I'm looking to buy an external hard drive for my MacBook and have all three options available at the same price ($99) My options for the 250GB are.. 1. Western Digital My Passport Essential 250GB Portable Hard Drive http://www.circuitcity.com/rpsm/oid/201495/rpem/ccd/productDetail.do 2. Toshiba USB 2.0 Portable External 250GB Hard Drive http://www.circuitcity.com/rpsm/oid/204446/rpem/ccd/productDetail.do 3. Seagate® FreeAgent Go Portable External USB 2.0 Hard Drive, 250GB http://www.officedepot.com/a/products/403875/Go-Portable-External-USB-Hard-Drive/ I'm mostly looking for something that is easy to use and will withstand my 3 1/2 month study abroad trip. I heard some hard drives need to be formatted and such and I'm not too computer savvy so I'd rather not have to do all that stuff. I just want something that works well with my MacBook and that I can just plug in and use easily. Thanks in advance!
