This will be my final posting on the HD stuff, since I'm at my depth.  The
HD gurus may now take over.

Basically, I added some printf's (printk's) to the driver to say what messages
it was receiving and what status returns it was getting from the HD.  The
results were:

Read always works.

Write functions for ca. 10 blocks, then the controller returns status = 255.
Then the driver receives a message from -1 of type 2 with parameters all 0.
After which it steadfastly refuses to function, doing 3 retries, getting a -1
message as above, then returning an error.  (Bug report:  mkfs doesn't check
for error returns from writes.)
