Changing permissions

Postby ML2010 » Fri Jul 12, 2013 10:56 am

This is probably something which is easily rectified but I can't seem to find the answer in your index or elsewhere.
I need to boot an old laptop using floppy discs (yes, that old) as the laptop's CD drive is ignoring CDs. I know the floppy disk drive is working, and I want to use the Rawrite files available on your magazine's DVDs.
I'm using a desk top with an added FD drive and know that this machine's FD drive is working, being able to read an Abiword file from it. This machine is running Ubuntu 12.10.
On trying to drag the Rawrite files from the CD to the FD drive the message 'Error while copying - permission denied' pops up. I have changed the permissions by Rclicking on 'Properties' then opening 'Permissions', but the same message still pops up. What is it that I don't understand, please?

If you need to write an image to a floppy, use the dd command on the commandline, with sudo.
Code: Select all
sudo dd if=/path/to/floppy/image of=/dev/name-of-floppydrive

Thank you very much for your help so far. I have managed to have the desktop computer do something with the following command line instructions:

sudo dd if=/media/barry/LXFDVD166/Essentials/RAWRITE/rawwritewin.exe of=/floppy0

In the terminal it returned the following:

739+0 records in
739+0 records out
378368 bytes (378 kB) copied, 1.64695 s, 230 kB/s

There was however no floppy disk activity, and nothing appears to have been copied to the floppy disk.
I'm sure that is progress but I don't know what to do next, nothing I have researched seems to help.

Check the name of the destination, you probably need something like /dev/floppy0 or /dev/fd0 rather than /floppy0.

The chances are your command created a new file in the root of your hard disc called floppy0, hence it worked (no errors) but didn't touch the floppy disk.

Not wishing to state the obvious, but all of this is covered in the README.LXF file that accompanies the file you are trying to copy.
