    wholesale jewelry free shipping worldwide Before we add a hard disk, we must first understand the naming method of hard disks and partitions under the Linux system.

    The device for IDE under Linux is named after HD. The first IDE device is HDA and the second is HDB. Based on this type,

    The we usually have two IDE interfaces on the motherboard, and a total of four IDE devices can be installed. The two devices on the main IDE correspond to HDA ​​and HDB, respectively, and the two devices on the second IDE mouth correspond to HDC and HDD.

    The general hard disk is installed on the main interface of the main IDE, so it is HDA

    The optical drive is generally installed on the main connector of the second IDE, so it is HDC (should be in the The HDB is used to name the slave interface on the main IDE)

    SCSI interface device is named by SD, the first device is SDA, and the second is SDB. In this kind of push

    , the partition is named after the name of the device. For example, HDA1 represents the first partition on the HDA hard disk device.

    each hard disk can have a maximum of four main partitions, and the role is to name the main partition of the hard disk by 1-4. The logical partition starts from 5. Each more partition can be added.

    For example, our general system has a main partition to guide the system. This partition corresponds to the C -zone we often say, named HDA1 under Linux. Later, we are divided into three logical partitions D, E, F, and named HDA5, HDA6, HDA7 R

    Two partitions software FDISK and CFDISK

    For example, we already have a hard disk, and now add another hard disk to the system

    Then we know this newly added hard disk according to the naming rules. It's HDB. Let's use the following command to give the hard disk partition

    fdisk /dev /hdb

    You can also use CFDISK to partition, the command is as follows
    nCFDISK /DEV /HDB

    Format hard disk

    formatting into EXT3 format

    mkfs.ext3 /dev /hdb1
    n formatting into the format of Reiserfs

    mkfs.reiserfs/dev/hdb1

    letting the hard disk start automatically mount

    In vi editing/ETC/FSTAB file, add the following content

    /dev/dhb1/mnt/hd reiserfs defaults
