Problem Backing Up Master Boot Record

[adolfix]

I would like to make a back up of the MBR, just in case for security.

 

I login as root.

I format the disket with the command mformat a:

After, I do the command :

dd if=/dev/hda of=/dev/fd0/mbr.bin bs=512 count=1

The systems responds :

dd: ouverture de `/dev/fd0/mbr.bin': Not a directory

 

I then execute the command :

ls -l /dev/hda

the system responds :

brw-rw---- 1 root disk 3, 0 mai 5 09:32 /dev/hda

 

It seems it does not exist. What should I do ?

 

Thanks in advance for your help.
