I thought about buying one until I saw that Seagate makes it, DO NOT BUY A SEAGATE HARD DRIVE!
Seagate made the HD for the MacBooks that all had problems with crashing. I worked at Apple for a short time and everyone I worked with that had a macbook had their drive crash at some random time, mine happened to be 1 year and 4 months. Another girl that worked there had hers go out after 4 months. Luckily for me, I had leopard 2 weeks prior and got everything backed up.
