How ATA Registers Work After some requests from users we have started restoring some of the technical pages we had on our website. There were a few on our old website that are being converted from the old site tro the new one. The latest one is the page that describes how the ATA registers work on a hard disk drive. With explanations of the purpose of their functions and has been updated to include 48 bit LBA addressing., The page can be found at : https://www.mjm.co.uk/articles/how-hard-disk-ata-registers-work.html We are also in the process of building some technical videos showing exactly what goes on when accessing hard disks.

Another busy weekend updating the information on our RAID pages. Added some new pages and text. Recovering data from raid arrays is a complex problem that requires complex software, we started developing our own raid recovery software back in the early 2000's We are now a market leader for raid data recovery and can recover from the most complex of raid systems, including EMC Isilon SAN and EqualLogic systems. Full details of our raid recovery service is available at our website .. Raid Recovery For more information about us please follow the link to our main site here: Data Recovery Services

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 s...

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 thi...

Apple have released an update that is reported to corrupt data. Our experience is that folder names are lost, and in a few cases the whole filenames are lost. Please contact us for data recovery from the Maverick Upgrade Failure Data Recovery : Maverick Upgrade Initial reports indicate that it is only affecting Western Digital drives and WD are looking into problems with the Maverick Update and the Western Digital drivers for OSX. More information can be found on ZDNet http://www.zdnet.com/western-digital-warns-customers-os-x-mavericks-may-destroy-drive-data-7000022800/ Please phone us for data recovery on 0800 072 3282

Wer'e now in the process of rebuilding our old website. www.mjm.co.uk After a lot of thought we have decided to rebuild our old domain .. We first bought this domain in 1994 for our old company 'MjM Computer Publishing' At some point I will write a history of our company, The site became synonymous with data recovery and helped us to market our business. A three letter domain is very easy to remember and served us well in the early years. Then came Negative SEO. Our original site was well rankedi n Google's 'SERP' results for years we were no1, 2 or 3 for our major search terms. We suddenly saw this drop, and drop. We checked what was happening and found links from pages where we had not requested them, asking to get links removed was futile as they never even responded. So we set about buying other related domain names and developing sites which would initially rank well, then fall off again. More recently, Google has updated its ranking algorithms so...
