Yes. The standard number should be 1, but my system has three drives,
so I accidently send out the wrong version.

Can you use both disks under tos?? Are your device numbers right.
Also there is a fix out on patch 3. Have you tried that?
I think you will need it, but I'm not 100% sure any more.

See the comment in stwini.c

No. 3 is fine. 
drive 1 = scsi 0 lun 0
drive 2 = scsi 0 lun 1
drive 3 = scsi 1 lun 0
etc.
You are/you should have one drive configured as scsi 0 lun 0
and the other one as scsi 1 lun 0 (if they have their own controllers,
if you have two disks on one controller then they are lun 0 and lun 1).

It should work. However, I do not have any removable media to test 
this on. Your comments are appreciated.

No problem.
