MJM Data Recovery

We have recently made a major update to our NAS Recovery pages on our website at www.mjm.co.uk/nas-data-recovery/nas-recovery.html We have included pages for Buffalo Linkstation and TeraStation Drobo Systems Netgear ReadyNAS Recovery Netgear SC101 and SC101T Recovery Qnap NAS Data Recovery Synology NAS Recovery Thecus Data Recovery Western Digital NAS Recovery  Quite a few pages added with information about NAS Recover from all above. Next is major update for RAID pages to include several new Server pages.

Western Digital ROM Recovery A recent job received was a Western Digital 2 TB drive. It had been to another data recovery company before we saw it and they were unable to recover. We examined the drive and found that the processor on the controller card (circuit board)  had failed. Another problem was that the ROM ( this device contains information about the drive and is unique to every drive ) was embedded in the processor meaning that another technique (aka Hot Swap) has to be applied in an attempt to read the system area on the drive. This gave us access to the system area where we could access the modules used to create a ROM. So far so good. We then hit another problem, all of the ROM modules were completely empty so it was impossible to rebuild the ROM using standard techniques, this we believe is the reason the other company could not recover. This did not stop us though, at this stage our senior engineer was given the job and taking the drive we used for the hot swap

Fake Memory Cards. After seeing countless fake memory cards received for data recovery, we decided to write some software to help users determine if they have a fake memory or genuine memory card. The problem with the fakes is that they are so good, they actually appear to have the advertised storage space and it even seems that the full amount of data can be written. The only problem, is that the data overwrites some of the existing data rendering the older data useless. Our experiments indicate that (at least with the devices we tested) that the files and folder structures seem to be OK as they list as expected. The problem comes when the memory reaches its true physical limit. At that time, the data starts overwriting at the end of the card. As the file system information is updated, as normal there is no way of knowing, until you open a file that has been overwritten. It has gone, and unfortunately is most likely not recoverable.  Of course there will be exceptions to this ru
