I have a few ST8000NM0055-1RM112 which according to https://www.seagate.com/www-content/pro ... 1510us.pdf are in 512e format, however there exists a sibling ST8000NM0045 which is in 4kn format.

I would like to switch my drives to 4kn format, and I found https://www.synoforum.com/resources/upg ... y-nas.182/ for switching, but that doesn't seem to apply to these disks, as only 512e is available.

I found https://files.hddguru.com/index.php?act ... y=Firmware updates/Seagate& which appears to be the firmware corresponding to the ST8000NM0045 drive with 4kn format.

Before I go do something potentially dumb, is it simply a matter of flashing the ST8000NM0045 firmware to these ST8000NM0055 drives to get them into 4kn format?

I know I could just purchase new 4kn drives, but I'd prefer to use what I already have.

If that is the case, that I cannot flash the 4kn firmware to this 512e drive, is there another way to force the drive to use 4k mode to match its physical sector size?

I wanted to personally validate that claim, and it is true that the software does not want to allow cross-model firmware flashing:
