Are all 3s drive identical?

I got a 1213s and crossflash it to 1653s (CS09)

CS09 reads/burns disc pretty good. But few months later, I found that the drive gives bad KProbe scan and strange noise.

The 1st picture is the same disc burned by CS09 at 8x, scan with TS0D
The 2nd picture is a disc scanned by CSTJ (Incomplete scan)

**CS09, BS0S also gives bad scan

My comment is 1213s may not be identical to 16xxs :confused:

make an eeprom reset:

also new firmware maybe will help:

I have tried them already :slight_smile:

I have tried EEPROM Reset and new firmware

Anyway, I returned my drive for RMA
