Chris, You scared me for a while. I have a credit-card-sized multi-format card reader (USB), and when I tried it just now, the Compact Flash from my Canon PowerShot S30 would not mount. I tried over and over again, and, FINALLY it mounted. I am also in 10.2.4, but using a G4 Quicksilver tower. Maybe if you try a few more times to mount it before giving up? --Steve At 10:51 AM -0800 2/27/03, Chris Johnson wrote: >I just purchased a 512 MB compact flash card for my Nikon 950 >Digital camera.
