as quite a newbie I studied a lot in order to solve this master/slave problem my Toshiba T9100 has with the latest NEC slimline drive ND-7550A. Unfortunately you don't have your Reverse ATA tool, which seems to avoid soldering, for this drive - but for the 6650 model.
So let me ask you: Is your tool (maybe in parts or by changing the bat-files) also usable for the 7550 drive? I figure I don't need other firmware changes but the reverse setting to avoid the IDE Error and make the drive visible.
Thanks a lot
