Trying to transfer photos from iMac (G5 OS X 10.4.11) to an SD 2G card, so that I can mount them onto a digital picture frame for a gift (COBY 8.4 inch). First created a folder with all the photos I wanted to transfer. Total picture file is 132M, SD card should hold thousands of photos. Mounted the new SD in a USB reader. Copied & pasted photos to the SD card, but after around 80 of the 115 pics copied got a message that there was not enough room on the SD card. Tried breaking the transfer up into smaller packages, but this did not help. Finally went to disk utility and erased everything on the card, noticed that it was formatted for MS-DOS, and I may have unintentionally formatted it to "Mac OS Extended (Journaled)". I do not even know what that means. But, it helped, because it then took all my photos as I originally expected. Great. But, when I ejected the card and mounted it to the frame, the frame did not recognize anything on the card or that there was even a card there. I tried to start over with erasing the card, but now the card says there is 16.4MB on it, but I see no files. That's not a problem, for capacity, but I think I have a formatting issue and don't know which way to turn. I did not know there was even a potential formatting issue with SD, I thought you could "plug and play" with any hardware. Help!
