internal floppy drive works fine under GEOS65, but not in 'normal' mode

Hm, kein Plan, bei mir geht das eigentlich - aber ich hab auch ehrlich gesagt keine "alten" Disketten verwendet sondern direkt mal formatiert & dann benutzt.

Hab grad mal ein paar überkommene 3"5 eingelegt, die bringen Fehler "66,Illegal Track or Sector,110,05", oder, auch populär, "27,Read Error,40,00" aber Dein Fehler 73 ist nicht dabei.

Geos65 hängt recht lange an den "Fehler 27", bei Fehler 66 schmeißt es dann den "disk error $02"

Not reproducable here, Mega65 formatted disks are working as expected, differently formatted disks throw errors as expected, but not error 73

Maybe a dumb question but : do you do a MOUNT (without additional parameters) in Basic to tell the system you want to access the internal drive ?

Bei CBM-Laufwerken ist 73 keine Fehler sondern die Einschaltmeldung ....

Jetzt wo Du das so gekonnt sagst hab ich mich an mein schlaues Buch vom Datenbäcker erinnert, da sind ja tatsächlich ganze Seiten mit den Nummern drin...

Yes Sir, It has been mounted.

BTW: There are no silly questions, but maybe weired answers.

What kind of disks are you using (DD / HD) ? If HD -> got the second hole covered ?

Maybe try to write back any D81 Image (with BACKUP) instead of formatting

If that won't work, I'm out of ideas ...

There are some known timing inaccuracies in the IEC serial routines in the MEGA65 KERNAL that noticeably interfere with some external drives and printers, and this may explain the behavior you're seeing. These are getting fixed over the next couple of releases.

It's possible that GEOS is using its own low-level IEC driver that happens to work better. (I don't actually know for sure.) You might see better results in GO64 mode as well.

yes, Geos use ownn disk drivers.

Phura : No idea , but do you have a RAM expansin in your setup? As far I remember Geos can only work correctly with 2 drives (same type). If you have a RAM expansion and 3 or 4 drives, on drive must be a RAM...

ah sorry, no not with the internal drive. I missed that bit. I'm not able to reproduce these issues with the internal drive.
