I have some application programs for QNX in Diskette. How to make duplicate of diskette to new diskette ?
Insert original diskette
dd if=/dev/fd0 of=/tmp/diskette.dd
then
insert new diskette
dd if=/tmp/diskette.dd of=/dev/fd0
Format a blank disc with fdformat. Then all you have to do is copy the original disc image to a file, swap discs and copy the file to the new disc.
cp /dev/fd0 image.floppy
cp image.floppy /dev/fd0
Oh, and it’s a good idea to use -z2 or 3 in the fdformat options if the disc is to be bootable otherwise the boot time goes through the roof.
