I suffered (and to some extent still suffering) with similar
troubles and ended up completely "blank" SD card with "dd
if=/dev/random of=/dev/mmcblk0" command, and then repartition it with
fdisk as described in wiki. Also you can try slowing down glamo
rate for SD access by getting some hints from, although the latter
trick has to deal with another problem.
