device for build not in list

  • Dear all,


    I tried to build a Mirror "Raid". The devices are shown in physical disks (sdh and sdi), there I wiped them. When I now try to build the RAID, only one (sdi) of the 2 disks are shown in the list. They are both connected with USB on the system.


    The same is when I just try to make a new filesystem... in the drop down list is only sdi ... sdh is missing there, too.


    Where can be the problem? What can I do?


    Regards.

    It must not have wipe properly. I would - where sdX is the drive not showing up in the list:


    mdadm --zero-superblock /dev/sdX (this command may give error)
    dd if=/dev/zero of=/dev/sdX bs=512 count=10000

  • Thanks, that helps! Now the Raid is build!


    Can you say what that 2 lines are doing/mean?

    The first line would remove raid info if the drive had been in an array before. The second line zeros a lot of the info on the drive like boot sector, partition table, and other things that may make the drive appear to be in a previous array or already have a filesystem on it.
