Physically install the hard drive.
After installing the drive, check the BIOS has detected your new drive with the correct size.
Identify the device
Check that the device has been detected by linux, then identify the device name.
root@turtle:~# ls /dev/sd* /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sdb
This shows a hard drive
sda with existing partitions
sda5. It also shows a hard drive
sdb, but with no
partitions detected. The new hard drive will have no partitions,
so we can identify it as device
fdisk is not an option
root@turtle:~# fdisk /dev/sdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0xbe043269. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable. Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) 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. Command (m for help): q
It tells us to use
parted with GPT format instead.
parted with gpt label
Create a partition using GPT format. I’ve chosen to use just 1 large partition that uses the whole disk.

Verify that the new partition appears as a device.
root@turtle:~# ls /dev/sd* /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sdb /dev/sdb1
The new partition
sdb1 has appeared.
Format the partition
I’m using the ext3 file system. Use
mkfs to format the drive.

Mount or add to /etc/fstab
root@turtle:~# mount /dev/sdb1 /mnt/sdb1/
The drive is now accessible via
You can also add the partitions to fstab.
