Emunand tool? I thought you meant backups from d9 or something. Emunand tool according to several devs is outdated now and might be dangerous to use. I'm not comfortable using that as I don't really want to lose anything.
If d9 still is fine to use for this experiment, then ok, I'll do the backup and restore later tonight, then fill the card up. After filling it up, do I just delete what I filled, copy rxTools to sd again, and try?
Yeah, it's still a matter that has to be within rxtools no matter what the result is. In which case, I suppose div_4 should be the current solution, even if it gains no speed improvements. Until a solution is found that is.
If you formatted your emunand with GATEWAY a long time ago, then emunand tool is safe to use.
D9 uses the same old sdmmc driver with no error checking at all! You may have the same errors there but D9 will just silently skip errors. Lower clock rates is only a measure to lower the probability of underruns to balance between high transfer speed and error handling routine occurance. The PS SD card reader will handle all the errors, as far as it is correctable by SD card controller itself, so the data will be read and written properly until SD card controller or wear-leveling reserved area are failed.
So there is a safe solution:
1. backup with D9
2. backup another one time with emunand tool
3. restore with emunand tool
4. restore with D9, if you prefer
Well, and fill the rest of the card with junk
