Hello David Barber, Adding some hints of what I think is going on inline below....

The syntax you're using is equivalent to: `fdisk -w -= -e -v -e -r /dev/sde` (and the wipemode argument `/dev/sde` does not match any of `auto`, `never` or `always) which is obviously not what you really want. Thus you get the above error message. (Additionally you're missing a target file but you never get that far in the parsing.) Hope this helps clear this one out. > root@vostro:/nas1/ISO-IMAGES# fdisk --wipe=never /dev/sde This one probably needs a bit deeper debugging to figure out. I would normally use `fdisk --wipe never /dev/sde` naturally, but you're not getting the previous error message so apparently separating option and optarg using = seems to be accepted syntax. Not sure what (if anything) goes wrong with this one. You write "does not honour the --wipe option" and it would be helpful if you could elaborate on what you expected and what happened. (It's not obvious to me from the below example.) Further investigation needed. > > Welcome to fdisk (util-linux 2.36.1). > Changes will remain in memory only, until you decide to write them. > Be careful before using the write command. > > The device contains 'iso9660' signature and it may remain on the device.

Using "reply all" in your mail user agent should do the right thing when replying.
