I have an external USB drive with 2.0 TB connected to a machine running Ubuntu Server 14.04.

I used:

fdisk -l

and I can see that my at dev/sdd1. Here is the output:

WARNING: GPT (GUID Partition Table) detected on '/dev/sdd'! The util fdisk doesn't support GPT. Use GNU Parted.

Disk /dev/sdd: 2000.4 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors

Disk identifier: 0x00000000

Device Boot Start End Blocks Id System
/dev/sdd1 1 3907029167 1953514583+ ee GPT

I mount it using:

sudo mount /dev/sdd1 /media/Backup

And when I use df -h this is what I get:

/dev/sdd1 190M 1.6M 175M 1% /media/Backup

As you can see the drive size is 2 TB but I'm only getting 190 MB. I'm fairly new to Ubuntu and linux so excuse my ignorance.

Any suggestions?

  • Welcome to Ask Ubuntu! ;-) Could you please give us a bit more information like: what version of Ubuntu you're running? And a screen shot of gparted? Please edit your question and add this information... – Fabby Mar 19 '15 at 22:20

Did you try actually copying a Gb of info there? It can be a bug in df only. Did you try reformatting HDD? By the way, check the size in GParted or any other tool that really understands GPT. Re-create GPT table using GParted, the create partition. If this disk is linux-only, use btrfs file system, otherwise you have to use NTFS.
If after recreating GPT you still see small size in GParted, you disk is damaged or fake.

The Error fdisk is giving you is that it doesn't understand gpt partition tables. This means you need a different piece of software the guy above said using gparted but if u don't have a gui u must type in terminal

parted

after u must type

print all

This will shows all hard drive info. This will also all the partitions like fdisk
