The mount command has been unable to correctly mount a number of 1.44 MB floppies I have. I don't know why, because Windows can mount them just fine. I recently created a folder on one of them, too.
I don't know why this is happening, but I have verified many work via windows.Maybe if you use the proper command. How are you using DSL? Live/frugal: mount -t [fstype] /dev/fd0 /mnt/auto/floppy
You can also right click over a dfm desktop icon and select the mount points there for mounting and umounting. Helps to read the "getting started" document that comes up when you boot. Oh yeah, it also helps to check fstab and see where the mount points (if any) are set and double check permissions, etc. When you know what you're doing and that the permissions and fstype are right, you can mount the point directly (e.g., mount /mnt/auto/floppy).
