A word of caution ...
Slightly off topic I know -- but be warned about SmartMedia cards. I have had a couple of cases in the not-so-distant past in which I have gleefully downloaded a whole lot of files to a SmartMedia card (students' tests) -- only to find that they didn't have the files on them when I got back to base and tried to upload them to my PC.
Irritating and highly embarrassing.
I now have a card reader that writes to both SmartMedia and also to Compact Flash cards -- and now copy everything to both cards. Needless to say, since I have started doing this, I have never had a failure on either type of card.
Have never had any problem with CF cards - and am routinely using a 256Mb card. I wonder whether the exposed contacts on the SM cards don't make it easier to zap the contents with static.
Anyway - for what it's worth ...
