Create a normal floppy with dd?

I am trying to create a normal in size floppy disk with
dd using the following
Code: Select all
dd if=/dev/zero of=os.img count=1440 bs=512
dd if=boot.bin of=os.img bs=512 count=1
dd if=kernel.bin of=os.img bs=512 seek=1
However, the resulting floppy is only 6Kb in size, which Virtual Box won't accept. Any ideas?
Thanks in advance!

Oh...
man dd wrote:Code: Select all
conv=CONVS
convert the file as per the comma separated symbol list
[...]
Each CONV symbol may be:
[...]
notrunc
do not truncate the output file
tl;dr: by default dd truncates output file, so you should specify conv=notrunc option.
