About Data Recovery

I thought I would write a blog post describing what data recovery is all about. To put the phrase in to a description it would be 'Recovering data from damaged computer storage media'

The problem is that the description would not cover reasons. So there are are few main reasons for data loss in the first place. These are (and this list is not exhaustive) ..

  • Logical failure - deleted files, formatted disks, virus damage, random encryption events, overwritten data. MjM Data Recovery Limited have written their own software for accessing logical problems on most operating systems offering a better chance of recovery.
  •  Firmware problems - this is where something has gone wrong with the built-in systems on the hard disk or ssd drive resulting with the storage system not working as expected. Either the device is not usable at all, or if it is it is very slow, sporadic data access or corrupted data. MjM use the latest firmware tools and for some systems have developed their own.
  • Bad Media Problem  this is where the media on the hard disk has failed or is in the process of failing. It usually manifests itself by taking a longer than usual time to load files or start up. The problem can eventually end up with  the entire media becoming inaccessible. Using advanced imaging software it is possible to recover the vast majority, and often all of the data on drives with this problem
  • Hard disk head problems  this is a problem that whilst seems daunting and very worrying is on where the data can more often be recovered than not. Modern hard disk heads are very small and are susceptible to damage from knocks and jolts. But MjM Data Recovery can replace the damaged heads with ones from a working drive in order to recover the data. It is something that is done several times a day in our labs with good results.

It is very important to analyse the cause for a given problem, often we can get enough information from a phone call with the customer to find out the state of the media, then once recieved it goes through a thorough diagnosis using the lates technology. Once the problem is identified precisely only then do we make any attempt at recovery.

ReFS (Resiliant File System) Data Recovery

MS ReFS (Resiliant File System) Data Recovery Microsoft introduced their Resilient File System (ReFS) with Windows Server 2012. It is a 'self repairing' file system that detects errors and rebuilds data. MjM Data Recovery are now able to recover data from this file system from single drive servers  to multi drive raid systems . Please visit our main website for details of our Data Recovery Services .

Laptop Data Recovery

A large number of computers sold are laptop computers. They are light and portable. Modern laptops contain very large hard disks at the time of writing this article 500Gb are often seen here for data recovery. One of the most common problems we see are drives where the heads have crashed. The main cause is actually part of the design of the computer - remember the bit where I said 'they are light and portable'? It is easy to put the computer on your lap, then when you need to get up, lift the computer up and put it to one side. This movement can cause a head crash especially if the heads are reading or writing at the time. Most manuals that we have seen recommend putting the computer on a firm surface like a desk or a table and in fact NOT putting it on your lap - strange that they are called 'laptops' when it is not recommended to use them as such. Some manufacturers have developed hardware that detects when the computer is being moved and pulls the heads to a saf...

Raid Recovery

Raid recovery is a specialist type of data recovery service. RAID is an acronym of R edundant A rray of I nexpensive D rives and consists of at least two drives that are configured as a single volume or container. The most common forms of RAID are described below. RAID 0 requires a minimum of two drives that gives the full disk size of both drives as a single volume the data is stored in stripes each stripe consisting of a block of data on each drive block sizes are typically 64kb but we have block sizes from 4kb to 2 Mb in size. This is the cheapest type of RAID but has no redundancy. If one drive fails, then access to all data on both drives is lost. RAID 1 Requires 2 drives the second drive is an identical copy of the first drive meaning that you only get the equivalent of one drive for the price of two. Expensive but offers redundancy so one drive can fail and you can still access the data on the second drive. RAID 5 Requires a minimum of three drives. Is similar to RAID 0 in...
