Hello,
I recently bought a Canon Powershot A95, I also got a Sandisk CF 1 gig memory card and formatted it. I shot a movie about 20 seconds long, and waited for the green light to stop flashing. 4 minutes later it was still going!

Ok so then I did the no no and tried to shut off camera, no good; tried pushing every button on camera, nothing worked. Ultimatly ended up opening battery compartment!

haha took care of that problem. I figure since there was nothing on the card no biggie should i lose it right? Well, then i tried to take pics and get this Memory card error, ok no biggie I'll just try to reformat. When I try to it kind of freezes up my camera, black screen, like it powers down but doesn't draw in the lens or cover. I put in a smaller 64 Mb card works great, no problems. What does this mean? Do i need to buy a new card? Any suggestions on which one?
Thanks for any advice/opinions.
