Description Christian Sahle 2004-03-19 23:42:03 UTC 
If i load the Floppy with modprobe floppy i can see the following Kernel message:
Floppy drive(s): fd0 is 2,88M
FDC 0 is a post-1991 82077
         
2,88M ? My Floppy is 1,44M

O.K. module is load, so i send the command: mke2fs /dev/fd0 and all is good.
But if i make an mount /dev/fd0 /mnt/floppy i can only see:
