Format the hard disk with Fdisk partition on Linux

Article Title: format the hard disk with Fdisk partition on the Linux system platform. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic classification formatting and partitioning
　
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 # It means that 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
