I have 32GB card here...
root@amd:/home/pavel/WWW/wear/tinylight# time cat /dev/mmc1 > /dev/null cat: /dev/mmc1: Input/output error 1.32user 49.03system 4184.78 (69m44.789s) elapsed 1.20%CPU
...maybe it was because of powerfail? I'll try to run badblocks to recover it...
...I did. Badblocks did not help, but cat /dev/zero > /dev/mmc1 did.. And yes, thosse 'temporarily bad blocks' seem very much powerfail related.
Its bad, because ext2/3 does not seem to handle this very well... not even fsck does the selective rewrite... :-(.
