Of course... I didn't mean to imply that sda1.image would be a single picture. I.e. using kernel 2.4, dd is able to read the whole 128M without any I/O errors. Then I am able to mount the image via loopback like this: $ mount -t vfat -o ro,loop=/dev/loop0 sda1.image /mnt/camera No errors, all the pictures are there, etc. Using kernel 2.6 dd won't even read the whole device, as you see above from my first message. > > This is the first time I've plugged my dig. camera into a box w/ > > any 2.6 kernel, so I don't know if it's ever worked.

You mentioned something > about filesystem errors -- what errors do you see? Since the dd command fails in 2.6 but not 2.4, I thought that would rule out any problems w/ the filesystem itself. In the meantime, I snagged all the pictures off the card using kernel 2.4 and reformatted it, so I don't have the same filesystem available anymore. If you still think it might help, I'll snap a few pictures and try to recreate the problem... but I get the I/O errors using dd even with a freshly formatted card. Thanks and regards, -- Mark M.
