5.25" Disks to Use in Apple IIgs and copy .dsk image files to Apple

["Joel Ostroski" <jostroski@socal.rr.com>]

Hello I have two questions.

1) I have Sony 5.25" Double Sided High Density Diskettes.  Will they work in
a iigs 5.25" floppy drive?  Reason I ask is that I ran copya to copy a dos
3.3 disk and is copied but it would not boot.  I booted off the original
floppy dos 3.3 disk and catalog'ed the copy and the files were there.  I
also get errors on the disks.

2) I have a bunch of .DSK images of apple ii software, I have used apple
disk transfer gs and have made a null modem cable.  I can transfer the
program dump file that needed to be sent to the iigs to run for file
transfer but anything that I write to disks (the type of disks outlined in
question #1) they do not boot.  The images to work in my emulator though.
When I made a ProDOS disk it stated UNABLE TO LOAD PRODOS

I have this iigs but only 1 disk and that is the DOS 3.3 disk.  NOTHING
ELSE.  I would sure like to use my disk images to make workable floppies to
run on my iigs.

Your help is appreciated!
