Logical Partition
On an x86 system, a sub-partition of an extended partition. Linux systems can typically use extended partitions, whereas Solaris and BSD systems cannot.

Linux uses a sometimes confusing numbering scheme for the primary and logical partitions on a disk. The primary partitions are numbered 1-4 and the logical partitions are numbered starting with 5. A typical disk named /dev/hda, with extended partition 2, broken up into 1000-cylinder partitions, might look like this:

Primary Partition Logical Partition Linux name cylinders notes
primary 1   /dev/hda1

1-1000

usually windows C:
primary 2   /dev/hda2

1001-5000

don't use
  logical 1 /dev/hda5

1001-2000

often windows D:
  logical 2 /dev/hda6

2001-3000

maybe windows E:
  logical 3 /dev/hda7

3001-4000

 
  logical 4 /dev/hda8

4001-5000

 
primary 3   /dev/hda3

5001-6000

 
primary 4   /dev/hda4

6001-7000
