Ubuntu Linux mount移动硬盘、U盘、SD卡

首先将USB设备插到USB口上，我在我的机器上插入了一个USB硬盘，和一个SD卡，其中SD卡已经挂接到Ubuntu Linuxx系统。然后在终端中输入

$ sudo fdisk -l

会看到以下显示：

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x00000000

Device Boot Start End Blocks Id System
/dev/sdc1 1 2421 1984899+ 6 FAT16

其中：

Disk /dev/sdb: 120.0 GB是我的移动硬盘

Disk /dev/sdc: 2032 MB是我的SD卡

继续执行

$ mount

会看到一下显示

/host/ubuntu/disks/root.disk on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
/sys on /sys type sysfs (rw,noexec,nosuid,nodev)
varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755)
varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777)
udev on /dev type tmpfs (rw,mode=0755)
devshm on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
lrm on /lib/modules/2.6.24-19-generic/volatile type tmpfs (rw)
/host/ubuntu/disks/boot on /boot type none (rw,bind)
securityfs on /sys/kernel/security type securityfs (rw)
gvfs-fuse-daemon on /home/guandl/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=guandl)
/dev/sdc1 on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,shortname=mixed,uid=1000,utf8,umask=077,flush)

从以上内容可以看到/dev/sdc1（SD卡）挂接在/media/disk，下面我们将/dev/sdb1到Linux

首先创建一个挂接点，也就是目录

$ sudo mkdir /mnt/mvdisk-1

然后执行mount挂接

$ sudo mount /dev/sdb1 /mnt/mvdisk-1/

查看挂接点的内容

$ ls -l /mnt/mvdisk-1/

会看到类似一下内容

总用量 64

drwxrwxrwx 1 root root 61440 2008-09-23 20:43 books

drwxrwxrwx 1 root root 4096 2008-09-06 17:07 System Volume Information

再查看所有挂接设备

$ mount

/host/ubuntu/disks/root.disk on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
/sys on /sys type sysfs (rw,noexec,nosuid,nodev)
varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755)
varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777)
udev on /dev type tmpfs (rw,mode=0755)
devshm on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
lrm on /lib/modules/2.6.24-19-generic/volatile type tmpfs (rw)
/host/ubuntu/disks/boot on /boot type none (rw,bind)
securityfs on /sys/kernel/security type securityfs (rw)
gvfs-fuse-daemon on /home/guandl/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=guandl)
/dev/sdc1 on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,shortname=mixed,uid=1000,utf8,umask=077,flush)
/dev/sdb1 on /mnt/mvdisk-1 type fuseblk (rw,nosuid,nodev,noatime,allow_other,blksize=4096)

可以看到，/dev/sdb1已经挂接到了/mnt/mvdisk-1

断开挂接

$ sudo umount /mnt/mvdisk-1

再查看所有挂接设备

$ mount

/host/ubuntu/disks/root.disk on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
/sys on /sys type sysfs (rw,noexec,nosuid,nodev)

varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777)
udev on /dev type tmpfs (rw,mode=0755)
devshm on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
lrm on /lib/modules/2.6.24-19-generic/volatile type tmpfs (rw)

securityfs on /sys/kernel/security type securityfs (rw)
gvfs-fuse-daemon on /home/guandl/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=guandl)
/dev/sdc1 on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,shortname=mixed,uid=1000,utf8,umask=077,flush)

可以看到，/dev/sdb1已经不在挂接范围了
