I bought 2 of these portable USB 3.0 MiniStation 2TB Buffalo I bought 2 of these external hard drives. I use them on both PC and Mac. The trick to using them on both PC and MAC is to format them as EX-FAT. I don't fully trust any external hard drive, so I always back up my data to another external hard drive just in case. It's also a good idea to back up your data to the cloud.
