BE ABSOLUTELY SURE THAT YOU ARE RUNNING THESE COMMANDS AGAINST THE CORRECT DRIVE. WE CANNOT ACCEPT RESPONSIBILITY FOR ANY DATA LOSS, HARDWARE MALFUNCTION, ETC!

First we label the drive with a GPT partition

Now we select sectors as a unit of measurement

Now we make the partition.

Parted may complain about the last sector and will automatically suggest a correct sector, just say Yes to the prompt.

=Alternative Parted usage=

Instead of the sequence of one liners up there, you can enter into parted itself like this. I give this as I don't know how your version of parted is going to behave. The interactive stuff from parted has been removed:

=Format the drive!=

Finally, let's get that drive formatted to a nice ext4 volume:

=Adding to your HDA=

=A note about Western Digital drives=

Create a bootable usb drive using [http://www.freedos.org/freedos/files/ FreeDOS] and [http://unetbootin.sourceforge.net/ unetbootin], then copy wdidle.exe onto the usb drive. Boot up your Amahi box to FreeDOS and enter the following commands:

This cd's you to the usb drive's root, then we run wdidle3 /R to display the current drive status, then we run wdidle3 /S300 to set the park time to 5 minutes. Alternatively you could run wdidle3 /D to completely disable the parking.

n.b. Unetbootin was a bit finnicky for me, I found that if I created the drive with a FreeDOS live CD that it wouldn't work, but if I then re-created using unetbootin's automatic distribution download feature, the USB stick worked a treat. YMMV.

If you have a new hard drive you can add it now. Here are some instructions to use for 4TB HDD using partedto make sure the alignment is right. Example here is with a new HDD that appears as /dev/sdb (read here: http://rainbow.chard.org/2013/01/30/how-to-align-partitions-for-best-performance-using-parted/)

at the parted prompt

Formating the drive:

Mounting the drive:

Using the output from the above command, first backup /etc/fstab, and then add to /etc/fstab.

An example (and only an example!) of what needs to be added to /etc/fstab all on one line:
