"fdisk -l" output: what are Disk label type" and "Disk identifier" `fdisk -l` output: . . Disk label type: dos Disk identifier: 0x0006a8bd . . What are `Disk label type` and `Disk identifier`? Also, apart from the manuals, where else can I find more information about disk management / partitioning etc..?

The disk label type is the type of Master Boot Record. See < The disk identifier is a randomly generated number stuck onto the MBR.

In terms of tools for looking at disks, fdisk is on its way to being deprecated if it isn't already so. `parted` is the replacement for `fdisk` and `gparted` can be used to provide a graphical interface to parted (although certainly other tools exist as well).
