X-Copy

[Ilwrath]

I believe "AmigaDOS" copy is what it means, or basically a standard Diskcopy like the Workbench does.

Exactly.  DOSCOPY and DOSCOPY+ are AmigaDOS copy modes.  It's like the Workbench diskcopy, except the version in X-Copy is fast and reliable.  Won't work for non-AmigaDOS stuff, or copy protected disks.  

NIBBLE copy will copy some copy protections and non-AmigaDOS disks.  Of course, if you can't read the original disk from workbench to begin with, you won't be able to read the copy, either.  ;-)

X-Copy TNG will do it if you mount PC0 and PC1.

Not much help for his AmigaOS 1.2....

Heck, I don't even think X-Copy TNG, itself will load under 1.2, let alone the AmigaDOS 2.1+ files for PC0 and PC1.

Dos2Dos or an early CrossDOS is the only way that I know of.

And getting either of those to an Amiga, if you have no way of writing Amiga disks is tough, too.
