CSPPC: UW SCSI HD does not appear in Early Startup Menu (SOLVED)

I got me this UW SCSI HD (8.4 GB) and would like to install it. strangely it won't show up in Ear5ly Startup Menue.

It DOES show up in HDToolBox (i can install and partition it, it even shows up in Mounter and i can mount it.
But nothing comes up on WB and i cannot format it, because there is nothing to format?

Suggestions very welcome

Term - CSPPC - HD (No Term) - Adapter to 50 pin - CD (Term)

It worked before like this (but i haven't had a UWSCSI HD on the chain yet.)
Do i need to buy me another active Terminator for the second end of the chain?

I'm out of ideas here, what drives me mad is that the drive IS accessable, maybe it's just a plain stupid mistake i'm still doing here?

Help, please

TIA

edit: Funny, as programs like SCSIBench that directly access cybppc.device can actually work with the device, but it refuses to show up on WB!?

edit2: Seems i am not allowed to install the SFS FS directly onto the HD, at least, if i install the disk with FFS and use Mounter i can access the partitions ... well, going forward...
edit2a: Well, you ARE allowed to install it directly, alas one shouldn't change the descriptor of the FS (was the to say CFS/00, i changed it to SFS/00 and boooooom)

@Raziel

So, i had to explicitely tell the CSPPC what i have installed
in the CSPPC early bootup menu. What was able to stay at AUTO
with every single SCSI-2 device i installed before is not with
this crazy UWSCSI HD ... lets wait and see how the ordered
UWSCSI CD performs

Anyway, i have it working now, thanks to the great community
for the suggestions and help

YAY UWSCSI speed...
