Hello Guys, i have this drive that spins right and became Ready but can't detect the family in PC3K because its SMR HDD and i have to unlock the ROM. I read the ROM in a external programmer but when i try to unlock SED HDD gives me this message "Wrong ROM header block ID". I think i read well, the size of the file is 512 bytes, but PC3K doenst open it. Does any one know what is the problem? Thank you. Best regards.

I figured it out. The specific voltage to read the ROM file is 1.8 Volts. I now have the full ROM size and information. Going to try to Unlocked.
