我boot linux后，想把我的rootfs通过sd卡导到mtdbloc3里面，操作如下：

# flash_eraseall /dev/mtd3
Erasing 128 Kibyte @ 7b60000 -- 24 % complete.
Skipping bad block at 0x07b80000
Erasing 128 Kibyte @ 1ae80000 -- 86 % complete.
Skipping bad block at 0x1aea0000
Erasing 128 Kibyte @ 1efe0000 -- 99 % complete.
# mount -t yaffs2 /dev/mtdblock3 /mnt
yaffs: dev is 32505859 name is "mtdblock3"
yaffs: Attempting MTD mount on 31.3, "mtdblock3"
block 989 is bad
block 3446 is bad
# df -h
Filesystem             Size    Used Available Use% Mounted on
/dev/root                9.5M    5.2M    3.8M  58% /
tmpfs                   55.8M       0    55.8M 0% /tmp
/dev/root                9.5M    5.2M    3.8M  58% /dev/.static/dev
none                   10.0M    2.5M    7.5M  25% /dev
tmpfs                   55.8M       0    55.8M 0% /dev/shm
none                   55.8M    12.0k    55.8M 0% /var/run
none                   55.8M       0    55.8M 0% /tmp
/dev/mtdblock3       496.0M 494.4M    1.6M 100% /mnt

为什么mtdblock3 100%被使用？明明刚格式化阿，这样我无法导入我自己的rootfs文件系统
