Figure 2-2: Partition your disk during installation from the Disk Setup window.
For each of the hard disk partitions, you can see:
Device — The device name is the name representing the hard disk partition in the /dev directory. Each disk partition device begins with two letters: hd for IDE disks, sd for SCSI disks, ed for ESDI disks, or xd for XT disks. After that is a single letter representing the number of the disk (disk 1 is a, disk 2 is b, disk 3 is c, and so on). The partition number for that disk (1, 2, 3, and so on) follows that.
Mount Point/Raid/Volume — The directory where the partition is connected into the Linux file system (if it is). You must assign the root partition (/) to a native Linux partition before you can proceed. If you are using RAID or LVM, the name of the RAID device or LVM volume appears here.
Type — The type of file system that is installed on the disk partition. In most cases, the file system will be Linux (ext3), Win VFAT (vfat), or Linux swap.
However, you can also use the previous Linux file system (ext2), physical volume (LVM), or software RAID.
Format — Indicates whether (check mark) or not (no check mark) the installation process should format the hard disk partition. Partitions marked with a check are erased! So, on a multiboot system, be sure your Windows partitions, as well as other partitions containing data are not checked!
Size (MB) — The amount of disk space allocated for the partition. If you selected to let the partition grow to fill the existing space, this number may be much larger than the requested amount.
Start / End — Represents the partition's starting and ending cylinders on the hard disk.
In the top section, you can see each of the hard disks that are connected to your computer. The drive name is shown first. The Geometry section (Geom) shows the numbers of cylinders, heads, and sectors, respectively, on the disk. That's followed by the model name of the disk. The total amount of disk space, the amount used, and the amount free are shown in megabytes.
Reasons for partitioning
There are different opinions about how to divide up a hard disk. Here are some issues:
Do you want to install another operating system? If you want Windows on your computer along with Linux, you will need at least one Windows (Win95 FAT16 or VFAT type), one Linux (Linux ext3), and one Linux swap partition.
Is it a multiuser system? If you are using the system yourself, you probably don't need many partitions. One reason for partitioning an operating system is to keep the entire system from running out of disk space at once. That also serves to put boundaries on what an individual can use up in his or her home directory (although disk quotas are good for that as well).
Do you have multiple hard disks? You need at least one partition per hard disk. If your system has two hard disks, you may assign one to / and one to

/home (if you have lots of users) or /var (if the computer is a server sharing lots of data).
Deleting, adding, and editing partitions
Before you can add a partition, there needs to be some free space available on your hard disk. If all space on your hard disk is currently assigned to one partition (as it often is in DOS or Windows), you must delete or resize that partition before you can claim space on another partition. The section on reclaiming disk space discusses how to add a partition without losing information in your existing single-partition system.

The Disk Druid is less flexible, but more intuitive, than the fdisk utility. Disk Druid lets you delete, add, and edit partitions.
