It would be much useful if we could uploading head topography image for each WD family

Just create the topic, add some to get started and let me know. I'll then convert the topic to be a sticky and you can add over time, others can post theirs and we just keep editing the initial post to create a comprehensive list with pictures.

Maybe is not a MRT bug, SPT of 1100 could be make sense if exist helios drives with SPT of 1108
