I have to swap PCB for this HDD, with PCB G3448A. I know I have to swap Bios Chip, but I don't know if I have to change both chips shown in the picture attached (https://www.hddzone.com/images/PCB-G3448A.jpg) or just one of them. In that case, which one?

If you purchase the PCB from hdd-parts.com, they will transfer the firmware at not extra cost. AIUI, you only need to transfer IC602.

This is correct. The other one handles the USB bridge.

Be very careful with the temperature to desolder and weld the ROM. If it breaks you will not be able to recover the data.

btw, rom on toshiba can be written using simple tools and some knowledge. However, some tosh family caused me headaches, maybe it was MQ01...

What temperature do you recommend, more or less, for this ROM?
