I've been messing with an old Brother WP-2200 and I've hit a bit of a snag. I was hoping I would be able to make images out of the floppies I typed on it using dd under Linux. Unfortunately that hasn't worked. I've tried dd on about six different computers and they all have produced something similar to the following:
petrusd987@Peters-Gaming-Ubuntu:/tmp$ sudo dd if=/dev/zero of=/dev/sdd bs=1440k count=1 dd: writing to ‘/dev/sdd’: No space left on device 1+0 records in 0+0 records out 0 bytes (0 B) copied, 0.000530324 s, 0.0 kB/s
This also produces the same result when done in reverse. I don't understand why this is happening because I know for a fact that the floppy I used in the device was working perfectly under dd before the WP-2200 formatted it. I do know that these machines use a proprietary file system not recognized by computers if that helps anyone. I didn't think that mattered though because DD works at the binary level. Any help in fixing this would be greatly appreciated.
I didn't really word this post very well so I'd like to try to make it a bit clearer. The disk was not write protected when I was working with it. Below is three of the commands I have tried and the output I am given:
I would like to point out that the floppy has changed to sdb when I rebooted because I have removed my external hard drive and flash drive. **Copying: Writable** sudo dd if=/dev/sdb of=/tmp/flp.img 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.000530151 s, 0.0 kB/s **Erasing: Read-only** petrusd987@Peters-Gaming-Ubuntu:/tmp$ sudo dd if=/dev/zero of=/dev/sdb [sudo] password for petrusd987: dd: opening ‘/dev/sdb’: Read-only file system **Erasing: Writable** petrusd987@Peters-Gaming-Ubuntu:/tmp$ sudo dd if=/dev/zero of=/dev/sdb dd: writing to ‘/dev/sdb’: No space left on device 1+0 records in 0+0 records out 0 bytes (0 B) copied, 0.00111174 s, 0.0 kB/s
This is my problem. I'm assuming that it is attempting to append to the floppy. This is not what I want. I want it to start at the beginning of the floppy and write the zeros. How do I do this?
