I apparently need to load sd_mod.o to get my parents' camera working. Modprobe can't find it, and neither can I, looking by hand. The kernel-modules package on the install disk doesn't have it, either. (For Slack 9.1 anyway) Where can I get it without having to recompile the kernel?

I think sd_mod is the module that handles scsi disks
and other block devices. If you have the bare.i kernel, then sd_mod
is compiled directly into the kernel rather than being a separate kernel
module.

(I'm not using Linux at the moment, so I'm not 100% sure).

Thank you for your reply.

If sd_mod is in the kernel, what else could be causing it to keep coming up as "not a valid block device" when I try to mount it?

Did you look at the output of dmesg to see which device to mount?
If so, then let's just wait until one of the experts sees this thread.

Regards.

I did, and I can't find a device name referred to anywhere. I think it's supposed to be /dev/sda1 or something similar (that's what most of the things I've managed to find in Google said), but I tried "for file in /dev/sd*; do mount $file /camera; done" and everything was "not a valid block device".

Thanks for your suggestions.

Here's some stuff from logfiles that might help pinpoint it:

oot, if you do search at this site for the phrase "digital camera"
you'll find some posts with questions similar to yours. I don't know
if any of them will help you. In some of the posts, mounting the thing
as vfat was the crucial point. Please look through them if none else
answers your question. Sorry I can't be of help. I don't have any
experience with digital cameras.
