sudo fdisk /dev/sdc



Welcome to fdisk (util-linux 2.27.1).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.



Device does not contain a recognized partition table.

The size of this disk is 5.5 TiB (6001175126016 bytes). DOS partition table format can not be used on drives for volumes larger than 2199023255040 bytes for 512-byte sectors. Use GUID partition table format (GPT).



Created a new DOS disklabel with disk identifier 0x2a4732aa.

How can i use other disks sdc, sdd, sdf ...
