The DiskOnChip uses NAND flash, which has 'out of band' data areas. A
simple dd won't read or write them. Neither would it be sensible to use the
nanddump and nandwrite utilities for doing so, although they can - you want
to reformat each device individually, with its own bad block map, not the
bad block map of your master.
nftl_format, mkfs and tar or dump/restore are sensible.
What are you partitioning it for, btw?
