Unclear about unwriteprotecting

[elf at buici.com]

I've built the mtd driver into a 2.2.17 kernel using the mtd-20000704
version.  I am accessing a DOC 2000 (24MB) that was created using the
M-Systems's doc driver.  It has two partitions, one formatted for
ext2.

The NFTL driver sees the partitions find and I can mount them.
However, I cannot write.  Nothing in the code or on the list has
enlightened me.  What am I missing?
