Will using the drive without a partition table be harmful or are there disadvantages I should know about? The drive seems to be working just fine without a partition table, but I was just curious. I haven't tried gdisk yet, but I may keep that in mind for a rainy day. The disk I'm using houses all the tv shows and movies from my plex server so I can stream them over to my ps3 over my home network. it would be a bit of a pain to transfer the data off and back on again.
