I was on the road again and missed this thread the last few days. Yes, I have implemented an "extended attributes file" for Pi1MHz that holds all the mode page details. It will also identify discs correctly and allow for different variable sectors per track. The FileStore doesn't use the fixed 33 sectors per track as in BeebEm. Below is an example for the R0652 drive. The format also allows for other Mode pages to be added.
All the code works and it recognises discs correctly. Writing to the extended attributes file through the page select command isn't quite finished.
The are some limitations with the code from the oddy website. It appears to be based on some very early Pi1MHz firmware (pre-GitHub versions) and is very difficult to integrate with the current release. The filestore utils won't work fully with it as not all the extra SCSI commands have been implemented. It's also hard coded for 33 sectors per track.
The filestore E01 is also running the 1MHz Bus at 2MHz and I found I had to overclock a Pi2Zero for it to communicate, although there were still some dropouts with some commands. Dominic has implemented some changes which should solve this but I haven't been able to test it yet and I'm away from the hardware for the next 2 weeks. I can however check the GitHub repo and make the fork public or invite people when requested.
