Hi,

Yes, 4 and 5 should be the same, because sda4 is the EXTENDED PARTITION
which holds all LOGICAL VOLUMES sda5-256 within it. sda4 is a MANAGEMENT
PARTITION TABLE
and is not accessable (and shouldn't be accessed). Only the Logical Drives
within sda4 are accessable.

In the PC-BIOS world you are permitted 4 PRIMARY (Bootable) Partitions. If
you want more than 4 partitions,
then you sacrifice one of the Primary Partitions and make it the Extended
Partition which holds all the Logical Volumes from 5 up to a max of 256 I
believe. Partitions in the Extended Partition are not bootable.

Hope this helps.

Andrew Campagnola

Please look at my fdisk, I think it looks pathetic! First of all, it looks
like sda4 and sda5 is starting at the same place? I have two swaps, I
remember adding only one.
All I wanted to do is have a boot partition, a / partition, and possibly a
/home partition. Maybe I should reinstall. Any advice would be greatful.


# fdisk /dev/sda

The number of cylinders for this disk is set to 4420.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p
