I read the following, " an SSD cannot be securely erased. When Disk Utility tries to write data over the entire drive, the SSD’s firmware will write that data where it chooses, and that may mean that some portions of the SSD remain unerased, and thus may contain recoverable data. If you have sensitive information on an SSD, you should probably replace the SSD with a new one before selling, or simply not sell the computer." Question, if this is true and I have a password protected folder, could the folder be recoverable and still read without a password? Thank you.
