Bear with me please - but I need advice. After a trip to the Genius bar today and finding out that I needed a new hard drive - I went to Best Buy and got a Sata 2.5 500 GB hard drive. I came home and carefully installed it ( static care) and then tried to install ( using the original discs ) my OS. It seemed to be doing okay but then when it came to choosing a destination - nothing, the screen just sat there. No messages - nothing, just that same screen asking me to choose a destination - there is nothing to choose. I have gone online and researched and am not sure, but am I supposed to format this and partition it ? And is this something over my head or if I carefully follow instructions - can I do this? Should I make another trip to the Genius Bar - ugh. This is what I have been reading: http://www.kenstone.net/fcp_homepage/partitioning_tiger.html thank you for time and attention - I am really frustrated - bad enough losing some programs and some things I didn't want to lose but now ? I am lost.
