Use the -r option to do the repair manually like you tried Code: sudo gainroot umount /dev/mmcblk0p1 fsck -r /dev/mmcblk0p1 But make sure the umount command really unmounts the device. Did you notice that you got an error during the first try... May be try rebooting to get the state of the MyDocs partition reset to some sane state. Then try the fsck process again.
sudo gainroot umount /dev/mmcblk0p1 fsck -r /dev/mmcblk0p1
