I’m using the supply that came with the system.
I got it to boot by removing the the ext4 partition.
I verified the drive works by running hdparm -tT on it:
root@tegra-ubuntu:~# hdparm -tT /dev/sda
Timing cached reads: 3978 MB in 2.00 seconds = 1991.38 MB/sec
Timing buffered disk reads: 764 MB in 3.00 seconds = 254.54 MB/sec
I copied the whole of the /home/ubuntu folder on to it and it worked perfectly. (2.2 Gigs)
Here’s the drive info:
root@tegra-ubuntu:/mnt/ssd# smartctl -i /dev/sda
smartctl 6.2 2013-07-26 r3841 [aarch64-linux-3.10.67-g458d45c] (local build)

It is odd because it’s an MSATA device plugged into a regular SATA converter board, but it has worked for me like this in all other cases.
I’m going to reboot now and verify that with the ext4 partition, it won’t boot anymore.
