Problem trying to read raw data off of floppy

[philp]

Hi
I am trying to read data from a 3 1/4 inch floppy. I have been told that it has 64 tracks of 32 sectors. I have tryed using the commands

dd if=/dev/fd0 of=/tmp/a
or
dd bs=2048 if=/dev/fd0 of=/tmp/a

but I get the error
dd: reading `/dev/fd0': Input/output error
0+0 records in
0+0 records out

Do I need to use setfdprm to try and set-up other parameters or is there another method that I could try and use?

Any suggestions would be welcome
Thanks

You can use the noerror switch to continue reading after errors.
Check the man pages but I think it goes like this:

dd conv=noerror    <other arguments>
