This particular model Western Digital WD5000AAJS hard drive has been known to our labs with various types of failures.
WD Western Digital hard drives and disks are a large manufacture and their storage products are used from system buiders such as Dell to custom PC makers from across the globe.
Overheating or power surges have been observed in the WD5000AAJS range of hard drives, this will severely damage the PCB and must be shutdown, please do not try to restart the HDD as it will cause further damage to the drive.
Following a power surge the heads may also become damaged this will be made evident by a clicking or ticking noise, again if your WD hard drive is making this noise please switch off straight away.
If the heads have failed in the Western Digital WD5000AAJS then our in-house clean room and microsurgery engineers can rebuild and repair the drive, this process would require good heads in replcement of the failed heads, this process is complex and should not be attempted at home or in a DIY type approach as it could damage the drive further and yield your hard drive unrecoverable.
Our lab has special hardware that can access the hard drive at a very low level, beyond what any user can achieve, our system can 'talk' directly with the special area of the hard drive to understand or diagnose what may be the problem, from this diagnosis we can engineer a solution.
Other areas of WD5000AAJS are firmware failures, this can be seen as the HDD not being detected at BIOS level to reporting the wrong geometry size, our labs are equipped to handle this type of failure.
If you have dropped or knocked your Western Digital WD5000AAJS hard drive you may have damaged the heads and the parking zone, this area parks the heads when the drive is off and if the drive has been dropped it may have damaged the head stack, in this state if the disk is repowered then damage to the disk surface will occur and cause further damage to the surface.
Our labs and engineers are available for hard drive data recovery services to help you gain access to your important data.
