I'm offering a 5$ reward for somebody who can teach or give some guides on how can I recover my files in my corrupted internal HDD. I already tried to put it on other CPU, but it seems that it doesn't have any current running on it. I tried to remove the board at the back of it, but sadly I don't have any spares yet. Please, someone, help me recover my files.
Some people already said that internal HDDs aren't repairable, but I don't believe them.
Remember that internal HDD consists of parts: logic board (PBC), headers,.....etc.
Turn on your device and connect the hard drive if it makes a noise. Your problem in heads/platters "will require a lot to fix" else the problem is either in the software or from the PBC unit.
You can try some solutions from YouTube to make sure that the problem is not in the software.
Hardware problems need some knowledge "It is best to ask an expert or nearest maintenance center."
