediately and consider sending it to a data recovery company like ourselves for a free diagnostic. Any further attempts to read the Fujitsu drive would just add up to the problems and make more data unrecoverable. In our Data Recovery Lab we use expensive imaging tools that are capable of force reading bad sectors from Fujitsu Hard Disks. This is usually the only way to effectively retrieve data from these Drives.If you experience any of the symptoms described above with your Fujitsu MHT2020AT (20,0 GB) please call us on +44 (0) 2890 961976. If you hear your Fujitsu MHT2020AT (20,0 GB) hard drive making some other unusual noises please call us on +44 (0) 2890 961976.
