Last week I bought an external harddrive from best buy online (My Book, Western Digital, 250G). It came today! I was completely lost at first because I have both a Mac and a PC and there are different file systems you can format the harddrive in. There were all sorts of weird things I had to figure out, like FAT23 works on Mac and PC but you can only partition it at 32G for each partition, and alll sorts of other things. I was like, WTF?! I just want to put files on this damn thing, haha. But I now know how to format a harddrive and which system files work for what and pros and cons, so fun. Cumputers is fuuun.
