During my MSET9 usage, I ran into a problem where MSET9 wouldn't uninstall, stating that there were no ID1s, and sure enough, there weren't, I thought this was just an isolated issue, however, upon looking at the homebrew Discord other people ran into the same issue, and there was one consistency that I found, and that was that they were all running Linux. Please look into this issue (my SD card also went Read-Only after installing, you may have a permissions based issue in which you are turning the drives read only, causing the fake ID1s to not be possible to write and therefore deleting the ID1.
