John,
No, the format command is for the entire disk. The base protocol page on your 
website is accurate when it shows that Format, Drive Status, and Drive 
Condition are the three commands that are not bank specific. The rest are by 
adding 0x40h to the command.

I would correct one item though. The TPDD2 isn't two banks of 100k. Rather, it 
is 200k that can be used by either bank. The banks seem to serve two purposes. 
First, it gives you a total of 80 file names instead of the 40 that the TPDD1 
provides. Second, it gives you a way of grouping files. The 200k of space is up 
for grabs. I verified this by putting 135k on Bank 0 and then put some extra 
files on Bank 1. You could use all 200k in one bank if you wanted to.

I've got the program up and running now. The one item I want to add before 
uploading it to the members area, is the ability to duplicate a disk. To do so 
I'll have to delve into the sector access protocol of the TPDD2. I'm familiar 
with the FDC mode of the TPDD1 but the TPDD2 will take some time to sort out. 
I've read through your page on it and that is what I'll be using to start 
coding.

Kurt

I’ve been working on a program that will talk to a TPDD2 directly from a PC. So 
far, I can read, write, delete and format a disk But I can only read, write and 
delete from bank 0. When I try bank 1, I’m getting errors, and the errors I’m 
getting are not listed in the error table on the Bitchin 100 site. I’m stuck. 
Has anyone done work with the second bank? Other than adding 40h to the third 
byte of the commands, I was under the impression that the commands were exactly 
the same.  Kurt

Does bank 2 need to be formatted separately?

I haven't played with real drives all that much.
