如何限制标准（非管理员）用户对 NTFS 分区的访问？

Question 1

使用以下命令打开 fstab 文件
```
gksudo gedit /etc/fstab
```
您应该在 /etc/fstab 文件中添加如下行，
```
/dev/sda7   /media/EXTRA    ntfs-3g noauto,uid=XXX,unmask=7 0   0
```
这XXX是我的用户 ID。您可以使用id命令找到您的用户 ID，这/dev/sda7是我想要限制访问的分区。
创建一个名为的文件夹EXTRA，/media/如下所示，
```
sudo mkdir /media/EXTRA
```
现在，无论何时登录，您都需要将其安装为，
```
sudo mount /dev/sda7 /media/EXTRA
```

完毕！

解释：
如果特定分区包含 VFAT 或 NTFS 文件系统，并且您只希望自己能够访问它，则非常简单：

在 fstab 行中包含选项"noauto", "uid=XXX", and "umask=7"并删除“用户”和/或“用户”选项（如果它们现在出现）。

这意味着在启动时系统将出现该分区卸载，并且只有您（以 root 身份操作，大概使用 sudo）可以挂载它。

一旦挂载，它将归您的非特权用户所有（假设该用户的 uid 为 XXX，该 ID 是在 MDV 安装中安装时创建的第一个用户 - 使用以该用户身份运行的“id”命令进行检查，并相应地调整 fstab），并且所有其他本地用户都无法访问。

通过发出mount四次命令来挂载您受限制的 4 个分区是一项无聊的任务。为了减少这项无聊的任务，我编写了一个 shell 脚本：

#!/bin/bash
#Mount Unmount secret partitions now with choice of partition
function checkPartitions(){
    local state=$1
    local dev=$2
    case $state in
    "unmounted")
        mount | grep -q $dev
        if [ $? -eq 1 ]; then
            echo $dev
        fi
        ;;
    "mounted")
        mount | grep -q $dev
        if [ $? -eq 0 ]; then
            echo $dev
        fi
        ;;
    esac
}

function safeUnmount() {
    local dev=$1
    mount | grep -q $dev
    if [ $? -eq 0 ]; then
        echo "Device $dev found. Unmounting now"
        sudo umount $dev
        if [ $? -eq 0 ]; then
            echo "Device $dev unmounted successfully."
        else
            echo "You are not root??"
        fi
    else
        echo "Device $dev is already unmounted."
    fi 
}

function safeMount() {
    local dev=$1
    mount | grep -q $dev
    if [ $? -eq 1 ]; then
        echo "Device $dev not found. Mounting now"
        sudo mount $dev
        if [ $? -eq 0 ]; then
            echo "Device $dev mounted successfully."
        else
            echo "You are not root??"
        fi
    else
        echo "Device $dev is already mounted."
    fi 
}

echo -e "What you want to do? \n 1. Mount Secret Partitions \n 2. Unmount Secret Partitions"
read -p "Enter your choice :" choice

case $choice in
1)
    echo -e "You want to Mount your secret partitions"
    echo "-------List of Unmounted secret partitions-------"
    checkPartitions "unmounted" "/dev/sdaX1"
    checkPartitions "unmounted" "/dev/sdaX2"
    checkPartitions "unmounted" "/dev/sdaX3"
    checkPartitions "unmounted" "/dev/sdaX4"
    anythingelse="y"
    #echo -e "\n"
    while [ $anythingelse == y -o $anythingelse == Y ]; do
        read -p "Which partition should be mounted?" partNum
            safeMount "/dev/sda"$partNum
        read -p "Do you want to mount any other partition? [y/n]" anythingelse
    done
    ;;
2)
    echo -e "You want to Unmount your secret partitions\n"
    echo "--------List of Mounted secret partitions--------"
    checkPartitions "mounted" "/dev/sdaX1"
    checkPartitions "mounted" "/dev/sdaX2"
    checkPartitions "mounted" "/dev/sdaX3"
    checkPartitions "mounted" "/dev/sdaX4"
    anythingelse="y"
    #echo -e "\n"
    while [ $anythingelse == y -o $anythingelse == Y ]; do
        read -p "Which partition should be unmounted?" partNum
            safeUnmount "/dev/sda"$partNum
        read -p "Do you want to unmount any other partition? [y/n]" anythingelse
    done
    ;;
esac

/dev/sdaX用 4 个分区替换。

另存为secret-mount-unmount.sh然后发出命令

chmod +x /path/to/file/secret-mount-unmount.sh

双击该文件然后点击Run in Terminal继续。

使用以下命令打开 fstab 文件
```
gksudo gedit /etc/fstab
```
您应该在 /etc/fstab 文件中添加如下行，
```
/dev/sda7   /media/EXTRA    ntfs-3g noauto,uid=XXX,unmask=7 0   0
```
这XXX是我的用户 ID。您可以使用id命令找到您的用户 ID，这/dev/sda7是我想要限制访问的分区。
创建一个名为的文件夹EXTRA，/media/如下所示，
```
sudo mkdir /media/EXTRA
```
现在，无论何时登录，您都需要将其安装为，
```
sudo mount /dev/sda7 /media/EXTRA
```

完毕！
