run partprobe and see if that makes a difference. It forces the kernel to re-organize it's idea of what partitions are available. I would have thought SD Cards were treated like regular hotpluggable devices like USB storage, but maybe not. I'd be interested to see the results of running partprobe. -- Alan McKinnon alan.mckin...@gmail.com
