I have A4000 Rev D with old IDE drive as primary and DVD-burner with as slave both connected to the one and only IDE port with the same rounded IDE cable. System is OS3.9 (not sure if Boing Packs are installed because this system was installed by another person from whom I bought it).
Now I try to temporarily remove DVD-burner to install another harddrive as slave and to format it.
The second harddrive is properly installed and jumpered, HDToolbox finds it properly and I managed to partition it too, but when I reboot and want to find its icon on Workbench main screen. It will never show up, but instead EMERGENCY_CD icon will appear even though DVD-burner is not connected.
Do I need to do a software dismount for DVD-drive or something so I could replace DVD with another hardrive even temporarily?
I'm sorry if this issue is already asked about in the forums, but it was pretty much impossible to do a proper search about this.
Also as I am one of those people who sold their Amigas somewhere in 1995 and bought them again somewhere 2005. I have forgot many things about Amiga software. So if there is any tutorial available for using HDtoolbox and formatting your second harddrive I would appreciate a link. Thanks! 
You will need to remove the emergency_CD icon from sys:devs/dosdrivers and move it to sys:storage
I would think the OS 3.1 manual would have info on using HDToolbox...
