    blkid is already installed on your system. It's in the util-linux package which is the required part of every Ubuntu installation. Try
    Code:
    /sbin/blkid
    If you wonder what the command does: it prints block device identifiers.

    After zeroing I get the same result:
    I am asked to create a partition table, but that does not give any result.
    What now?

    Afterthought:
    Maybe I could clone another disk with the dd command?

    Did you remember to click on the tick icon at the top of the gparted window to confirm (and start) the actions?

    If the drive cannot be edited with gparted after zeroing, I think something is wrong with the drive.

    Yes it only costs your time to try
    Code:
    sudo dd if=/dev/sdx of=/dev/sdy bs=4096
    But in order to succeed, the data to be cloned should not extend the size of the target drive,160 GB. So make sure that the partitions on the source disk are not beyond that limit. And after the cloning you need to adjust the linux file systems with e2fsck and windows file systems from windows with chkdsk /f

    Many thanks to sudodus.
    That doesn't help either. I think I have spent enough time on the HD, after all it doesn't contain any data, so I will abandon ship.
    But I have learned a lot
    Also thanks to schragge for the input
    Best regards

    Eigil,

    There is a bug, that might affect you too. So your 160 GB drive might be OK. See this link

    I hope you have not thrown it away yet.

    Maybe it is time to try again according to findings of scruffyeagle.

    First you should update your system
    Code:
    sudo apt-get update
    Code:
    sudo apt-get upgrade
    And then try to make a partition table, partitions and file systems on your drive.
