Over the last few months I've had two 2GB PNY SD cards die, the most recently two days ago. This time I used a 4G SanDisk SD and today (!) it completely died. I put it in another linux box and there is no longer any partition table.
I've been running debian/Lenny from Martin Michlmayr's bootstrap (http://www.cyrius.com/journal/debian/kirkwood/sheevaplug
). It sees very light duty -- fetchmail every 15 minutes and some music sharing using gnump3d where the mp3s are on a large powered external USB disk.
Any suggestions or ideas on where to debug? I'm getting tired of buying SD cards.
