since I got my Floppy Drive to be found by the system, I trouble with mounting it!

Some specs:

  • Ubuntu Server 16.04 LTS,
  • EIDE-Connected FDD,
  • installed packages for this subject: udisk2and fdutils

I also got the assumed entries in fstab 80-udisks2.rules , the floppy module is loaded and I also can format the disk via fdformat, but I cannot read it. Tried everything with root and as user in group "floppy"

Some results of commands I tried:

  • root@derinity:~# fdmount fdmount (/dev/fd0): Can't access /fd0: No such file or directory
  • root@derinity:~# udisksctl mount -p /dev/fd0 (udisksctl mount:1334): GLib-GIO-CRITICAL **: g_dbus_object_manager_get_object: assertion 'g_variant_is_object_path ( Error looking up object with path /dev/fd0
  • root@derinity:~# fdmount -l NAME TYPE STATUS fd0 1440K not mounted
  • root@derinity:~# fdformat /dev/fd0 Double-sided, 80 tracks, 18 sec/track. Total capacity 1440 kB. Formatting ... done1 Verifying ... Read: : Input/output error Problem reading track/head 0/0, expected 9216, read -1 [ADDED]



  • Are there any /dev/fd* entries? – Ignacio Vazquez-Abrams Feb 26 '18 at 18:21
  • Yes, /dev/fd0 – dor_ sax Feb 26 '18 at 18:28
  • You say you can format it, have you done so? Have you created a filesystem on the disk that can be mounted? – terdon Feb 26 '18 at 18:39
  • I added the Output of fdformat right now. I assume I din`t create a FileSystem? – dor_ sax Feb 26 '18 at 18:40

(This is from memory — I haven't had a floppy drive in nearly two decades.)

After formatting a floppy, it doesn't have a filesystem on it — so you need to create one before mounting it. E.g., to put a FAT filesystem on it, you'd do mkfs.vfat /dev/fd0 (plus any options for label, etc.) Or you could put ext2 on it with mkfs.ext2 /dev/fd0; ext3/4 is likely not possible because the journal is much larger than a floppy.

Then it ought to mount normally, e.g., with mount /dev/fd0 /media/floppy


Another option is to use superformat, which will format the floppy and create a DOS file system with the appropriate parameters (using mtoolsmformat); for example,

superformat /dev/fd0 hd

to format a 1440K disk.

However even fdformat should be able to verify your formatted floppy without problem, so there’s something else wrong somewhere...
