transfering *.dsk from mac/ibm to gs

[aida@zip.com.au (Advanced Integration Designs Aust.)]

i was wondering if someone has got this to work
i was looking at ftp.apple.asimov.net and found some old apple 2
*.dsk disc images..how are they supposed to be made back onto 5.25"
disk?
i have adt running on the apple 2gs and on the mac and ibm..
doesnt seem to work..i have terminal programs on both though and i
can transfer *.shk files between them without problems..
any help would be appreciated..
also..is it possible to format a 3.5" disk to dos3.3?
i found a site with a utility amdos and amlauncher or something..
apparantly you can format a 3.5" disk to dos 3.3
and the launcher lets you launch dos 3.3 programs with in gs/os..

anyone heard of this?

thankyou
