Debian Linux Wheezy: Partitioning 3TB Hard Drives with GPT Table (fdisk show 2TB max.)

Problem: On Debian Linux the brand new 3TB SATA Drives only seen as 2TB Drives by fdisk

Background: GPT Partition Table must be used as new technology

Solution:

  • install „gdisk“ the GPT Tool for big Drives with #sudo aptitude install gdisk
  • clean the new Drives first Table Headers with #sudo dd if=/dev/zero of=/dev/sdb count=1 bs=512
  • run now #sudo sgdisk /dev/sdb
  • Command is „sgdisk“ not „gdisk“ = its Paket Name
  • same on other Linux/BSD Systems on Windows use Paragon Tools
