In order to use HDToolbox on a hardfile, you need to set Surfaces, Sectors and Reserved to 0, i.e. 0,0,0,512 instead of 32,1,2,512. The "RDB info" is created by HDToolbox when you use "change drive type".
In order to use FFS with a hardfile, you need to specify the path to the FastFileSystem file, i.e.
hardfile2=rw,:/home/user/Amiga-Stuff/Hard-Drive/WB_1.3,32,1,2,512,0,/home/user/Amiga-Stuff/ROMs/FastFileSystem,uae
To format this HDF you should use the format command in a CLI shell and specify the FFS and QUICK command line options. After format you might need to reboot in order for the file system to be recognised (at least this happened to me in WinUAE).
