I am reformatting an older 40meg drive using gparted from within a Linux distro. The drive had no partitions and no partition table, so I am creating a new Partition Table via the Advanced option.
The default partition type is msdos, which I think is the same as MBR in parted. The description sounds right: maximum of 4 primary partitions, or 3 primary and 1 extended partition, maximum of 2 tb with 512b sectors.
There are a number of other options, gpt being one. Which I would use if the drive was greater than 2 tb.
The following partition types are also available: apx, amiga, bsd, dvh, mac, pc98, sun, loop.
The question: what are these other types and where can I find a description or discussion about them?
Secondary question: is there any reason to not use gpt on a smaller drive?
