环境介绍
主机： XP
虚拟机：VirtualBox+Debian6
遇到的问题
我有一块西部数据的移动硬盘，虚拟机中有一些资料需要拷贝到移动硬盘中，然后我将移动硬盘插上后，执行如下设置，将移动硬盘分配给虚拟机：
然后就会将我的移动硬盘自动挂载到Debian中：
但是当我在/media/work下想创建一个文件夹时出现如下提示：
mkdir: 无法创建目录"debian_source": 只读文件系统
解决办法
安装工具：
sudo apt-get install ntfs-config
对linux系统而言，USB接口的移动硬盘是当作SCSI设备对待的。插入移动硬盘之前，应先用fdisk –l 或 more /proc/partitions查看系统的硬盘和硬盘分区情况。

接好移动硬盘后，再用fdisk –l 或 more /proc/partitions查看系统的硬盘和硬盘分区情况

大家应该可以发现多了一个SCSI硬盘/dev/sde和它的两个磁盘分区/dev/sde1、/dev/sde2,其中/dev/sde5是/dev/sde2分区的逻辑分区。有的系统支持自动挂载，可以通过mount命令查看自动挂载的目录：
pengdl@debian:~$ mount /dev/sda1 on / type ext3 (rw,errors=remount-ro) tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) udev on /dev type tmpfs (rw,mode=0755) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620) /dev/sdc5 on /home type ext3 (rw) /dev/sdb5 on /usr type ext3 (rw) /dev/sdd1 on /home/pengdl/ext_disk type ext3 (rw) rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) nfsd on /proc/fs/nfsd type nfsd (rw) share on /media/sf_share type vboxsf (gid=1001,rw) /dev/sde1 on /media/entertainment type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions) /dev/sde5 on /media/work type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions) pengdl@debian:~$
可以看到自动挂载到了/media/entertainment 和 /media/work下。进入/media/work下，发现已经可以执行写操作了。
对于不支持自动挂载的，需要进行手动挂载：
#mkdir -p /mnt/usbhd1
#mount -t ntfs /dev/sdc1 /mnt/usbhd1
注：对ntfs格式的磁盘分区应使用-t ntfs 参数。若汉字文件名显示为乱码或不显示，可以使用下面的命令格式。
#mount -t ntfs -o iocharset=cp936 /dev/sdc1 /mnt/usbhd1
