It's possible that some firmware versions have a hard coded sector size of 520 and refuse the setting.


What OEM & FW are they?

Try the enterprise version of SeaTools.

The following URLs are old, but you should be able to find something more current:

If using Seagate's Linux tool ...

st -B 520 /dev/ice
