Replacing a hard drive PCB alone will not erase your data. However, it's important to note that data recovery is a complex process, and any mistakes made during the process can result in permanent data loss.
If you attempt to replace the PCB yourself or use an inexperienced technician, you may accidentally damage the hard drive or cause other issues that can result in data loss. Therefore, it's recommended to seek professional help from a data recovery specialist who has the necessary tools and expertise to perform the replacement process safely and effectively.
It's important to remember that even with professional help, there is no guarantee that all of your data will be recovered. The success of data recovery depends on various factors such as the extent of damage, the type of hard drive, and the age of the hard drive.
