Hard Disk Recovery

Data recovery from hard disk drives is one of the most technically advanced operations performed by computer data recovery engineers. Much of the work involves highly skilled engineers that have engineering knowledge of how a hard disk functions. Not only mechanically, but electronically and logically.

There are many situations where an engineer will examine a hard disk then find it has to be completely disassembled and rebuilt with new parts to replace the worn parts. This involves opening the drive in a clean room environment.

Some drives suffer from Firmware corruption so the engineer will need to know how the individual manufacturer (and in many cases specific model ranges) store the firmware on the drive. In most cases this area is not accessible to the end-user so specialist equipment is needed to access the firmware on hard disks.

Also, a drive may be suffering from an electronics problem which will require specialist techniques as many modern hard disks use unique ROM content on their drives which means that the electronics board can not be replaced and the old one will need to be repaired, or the engineer will need to rebuild a ROM manually to suit the drive.

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...
