This may not be the problem at all, but in most installs, /mnt is where
you put other devices and you can have quite a lengthy list, such as
/mnt/floppy, /mnt/hdc3dos, /mnt/cdrom etc. Each of these points must
have been made with a mkdir command before they are used, as does the
/mnt itself, therefore one should have a '/mnt/amigaffs' mountpoint, and
use syntax like this
mount -t affs -o ro /dev/sdc /mnt/amigaffs
And if the disk is a complete disk, with no partition table installed in
the rdb area of the disk, it may refuse to mount. I have one scsi
device, formatted ext2, that I've not fdisk'd, and although it mounts
and functions in r/w just fine, there is a message in the logs at mount
time about its missing partition table. Other file systems may be even
pickier.
If you have the disk 'partitioned' and the filesystem installed on it by
using either hdtoolbox or rdprepx, then you probably should change the
/dev/sdc to /dev/sdc4 or whatever partition number on the disk you're
mounting. Even if its all one partition, it would be a good idea to use
one of the amiga partitioning tools, and hdtoolbox works for this
although I prefer rdprepx myself, to make a whole disk partition and
install the ffs on it. I don't think linux will use the ffs thats
there, but it probably does need the rest of the partition info stored
in the rdb area, the first 2 or 3 tracks of the disk in order to
properly mount the rest of the disk as a partition from that data.
As another poster commented, you might have to use the
/dev/sdc'address_on_scsi_buss' device since zips are fond of 4, and
can't be set at any lower device number on the scsi bus, ISTR the other
option being address 5.
This, as I said, might be all hogwash, but it makes sense to give it a
try.
Cheers, Gene
