I'm pretty sure this problem exists in Linux, specifically in the USB subsystem. Here's why: I have 2 different cards, 1 the original Nikon 8Mb card (although I see that the brand on the back is SanDisk). The other is a Simple Technologies 64mb card. Both show the same problems. Last night I took the 8mb card and did a dd to copy the card to my hard drive (it was a clean card with 1 photo taken by the camera--no problems with the data). I then took the dd image and pushed it back to the card. At this point the picture appeared corrupted when I looked at it on the camera. So it can't be the Linux filesystem. Win32 has no problem with the cards. Formatting the card in Linux made no difference. Dan > > The solution was to sync;sync before umount.
