For Smartbasic, I used smartbas10b from the swlist. I then took a copy of this disk (by unzipping the sw item) and called it adam.dsk (but you can call it ssdd.dsk if you want). That saved me having to work out how to create and format a disk, and it would be a guess anyway. So firstly I tried >mame adam smartbas10b -flop2 adam.dsk, this starts basic. You can get a directory with the CATALOG command. Commands are case-insensitive. If you specify a drive, D5 is the first drive (flop1), while D6 is the 2nd drive (flop2). So, CATALOG,D6 to get the directory of the 2nd drive. In Basic, I created a 2-line program, made sure it ran, and typed SAVE test,d6 - and the I/O error appeared. But, maybe loading it via the command-line makes it read-only? I don't know. MAME doesn't ask what you want. So, I started with smartbasic only, then used File Manager to mount the 2nd disk. Now you get asked if you'd like read-only or read-write. So I chose read-write obviously. Tried saving the Basic program again, still got I/O error. So I confirmed the issue. Over to you.
