I have this computer model: 17-inch MacBook Pro 2.6GHz Intel Core 2 Duo 4GB of RAM 200GB HD @ 7200-rpm What I need is a cheap External Hard Drive for now. I have found these 2 links: http://www.tigerdirect.com/applicat...tails.asp?EdpNo=3617642&body=MAIN#detailspecs SOLD OUT http://www.nowdirect.com/exec/partInfo/part_detail.tsb?prcpart=HMRHU1100-250 These 2 hard drives would be great for me. I only have 6GB left on my HD, and 12GB on my External HD. What I really need to know is if I can format these hard drives to Leopard. The main reason is because I have Final Cut Studio 2 and Logic Studio Pro. Thats about 100GB of Application data. If I could get Applications on an External HD, that would be great! I don't know if I just said everything correctly but I just need a External HD that can run Leopard.
