HDTOOLBOX shows extra scsi device

[sonycman]

Hello!
Using A1200 config with 3.1 kickstart, having workbench 3.1 loaded from .adf.
Primary IDE enabled with .hdf image selected.

And hdtoolbox showing extra scsi device (two in total).

Is this normal, or this is a problem on my side?

It seems extra device is the slave IDE controller, which is disabled in the options.
Strangely it is responding somehow and appears as Unknown in the toolbox, but cannot be written to or inquired from.
