Disklabs Data Recovery and Computer Forensics Services recommend the use of a UPS, (Uninteruptable Power Supply), or a Surge Protector, as this is the only known protection for dealing with this problem.
People working on PC’s without power surge protection will need to be aware that lightning can strike at any time any where. It’s only a matter of time before power surges caused by lightning, unstable power supplies and many home appliances can bring down your Computer systems Hard Drive (HDD) which means that you will require data recovery services from Disklabs Data Recovery and Computer Forensics Services. Approximately, 15% of all the jobs recovered at Disklabs Data Recovery and Computer Services are recovered from hard drives with ‘power spike’ problems.
In many cases it’s the external components of the HDD that receive the bulk of the damage as the electricity surge burns out PCB card and the heads inside the hard disk that has failed.
Often internal damage also occurs, mainly burning out the read/write heads and surrounding controller making any recovery of data impossible in this current state.
The W/R heads will need to be replaced in a sterile environment. To achieve this we need to open up the drive lid and remove the heads from their parked position and skilfully replace these with an exact matching pair. The drive should now be in a stable enough position to be worked on with our software based programs. For any successful recovery our software will need to work with data held on the platters within the HDD. This data may at first seem corrupt and will need manipulating in order to get any readable files or documents from the platters.
In rare circumstances, removal of the card is possible with security screwdrivers and a replacement PCB with matching firmware and controller specifications can be used as a substitute. This will enable the data recovery engineers be able to read the raw data from the hard disk platters and then rebuild the corrupted data into something understandable.
