They are DD-DT. In this case, using fdcontrol to change the drive's settings is probably the correct way to go. Use the command % fdcontrol -F -v /dev/fd0 to see what drive and disk can tell about themselves. If that is not correct, use fdcontrol's -s option to change the drive's view. > OTOH, dd normally used to work on this kind of devices, didn’t it? If the (hardware) formatting deviates too much from what the drive's settings expect, it will only result in read errors. This where something within the chain "OS - controller - drive - medium" does not match the expectations. This is where fdcontrol can be used to change those expectations. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
