Just been doing some digging on this and have found out that a "pc style" partition map can have up to four primary partitions in it, but that the microsoft tools only allow the creation of 1 primary partition. Microsoft can use and read up to four primary partitions created by other tools. The notion of an extended partition was apparently a microsoft hack to get around the limitation of 4 primary partitions, and to allow its own tools to create more than 1 primary partition. The extended partition consumes the remainder of the disk space not consumed by the primary partition, and holds its own partition table to reference the "logical" drives as Brian points out. I've not discovered any limitation to the number of partitions / logical drives that an extended partition can have. Just some partition-trivia..... Sid. |
