See this is an area I found a little odd, with Amigas you could read PC disks using a special piece of software, I had it and it was called 'disk master 2' I think, it was a cover disk on Amiga format or something and if I recall you could basically move txt files and that from amiga disks to PC formatted disks, which then meant you could write documents on your amiga and then take them to a PC to be read. I think it wasnt limited to just txt files, might have also been able to use sound files and that too.
So anyway I was thinking also wasnt Amiga Unix based like Linux? So I thought it would have been easier to get the 2 to mate compared to a PC!
With the whole USB disc drive think I am not sure (yet) how it could actually make a difference that its usb, I know with amiga disks in the PC it just reads it as a non formated disk, mainly because of the file type difference, which is why I was thinking with a USB version it would still read it, but it wouldnt make sense of the data that was coming through?
Also I found a Pinout for the 23pin connector as found on amiga diskette drives:
Infact I found thid area on the site:
which covers tons of things connecting Amigas
Then theres also other PC stuff including a normal disk drive pinouts: http://pinoutsguide.com/Storage/26pin_m ... nout.shtml
Some stuff to trawel through I guess but it might be a start!
