I have read about an Amiga file system for Linux (hoping that it was ported to MacOS X, but no..not yet) I have been able to back up most of my old files from my Amiga IDE drives on Windows XP by setting it up under WinUAE. (I have one very old 2.5in 80meg drive I used in my CD32+SX-1 that couldn't be found but that was using it through a 2.5in external housing through the USB. I think I just need a normal internal adaptor.) Otherwise everything worked like a charm with the 3.5in drives inside the system.
