Originally created by @lifepillar on GitHub (Aug 17, 2016).

I am having little luck mounting disk images. I have tried with several ones, standard ProDOS or DOS3.3 formatted, but in nearly all cases they are mounted as an empty volume. This is what I do:

Create an empty directory in my home directory;
Mount a disk image using profuse, using the above directory as the mount point.

I have tried with different combinations of the options. Since sometimes I do see an image mounted correctly, I guess that I am either using the wrong options or an unsupported format.

I attach an archive with a few examples: dusthead_v1.1.po and ROGUE.PO can be mounted correctly (without passing any additional options), but the remaining disk images are not. I am not getting any errors from profuse.

Using the current master and FUSE for OS X 2.8.3.

On OS X, it automatically creates a folder in /Volumes and mounts it in there so you don't need to worry about creating a directory for a mount point. Diags.do isn't a ProDOS disk. PRODOS copy.po looks like it's in DOS order (change the extension to .do or use the --format=do flag). The others mount fine for me.

Ah ok, now it's clear. Using the same directory for my all tests was not a good idea: I was probably leaving behind not cleanly unmounted volumes. Thanks!
