I used mine with CrossDOS to read PC CDROMs, pull jpegs off them, etc.
I don't think that CrossDOS will read CDs.
I read on Wikipedia that it was designed to be compatible with the ISO 9660 CD-ROM discs but do not know if these refer to the normal CDs we buy from computer shops or some old standard.
ISO 9660 is a way how to arrange files inside the available storage. It has nothing to do how the CD was manufactured and whether it is a CD-ROM, CD-R or CD-RW.
There are two levels of ISO 9660:
level 1 = all file names upper case, each file name consits of eight characters + one dot + three characters extension (like MS-DOS).
level 2 = all file names upper case, max. 32 characters, max. one dot.
and there are extensions:
Rockridge = upper + lower case characters, Unix protection bits.
Amiga = upper + lower case characters, file notes, Amiga-style protection bits.
Windows also knows another extension which is called Joliet. It allows upper + lower case characters with up to 256 characters per file name (I think).
There are only few Amiga CD file systems which can read Joliet: AsimCDFS, CacheCDFS and AllegroCDFS.
Additionally to the file system used, the quality of the CD matters, too, because the A570 is rather old with a rather imprecise laser. Manufactured CDs (silver) work best. CD-Rs might work better when written at low speeds (1x or 2x). CD-RWs might not work at all.
