Unable to fdisk DOC2000

I'm using a stock 2.4.4 kernel with the MTD driver
compiled into the kernel. I've managed to get the driver to
recognize the DOC so that it says:
M-Systems DiskOnChip driver. (C) 1999 Machine Vision Holdings, Inc.
DiskOnChip 2000 found at address 0xCE000
Flash chip found: Manufacturer ID: 98, Chip ID: 73 (Toshiba TH58V128DC)
1 flash chips found. Total DiskOnChip size: 16 Mb
The FTL driver, however gives:
ftl_cs: FTL header not found.
The NFTL driver then says:
M-Systems NAND Flash Translation Layer driver. (C) 1999 MVHI
$Id: nftl.c,v 1.57 2000/12/01 17:51:54 dwmw2 Exp $
Could not find valid boot record
Could not mount NFTL device
According to a post I saw earlier, this means the DOC is "hosed"
and needs to be formatted. When I run nftl_format I get:
Erase size not 8 Kb - I'm confused
I removed the check for the erase size as someone else suggested
and nftl_format appeared to work okay going through Phase 1, 2a,
2b, and 3 with no errors.
However, when I try to fdisk /dev/nftla I get:
Unable to open /dev/nftla
When I cat /proc/mtd I get:
mtd0: 01000000 "DiskOnChip 2000"
which looks different than I expected.
Does anybody have any idea why fdisk won't work?
