Well that sucks, cant view any of your pics in UK, .

Yes you can write stuff back to disk, so real amiga can read it.
However, not sure about Copy protected disks. Doubt something like X-Copy would work for those.
DOS based disks, like workbench, etc etc. will work fine.

Every Standard ADF (880KB) works fine, even NDos Disks since they don't have any copy protection info on them

If you want to do that, just connect the Greaseweazle to a PC and you can write back anything that has been preserved, including copy protected disks ... but that is not possible on the A600GS itself !

You buy a Greaseweazle like this -> https://sordan.ie/product/1530/greaseweazle-v41-usb-floppy-adapter-flux-reader-writer--case/

Put an old PC floppy on it and connect it via USB with your A600GS. Then you set any of the four floppies (DF0 to DF3) as REAL DISK drive in the A600GS menu and maybe even one as virtual floppy drive.

Then you have two options :

1) boot up any AmigaOS (self installed or Amibench) and use any transfer utility like TRANSADF, TSGUI or AMIBLITZER to write any ADF to the REAL DRIVE or
2) use for example X-Copy, insert ADF in virtual Drive, real disk in real drive and do a copy 1:1

Both works fine ...

Yes, use a Greaseweazle
