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.

Slow Reponding Toshiba Drives

Toshiba Laptop Data Recovery Some problems have been found with Toshiba Laptop drives where the computer will fail with any of the following symptoms .. The drive hangs during boot Unable to access data Computer is very slow Problem with Drives We found the problem which is related to the G-List ( Grown defect list )it either becomes corrupt or is not readable. If it is not readable by the drive then the correct translator algorithms can not be run and so the drive slows down or even stops completely. Solution to Toshiba Hard Disk Problem. The solution is very complex and requires specialist equipment to enable rebuilding of the defect maps externally to the drive. However, once this is achieved the data can be accessed and a near perfect recovery is possible. For more information on this problem please visit our Toshiba Data Recovery pages.

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...
