Mounting AFFS R/W?

[Alan <alanrb@bigfoot.com>]

Hi,

I've got my machine working a little better, though the disk is still
showing errors. In any case, I'm trying to R/W mount an AFFS formated
removable drive under Debian so I can put the install files on it, but
it refuses to mount.  I have other HD partitions for AmigaDOS that I can
mount just fine. Both R/W and R/O, but since I have heard of potential
issues with R/W, I don't want to try it on these partitions. They are
all formated in the same way with the DOS\1 format. The mount for the
removable, even R/O, always fails with this message:

mount -t affs -o ro /dev/sdc /mnt
AFFS: Can't find a valid root block on device 08:20
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
	or too many file systems

Any ideas what this means and how to fix it?
