My wife needs to back up her MacBook Pro 5.5 running Mac OS X 10.5.8. I bought an Omega Desktop DH (2 TB) for her for Xmas. The box indicates you must reformat for use with Mac. 1. I am thinking this should only take a short while to reformat and then this drive will be as good as other more expensive "Apple" drives, correct? 2. Does Apple supply good software for backing up or should I use some other software? 3. As a "non-Mac" guy, is there anything else I should know or do? Thanks for the help as I do not want to open the box if I need to return it for something else.
