Hi, I have just bought this HDD http://www.amazon.co.uk/Western-Digital-MyBook-External-FireWire/dp/B002T492CM/ref=sr_1_6?ie=UTF8&qid=1307626339&sr=8-6 and Just want to know if a few things are possible. This HDD will primarily be used for Time Machine and I want to dedicate 750gb to it and then use 750gb for other stuff. Does anyone know anything about this HDD, if it can be partitioned in to 2 separate drives or if not and it only stays as 1 drive will it be ok to use TM on it along with other file storage? Also this HDD will only be used for my 1 mac book pro and nothing else as it is a music editing machine and I need constant back ups. Thanks.
