Another option for you:
Go to aminet and download "Fat95" which (IMHO) is far superior to CrossDOS because it allows you to keep all your long Amiga Filenames (none of those PC 8.3 restrictions!)
Also it works on any amiga Workbench from 1.3 right through to 3.9!
Just follow the link below to download it from Aminet:

Hope this helps
