Hi Guys
Recently ordered a 2GB SanDisk SD ExtremeIII card from Amazon for my Canon G7. Card arrived and I popped it into camera and took a few shots to experiment.
Stuck card into my card reader and plugged into PC USB. Auotoplay did not fire up so I was a bit suspicious. Navigated to card reader in "Computer" and tried to access pics. Received Windows message that card required formatting before it could be accessed.
Was a bit puzzled as I had read somewhere that all SanDisk cards come pre-formatted.
Did not proceed with PC formatting but replaced card in camera and selected the "in camera" format option. This done I took a few more pics and again tried to view them on the PC. Got the same problem - disk coming up as unformatted. This time selected the option to format in PC but got an error message saying Windows could not complete the format???
Just for assurance I got an older basic SanDisk card - formatted that in camera and took a few pics. Popped it into card reader and Hey Presto off it went as normal and the pics were accessed without problem.

Do I have a duff 2GB card or is something else wrong? Is there an issue with my card reader? It is a Hama USB 2.0 "8 in 1" reader which I have used successfully for several years. Is it up to the job of handling these 2GB Extreme cards? It has worked OK on smaller capacity cards (up to 1GB) made by both SanDisk and Kingston.

Any comments and help would be appreciated.
