I dropped my external hard drive.
I gave it to the data recovery center to recover the disk with important data. As a result of the analysis, they gave information that the chip containing the disc information on the motherboard is not original. They say they need the key code on this chip to recover my data. How can I reach this code. Is there any solution in this regard? Since the data on the disk is very valuable, it is very important to me for your help and feedback. Thank you very much for your help in advance.
