You need to have a disk partition layout, a partition slice layout, and a slice file system layout in common between the machines. This is unlikely unless you are running BSD on your Alpha, and even then, that's unlikely, since the layout for BSD on an Alpha would probably be identical to the OSF/1 layout to allow for cross-mounting of file systems between OSF/1 and BSD locally. Local cross-mounting is much more important conceptually than foreign mounting. Probably what is needed is an ISO 9660 writable FS, or some other FS that has the byte order problems and layout problems addressed automatically. The main use here would be ISO 9660 CDROM mastering and removable media. > I know it is possible because I've done it, but I cannot do it again. > Problems are with disk labels.

The easiest thing would be to write a tar, cpio, or backup image to the raw device, and use it as a glorified tape drive instead of trying to use it as a mountable file system in both locations.
