This information is provided for use at your own risk and should only be used if the data on your drive is not worth the money to invest in professional repair. If the data means anything to you -- if you need it for your work or for legal purposes -- DO NOT USE THIS METHOD. If your the next step is to throw away or otherwise recycle a really dead hard drive, then proceed at your own risk!
Read this first! If your drive made a clicking sound the first time you plugged it in, any time you plug it in again causes loss of data by damaging the magnetic layer on the drive. Do not attempt this self repair if the data is important to you for work or legal reasons. Some of these techniques are "Hail Mary" attempts that will either work orrender your drive truly, finally, really dead. This will totally and finally kill any part of data that is not already damaged.
Steps To Repair Your Harddrive....
Whatever you do, you will need to repair the hard drive first.
We know now, it is because the System Area cannot be read. You can have 4 main reasons (and a possible combination of them) for this to happen:
- Heads are damaged
- Firmware on the PCB
For heads and preamplificator…well you only have a choice which is to swap the head of your drive. This is where it gets expensive in terms of data recovery services. Head swapping should be done in a clean room ISO 5, but if you are skilled enough you can try it in a clean environment if you don’t plan to spend money anyway on your data. Head issue is very common if you dropped your external hard drive for example.
If the SA is scratched you might have a shot through a live pcb swap. It will basically bypass the reading of the SA and you have a cheap shot at getting your data back.
For firmware issue on your PCB, a PCB swap is the operation you should be looking at. This is doable by most individual thus not that simple,as you need to move components of the old PCB to the new one.
