Hi, my disk broke, until it happened I didn't even know that there was such a thing as SSHD. I called a company that could repair it and then they told me how much it cost, I started looking. Fortunately, I have some experience with programming and electronics. According to what I read on the forums, the terminal output indicates a damaged NAND. I bought a second PCB with the same S/N on eBay. I read the contents of the patient's and donor's EEPROMs and using F3 Rom explorer moved CAP RAP and SAP from the patient's EEPROM and later also IAP. Of course I have no idea what I'm doing :) It didn't help, the disk spins up, but the terminal says FAIL servo op=0100 Resp=0007 and other things. Can anyone please help me? Thank you.

Full terminal log when turned on?
"says FAIL servo op=0100 Resp=0007" - this applies to the heads, not to the PCB.

Either drive is not spinning or heads are bad.

Do you have terminal access after PCB swap?
