The second hard disk is only used for an installation with RAID. If you have ordered an installation without RAID, the second hard disk is not used. If you want to use it, you must partition the hard disk, format it and integrate it into your system.


  1. Partition the hard disk
    fdisk /dev/sdb

    Press the following keys within the command interface:
    create a new partition key n
    Partition number Key 1
    Accept the default of the start cylinder Return
    Accept the default of the end cylinder Return
    Write partitioning Key w

  2. after successful partitioning, the hard disk must be formatted
    mkfs.ext4 /dev/sdb1

    Now the mount point of the hard disk (the directory under which it should be accessible) must be entered in /etc/fstab. Please note that the directory must exist beforehand. The entry could look like this, for example:

    /dev/sdb1 /Zweite-Festplatte ext4 acl,user_xattr 1 2

    Further information can be found, for example, on the page:


Under Windows, you can perform partitioning and formatting via the item:
Start => Computer management => Disk management.
Right-click on the unallocated memory and create a new simple volume.
