I recently got my hands on the Western Digital MyBook Live ( Amazon DE, Amazon US ). It is a 2 TB external harddrive that has only 2 connectors:
– A power supply
– A gigabit ethernet port

Initially, I wanted to use it as a no-hassle solution for OSX Time Machine backups. This worked perfectly and I can easily push 5-6 MB/s over Wifi to the drive. After being happy with this, I decided to see if there is anything else interesting going on with the drive.

Here are some findings: – The MyBook Live admin console is done in PHP using the full blown cakePHP framework:

– The MyBook Live has a hidden page to enable SSH at “/UI/ssh”:

– It has an 800MHz CPU with 256 MB RAM:
