Hey all, I currently have a first gen 15" unibody MBP. After filling up the 250 gb internal drive pretty quickly I purchased a 500 gb seagate drive to replace it. I plan on purchasing this enclosure for the drive I remove from the computer. My first question is does any body have any experience with that enclosure? Will my 15" MBP be able power the drive over a single USB cable? Secondly, if that enclosure will work as I want it to, will I then be able to retrieve all of my data off of it when I connect it via USB? I've started pulling some of my pictures and other data off the internal drive but I will be unable to fit all of my iTunes library onto my existing external. Thanks in advance.
