It does appear so. That last line is exactly the desired effect (p 2 0x0c 64260 31182165). So it would seem that the "fdisk: Class not found" output is nothing more than a warning. Though, I'm with you -- it looks like an error. I'd be pretty interested to see the output "echo $?" after getting the "Class not found" message. That is to say, I wonder what the return status of fdisk is after receiving that message. It may be zero -- indicating success -- in which case we're reaffirmed that the output is completely spurious and able to be ignored. -- Devin > > Something you might also want to try is zapping the disk (wiping all > > contents) prior to trying again: > > > > dd if=/dev/zero of=/dev/da5 > > -- > Chris Hill chris@monochrome.org > ** [ Busy Expunging </> ] _____________ The information contained in this message is proprietary and/or confidential.
