Hi
A couple of other disks that are very useful Amiga Computing Issue 51 Coverdisk34 August 1992 called Arcadia and CUAmiga 100 DOpus 4 and or Amiga Computing June 1992 Issue 49 with SID v2.00. You are trying to trackdown software called MultiDOS. This lets you format DOS disks. Saves you having to do it on a PC.
Most copies of Amiga Computing cover disks from the 1992 era self boot into their own version of Workbench. By following the guides online and copying a few disks from the CLI [shell] you can create your own Workbench disk. Its very easy. This morning I copied the files over from ARCADIA MultiDOS disk to my own Bench disk which involved LIBS,L,C and DEVS files and then from a simple command
PCMOUNTALL FROM devs:mountlist.multidos
I was able to mount both Df0 and Df1 as PC drives [ MD0 and MD1]. Better still with the command:
PCFORMAT DRIVE MD0: NAME [ dusk name ]
I was able to format a HD disk with the corner taped over and then could see that on a Windows PC. Amazing. You need SID or DOpus cus you can't see files without icons in 1.3 The software isn't suppose to work under WB 2.0 but I got it working on 1.3. I have photographed everything and will appear as a blog in a week or so.
MultiDOS came on a few cover disks.

So there is plenty around that will let you do it. Having a file manager like DOpus really helps seeing those files that are invisible to 1.3.
Using that FORMAT line I gave in my link may work on a USB drive. But with the PCFormat too in MultiDOS you don't need to. I didn't know if MultiDOS worked so I didn't suggest that one but if you see it going cheap I'd grab a copy.
Good luck
Er sorry almost forgot. Research creating your own self booting disk and the INSTALL command that prepares disks. You only need half a dozen files to create a self booting disk. Knowing how to do this and how to customise the disk thro the CLI [ shell ] is the way 1.3 works really. The basic 1.3 Workbench is very limited. It needs extra 'umph' to get it working to your benefit. Great fun.
