Interesting, second camera is reporting errors on two different blocks:
# cat /dev/mtdblock11 > temp11
cat: read error: Input/output error
# cat /dev/mtdblock12 > temp12
# cat /dev/mtdblock13 > temp13
# cat /dev/mtdblock14 > temp14
cat: read error: Input/output error
# cat /dev/mtdblock11 > temp11
cat: read error: Input/output error
# cat /dev/mtdblock12 > temp12
# cat /dev/mtdblock13 > temp13
# cat /dev/mtdblock14 > temp14
cat: read error: Input/output error
