3.2.4.1.1 fdisk

I decide that I don't want to use the entire drive, so I'm going to partition it into 4 equal 2.5Gb primary partitions. They will become hdb1, hdb2, hdb3 and hdb4. I will use fdisk to partiton.

#fdisk /dev/hdb

The number of cylinders for this disk is set to 1653.

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)

Disk /dev/hdb: 255 heads, 63 sectors, 1653 cylinders

Units = cylinders of 16065 * 512 bytes

Using default value 1

Last cylinder or +size or +sizeM or +sizeK (1-621, default 621): +2.5M

First cylinder (413-1653, default 413):

Last cylinder or +size or +sizeM or +sizeK (413-1653, default 1653): +2.5Gb

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

I continue on in the same manner, creating the other two primary partitions, hdb3 and hdb4. When I have finished the partition table looks like this.

Disk /dev/hdb: 255 heads, 63 sectors, 1653 cylinders

I write out the drive partition with the 'w' command in Linux which brings me back to the prompt.
