I hope I can get this fixed.
While hoping to try the Cacko ROM, I tried to reformat my SanDisk 256MB SD card and now I have a $70 postage stamp. Since I tried to format it to EXT2, no device I have can reformat it back to anything usable.  I\'ve tried my Mac, PC, Zaurus, camera, a Palm M Series, all with no luck.  My Z won\'t mount it or recognize it (even in the terminal).  The PC doesn\'t see it at all, and my Mac sees it but won\'t format it.  
Any suggestions?
