I have recently purchased a 3TB WD Green hard drive and am trying to run it as internal storage. I am currently running Ubuntu 12.04 on a 250GB WD harddrive. The OS was just installed so nothing really has been altered.

I have tried to partition the drive using GParted and the command prompt but get errors either way.

I get a warning in the command prompt when I use sudo fdisk /dev/sdb as follows:

WARNING: The size of this disk is 3.0 TB (3000592982016 bytes). 
DOS partition table format can not be used on drives for volumes larger than 
 (2199023255040 bytes) for 512-byte sectors. 
Use parted(1) and GUID partition table format (GPT).

The device presents a logical sector size that is smaller than the physical sector size. Aligning to a physical sector (or optimal I/O) size boundary is recommended, or performance may be impacted.

This is my first time using a linux based system so unfortunately I don't know what to do from here.

Any suggestions would be greatly appreciated!

  • I have created two smaller partitions of type ext4. They have been mounted but I do not have privileges to write to the partitions. Any suggestions? – SDaigler Feb 3 '15 at 4:16
  • Try using Gparted, it should fix your issue. Past that just use GPT. – Virusboy Feb 3 '15 at 4:20

Warning: As this is a new drive, the following steps will delete everything on your drive!!!

Go to the dash and start gparted:

Parted screen

Then select the drive in the upper right corner (where on the picture you can see /dev/sde)

Go to the "Device" menu and choose "create partition table". (You will get a huge warning that this will delete your entire disk.) Click on the "Select new Partition table type" and take gpt.

And now you can do whatever you want! (including creating one huge partition)
