Linux下的分割區相對Windows而言要稍微複雜一點，下面就由我給大家帶來在Linux下新新增硬碟，分割區並實現系統啟動時自動掛載的過程
1
檢查發現系統上目前並沒有掛載新的硬碟，如下圖所示：
2
新增硬碟後我們啟動電腦並再次檢查，我們可以看到最下面多了一行「Disk /dev/sdb doesn't contain a valid partition table」，告訴我們有一塊新的硬碟，但是還沒有分割區；如下圖所示：

根據以上提示開始對新的硬碟進行分割區操作，由於截圖比較麻煩所以呢我把命裡copy出來了，需要操作的部分我會標記出來[root@Linux ~]#?fdisk /dev/sdb?? ??? ?//根據提示,對新硬碟進行分割區操作Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding a new DOS disklabel.

完成以上操作後我們可以看到新新增的硬碟已經存在分割區了

下面對分割區進行格式化操作：[root@Linux ~]#?mkfs -t ext3 -c?/dev/sdb1?? ?//對分割區使用 ext3 格式化，如果建立了多個分割區，顯示 /dev/sdb2、/dev/sdb3 等，以此類推，重複輸入這條命令，就可以進行其它分割區的格式化操作了。因為新硬碟加了-c引數，要先檢測磁碟壞軌，因此，這個過程全有些長，需要耐心等待……注意這裡的時間長短時根據你的硬碟大小來實現的，如果硬碟大時間就會久一些，否則就會小短一些mke2fs 1.39 (29-May-2006)Filesystem label=OS type: LinuxBlock size=4096 (log=2)Fragment size=4096 (log=2)1310720 inodes, 5241198 blocks131029?blocks (5.00%) reserved for the super userFirst data block=0Maximum filesystem blocks=0160 block groups32768 blocks per group, 32768 fragments per group16384 inodes per groupSuperblock backups stored on blocks:???????? 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632Checking for bad blocks (read-only test): done ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?Writing inode tables: done ? ? ? ? ? ? ? ? ? ? ? ? ? ?Creating journal (32768 blocks): doneWriting superblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 32 mounts or180 days, whichever comes first.?

開始對分割區進行掛載使用，首先建立一個用於掛載的目錄

輸入vim /etc/fstab進行編輯，並在該檔案內輸入以下內容，然後在：wq儲存並退出，重新啟動驗證即可
