what version of AmigaForever are you using? I have 2010 and neither that or a previous version would work, which is why I used ClassicWb and the installed the network options off the OS3.9 CD later.
I used amiga forever 2011 version not sure if much different to yours.
I may try do same again has I sent this one i got working off. When i sold my old amiga 1200 with aca1230 and amiga forever 5.
going try soon just backing up my microdirve whats on allready in fat32 format.
Basically if i recall i converted fat32 to rdb then formatted to ffs to 2 partitions if 4gb or less if more than 4gb i use smart file system.
once done this i then just coped every from workbench fold off workbench 3.x and also everything from work to corresponding work partition on new rdbed disc.
I will test this soon
