John has an old Vista laptop he's going to put Ubuntu on. Before he does, he wants to backup all of his photos. What drive should he buy? Leo says he'll want an NTFS drive that also handles FAT32 for Mac and EXT3 for Linux. Everything can read FAT32, so he can just leave the format that way. Macs have trouble with NTFS. The downside of FAT32 is that none of his files can be larger than 2GB.
