Western Digital Specialist Data Recovery

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 we extracted the rom code and erased the areas where the unique information was stored. We then looked at the tracks where the SA was stored and using specific variable settings and a small amount of trial and error, we managed to get the ROM rebuilt wrote it to another processor on a working circuit board and recovered every single file on the drive.

This is an example of the lengths that MjM Data Recovery are prepared to go in order to get your data back.

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...

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 co...
