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.

My HP PSC 1510 printer/scanner worked fine with xsane.

I'm using Debian as packaged up here: http://www.cyrius.com/debian/kirkwood/sheevaplug/unpack.html -- the pre-installed Ubuntu didn't have any loadable kernel modules which are needed.
