OK, that may be a problem. The fast filesystem is specified in the mountlist, and if you format the drive for the old file system, then it probably won't be recognized as a valid disk. Also, I believe the old filesystem has a limit of 50 MB, so that's another issue.
Which version of AmigaOS are you running? It sounds like it's a version earlier than 1.3 since the format command doesn't recognize the ffs and quick options. If this is the case then you will probably want to move to 1.3. With older versions of AmigaOS you will be limited to the first 50 MB of your nice big SD card.
If you run into trouble, then you can try this mountlist instead. It will give you a 40 MB partition that uses the old filesystem.
