系统:Ubuntu + WindowsXP
硬盘: SDR(主) + SATA(从)
前段时间sata的硬盘坏了,拿去保修后回来,重新分区下,发现ubuntu下无法自动识别,后来找了些资料才知道,是需要重新挂载.
首先,找出系统标示的磁盘的 盘符/编号：
sudo lshw -C disk
---------得到输出------------
*-disk

--------------------------------------
我是sata的从盘无法识别,所以找出logical name:
/dev/sdb1
/dev/sdb5
/dev/sdb6
注意:
分区共有三种主分区、扩展分区和逻辑分区（如图）。在一个硬盘上主分区只有一个，扩展分区可以有三个，在Windows中只支持一个扩展分区，所以（在一个硬盘的情况下） Windows中D盘是扩展分区中的第一个逻辑分区。而在Linux中主分区和扩展分区用1～4来表示，而逻辑分区是从5开始编号的。因此，D盘在 linux中应该是hda5。如果第一个IDE硬盘并分为C、D、E、F四个分区，那么在Linux中则分别为hda1、hda5、hda6、hda7 了,hda2 其实是不存在的,他是hda6+hda7!
然后就可以挂载上去了，但是，这样挂载出来的分区是只读的，而且中文会出现乱码！！！
#新建一个文件夹,作为挂载点sda1 ,下同
sudo mkdir /media/sda1
#把第一个卷挂载到sda1上去,下同
sudo mount /dev/sdb1 /media/sda1
sudo mkdir /media/sda2
sudo mount /dev/sdb2 /media/sda2
sudo mkdir /media/sda3
sudo mount /dev/sdb5 /media/sda3
sudo mkdir /media/sda4
sudo mount /dev/sdb6 /media/sda4
如果需要让系统自动识别的话,可以编辑/etc/fstab
利用 ls -l /dev/disk/by-uuid/ 得到各个分区的编号
lrwxrwxrwx 1 root root 10 2007-10-08 10:04 1909-E93C -> ../../sda6
lrwxrwxrwx 1 root root 10 2007-10-08 10:04 338df5d1-66da-49ed-8d16-e2474c47352d -> ../../sda7
lrwxrwxrwx 1 root root 10 2007-10-08 10:04 411B-6DE9 -> ../../sdb1
lrwxrwxrwx 1 root root 10 2007-10-08 10:04 4703-EBB3 -> ../../sdb6
lrwxrwxrwx 1 root root 10 2007-10-08 10:04 4CDC-1AD6 -> ../../sda1
lrwxrwxrwx 1 root root 10 2007-10-08 10:04 8236-DBD6 -> ../../sdb5
lrwxrwxrwx 1 root root 10 2007-10-08 10:04 d25ac88b-4914-48c7-aa05-dbbe2074487e -> ../../sda8
lrwxrwxrwx 1 root root 10 2007-10-08 10:04 D2C7-6EE7 -> ../../sda5
然后到fstab里面把对应的项做修改
