I can't fdformat the new formats. I have a Micron Millenia Transport. Either use mtools or mount the disk. It is a collection of utilities to access DOS disks. These utilities behave mostly like their DOS counterparts, i.e. mdir is like dir, mcopy is like copy, etc.
Specifics are in the manpages.
If you have a question or a bug report about the floppy driver, mail me at Alain. Then include the kernel messages as well as the application messages with your bug report. If you're using X windows, you won't see the kernel messages appear in your xterm window. Use dmesg to get them. Use dmesg also before executing the command, in order to find out which messages were generated by the command, and which ones were generated by earlyer commands.
