Heh, good point! I tried the following:

# dd if=/tmp/image of=/dev/mtd/2
32+0 records in
32+0 records out

# dd if=/dev/mtd/2 of=/tmp/copy count=32 bs=512
32+0 records in
32+0 records out

# ls -l /tmp
-rw-r--r--    1 root     root       16384 Jan  1 00:00 image
-rw-r--r--    1 root     root       16384 Jan  1 00:01 copy

# diff /tmp/image /tmp/copy
Binary files /tmp/image and /tmp/copy differ

I.e. not the same, no... You know why?
