that's something really strange, how can you ''use'' os3.0 but you ''have'' os3.1 both wb and roms? i'm trying hard to understand to help but can't see the light this way...
He probably means that he runs Workbench 3.1 on Kickstart 3.0.
@Thomas: as you can see it's ''dificult to cure''
It's not difficult. It's just a matter of afford and/or investment.
Obviously the current combination of this Amiga, this HDD, this ROM version and this Workbench version does not work. You can try the same procedure over and over again, it won't work unless you replace any of the above.
I have mentioned the only possible "cheap" solutions above:
1. If the partitions don't appear on the desktop, they can still be recognised by AmigaDOS and can be formatted from the shell. After that they will appear on the Workbench.
2. If they are not recognised by AmigaDOS, you can try the cut of the reset line.
From here on, it becomes expensive, you have to replace one of the components.
A new Amiga might help, but I doubt it unless it is a different revision and (more important) a different ROM version.
A new HDD (one which has been tested on Amiga before) *will* help.
A new ROM might help, but there is a good chance that it won't (at least if the cut-the-reset-line operation does not help either).
A new Workbench will most likely not help. (There is no newer than 3.1 if you don't even get your HDD set up).
Finally there is always an 80% chance that the problem is sitting in front of the keyboard. :-D
