Well, as long as you have fotos of _how_ to add this hardware into the drive, 
properly...? Or was everything just piggybacked, again :-)

I have read your post saying that you were using "256 bytes of 512 bytes of 
each harddisk sector". Didn't you say this? So this sounded to me like every 
sector of the 1541 was mapped to a sector of the harddisk, wasn't it?
Certainly, you can dump 8192 GCR bytes from the 1541 directly to the harddisk, 
but then how'd you manage the harddisk-sector-allocation? To me, it seemed to 
be "natural" to dump each 1541 sector to each sector of the harddisk.

How are you going to map this to several harddisk sectors, then?

Ruud, I tried to look at your webpage and download some of the stuff in the 
links, but it didn't work for me:\images\1541ide8.png

Seems like you have bad links, I tried to use

and it didn't work. Please fix your links and then I'll look at your code.
