Dear All,
In win2000, I can set the partition to Primary or Extended.
So
please suggest what is the difference between Primary and Secondary
Partition. And which one should I used it?
Thanks for your kindly attention.
1) A Primary partition can be made bootable; an Extended partition
cannot.
2) A Primary partition can contain only one logical drive; an
Extended partition can contain as many logical drives as you like,
limited only by the number of available drive letters.
Specifically, from WinXP's Help & Support's Glossary:
PRIMARY PARTITION. A type of partition that you can create on basic
disks. A primary partition is a portion of a physical disk that
functions as though it were a physically separate disk. On basic
master boot record (MBR) disks, you can create up to four primary
partitions on a basic disk, or three primary partitions and an
extended partition with multiple logical drives. On basic GPT disks,
you can create up to 128 primary partitions. Primary partitions are
also known as volumes.
EXTENDED PARTITION. A type of partition that you can create only on
basic master boot record (MBR) disks. Extended partitions are useful
if you want to create more than four volumes on a basic MBR disk.
Unlike primary partitions, you do not format an extended partition
with a file system and then assign a drive letter to it. Instead, you
create one or more logical drives within the extended partition. After
you create a logical drive, you format it and assign it a drive
letter. An MBR disk can have up to four primary partitions, or three
primary partitions, one extended partition, and multiple logical
drives.
