Useing a doc2000 device (32Mb) and a kernel v2.4.14.

After insert some MTD modules :
mtdcore docecc doc2000 mtdchar mtdblock and nftl;
I run nflt_format to format my doc2000 chip;
but it complain :Erasesize not 8Kb - I'm confused!

For someone's advice I skip the erasesize check in nftl_format.c.
so nftl_format works well.
but when I run fdisk on /dev/nftla.
it's say :
You will not be able to write partition table.
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF
disklabel Building a new DOS disklabel.Changes will remain in memory only,until
you decide to write them.After that, of course,the previous content won't be
recoverable.

Command (m for help):

Even if I created a partition and enter "w",the partition also can not be writed
into /dev/nftla.

run nftldump on /dev/mtd0:
