If you think that spinning magnetic media aka hard drives or disks to me and you are dead and SSD or solid state drives are taking over, think again.
The Western Digital Wd600HLHX hard drive is absolutely amazing.
Here are some the specs of this drive;
10,000RPM, 32MB cache, SATA 6G/bs, 1.4 million mtbf mean time between failure, 5 year warranty, read seek times 3.6 ms and write seek time 4.2 (avg), a truly stunning piece of kit for any gamer or performance system, pair these up or better still configure into a RAID 5 configuration you have a decent data protection and file server setup with very fast read and write access times.
Cooling of the drives is catered for by a inbuilt heat sink and offers rack mount back plane for extra colling of the hard drive.
Capacity is now doubled from the 300gb previous model and offers a decent storage size for users that require more room for their digital archive of music, photo’s and the like.
How many hard drives come with a 5 year warranty these days? Not many, in fact it wasn’t all that long ago many manufactures supplied 3 and 5 year warranty, however there appeared to be a shift back to 12 month warranty not so many years back, so this hard drive shows confidence and reliability from the manufacture in the long term performance of this drive, they represent a very good ROI for your data, after all how would you recover if your hard drive failed and you did not have any backup at all? Perhaps data recovery has been attempted and failed, you are left with nothing, no data.

WD Western Digital hard drives and disks can exhibit the following symptoms such as spin and click, or make strange noises, register as an incorrect size, or a family name, not the correct size and serial number as it should be it functioning correctly.
Usually these issues are related to the firmware zone also called the SA and is a very complex area for any data recovery technician requiring years of hands on experience dealing with failures.
The firmware located at the SA (System Area) is a reserved area of the hard drive locked away from any normal user access, and for good reason, it would be very easy to cause major issues with the HDD if the SA as available to all computer users.
Special techno vendor specific commands are used to gain access to this area and are drafted by the manufacturer and T13.0rg which has governance over ATA and similar technology, let me explain a little further what the SA handles.
Each hard drive made is unique! to many who hear this are not totally convinced it is true, after all surely this would impede manufacture times? Not so, the process of covering the platters with magnetic based substance is called sputtering, this process is different from drive to drive, also when the hard drive is receiving its factor formatting procedure the HDD has its own defect lists for itself only, and can not been transferred to another, the defect lists also work with the translator which handles (P)CHS to LBA or lately LLBA, this is the process of converting the physical to logical geometry of the HDD, and it does so with amazing repeatable accuracy, time and again, however due to magnetic failure issues, growing bad sectors, back EMF or similar issues this can become damages, this is where an engineer is required.
So now you have a basic understanding as to why your WD hard drive may have failed and that user repair or intervention simply will not work.
Our engineers are experts with WD Western Digital hard drives and often recover HDD which are declared unrecoverable elsewhere, in fact much of the work received is from existing
