[clug] Mounting an SD card

Hi all,

I just bought a Canon IXUS II digital camera, which seems to be as yet 
unsupported in linux, at least it's not a USB mass storage device. So, 
no dramas, I have a USB SD card reader that does work as a mass storage 
device. When I plug it in, it shows up no worries in /var/log/messages.

Where I'm striking problems is actually mounting the SD card. The reader 
is a 6-in-1 type (CF/Microdrive, SmartMedia, Memory Stick, SD/MMC). I'm 
pretty confident that the SD port is /dev/sda. However, when I tried to 
mount it, I get this message:

[root at gcalaptop root]# mount /dev/sda /mnt/camera
/dev/sda: Input/output error
mount: you must specify the filesystem type

So my question has become, what is the filesystem type? I checked in 
windows, and it seemed to think it was a RAW filesystem. Does that make 
sense to anyone? On another laptop that has a built in SD card reader 
(also running windows xp pro), it simply said the card wasn't formatted.

Any thoughts? Ideas?

Thanks heaps,
