Hi all: I just went through a similar fire drill with my TiPBG4-800 using 10.2.4, my Canon EluraMC2 with MMC cards, and a Dazzle 4-in-1 PC Card adapter. My PB couldn't read photos from the MMC card that had been formatted in the camera. I had to reformat the MMC card FAT16 in my Windows 2000 notebook, then validate that the card could be read in my PB and in the camera. Then I took photos and brought them into iPhoto with no further problems. Same process worked for an SD card. Regards, Jim
