Dear lovely people, I apologize for not having time to delete or edit my last post - actually, there are no problems with the file! It turned out that the problem was that I had formatted the flash drive in Windows... 3 of the four files had no problem copying, only part 2 had problems for some reason, but whatever the reason, it was caused by the fact that I had formatted the flash drive in Windows. After I formatted the flash drive in the Mac Os9 system, the problem disappeared.
I have now managed to install on a separate partition Instant Daw, I have some problems with the mouse freezing, but when I turn off the extensions with shift held during boot, the mouse works normally. I will find out which extension is causing the problem and disable it. Tomorrow I hope to have time to test the system with my audio interface, if they work together I will be very happy. I may be the first person to confirm or deny that Digi 002 r works on Mac Os9 system. This will probably be a long process involving a lot of trial and error, I work all evening and almost all night as a sound engineer in a bar Friday and Saturday, and tomorrow I probably won't have time, but these days I hope to find time and try to get the audio interface working.
Thank you all for your time, I'm glad I found this wonderful site.
Postscript: I apologize for my bad English, I'm not a native speaker and I'm using google translate because I'm very bad with grammar.
