Format hard disk using fdisk partition on linux

Linux platform uses fdisk partitioning to Format hard disks-general Linux technology-Linux technology and application information. The following is a detailed description. Format and partition

Hd-IDE device sd-SCSI Device

Fdisk-l/dev/sda view the first hard disk partition

Fdisk/dev/sdb partitions the second Hard Disk

Command acton (m for help): m # displays the command list

A-set the bootable flag; B-set the volume label; d-delete a partition; n-create a partition.

P-display partition information; v-verify Partition Table; q-do not save disk exit; w-save disk exit; t-change partition type

Command acton (m for help): n creates a partition.

Command action

E extended # extended partition

P primary partition (1-4) # primary partition

P # create a primary Partition

Partition number (1-4): 1 # create the first primary partition

First cylinder (1-522, default 1): 1 # Start cylindrical (the first partition is always 1)

Last cylinder or + size or + sizeM or + siezK (1-522, default 522): 10 # End cylindrical (if 522, the entire hard disk is allocated to a zone) the partition size is automatically calculated by the system based on the cylindrical size.

Command acton (m for help): n

Command action

E extended

P primary partition (1-4)

P

Partition number (1-4): 2 # create the second primary partition

First cylinder (11-522, default 11): 11

Last cylinder... (11-522, default 522): + 100 M # custom partition size

Command acton (m for help): n

Command action

E extended

P primary partition (1-4)

E # create an extended partition. Note that only one extended partition can be created for one disk.

Partition number (1-4): 3

First cylinder (28-522, default 28): 28

Last cylinder... (28-522, default 522): 522 # allocate all the remaining space to the extended partition

Extended partitions cannot be used directly. You must create logical partitions on them!

Command acton (m for help): n

Command action

L logical (5 or over) # logical Partition

P primary partition (1-4)

L

First sylinder (28-255, default 28): 28 # create a logical partition in the extended partition

Last cylinder... (28-522, default 522): 522 # The number of cylinders is exhausted, which means only one logical partition is created.

Command acton (m for help): w # Save and exit

Convert partition type:

Command acton (m for help): t # convert the partition type

Partition number (1-4): 2 # select the second primary partition

Hex code (type L to list codes): 82 # encoding corresponding to the partition type can be listed by L

Format and mount: (you can create or specify an empty directory)

Mksf. ext3/dev/sdb1 format the first primary partition of the second hard disk as ext3

Mkswap/dev/sdb2 initializes the swap zone, which cannot be formatted.

Mount/dev/sdb1/mnt/d # mount the first partition to the d directory.

Automatic mounting after restart: vi/etc/fstab

Add:/dev/sdb1/mnt/d ext3 default 0 0
