列出所有物理驱动器（Windows） [英] Listing All Physical Drives (Windows)

问题描述

我怎样才能得到所有的物理驱动器路径（\\\\。\\ PhysicalDriveX）在Windows计算机上，用C / C ++？

How can I get all the physical drive paths (\\.\PhysicalDriveX) on a Windows computer, with C/C++?

在这个问题建议让逻辑驱动器盘符，然后让对应于安装驱动器的物理驱动器。问题是，我想要得到的所有的
物理驱动器连接到电脑上，包括未安装的驱动器。

The answers in this question suggest getting the logical drive letter, and then getting the physical drive corresponding to that mounted drive. The problem is, I want to get all physical drives connected to the computer, including drives that are not mounted.

其他答案建议从0-15递增值，如果一个驱动器存在有检查（\\\\。\\ PhysicalDrive0，\\\\。\\ PhysicalDrive1，...）或调用WMIC列出所有驱动器。[

Other answers suggest incrementing a value from 0-15 and checking if a drive exists there (\\.\PhysicalDrive0, \\.\PhysicalDrive1, ...) or calling WMIC to list all the drives.[

由于这些看起来他们会的工作，他们似乎像他们根本没把最好的办法。有没有 GetPhysicalDrives 一个简单的函数，这样只是返回的std ::字符串的包含路径的矢量所有的物理驱动器？

As these seem like they would work, they seem like they are not the best approach to be taking. Is there not a simple function such as GetPhysicalDrives that simply returns a vector of std::string's containing the paths of all the physical drives?

推荐答案

您可以使用 QueryDosDevice 。根据描述，你期望这个名单之类的东西 C：和 D：，但它也将列出的东西像 PhysicalDrive0 ， PhysicalDrive1 等。

You can use QueryDosDevice. Based on the description, you'd expect this to list things like C: and D:, but it will also lists things like PhysicalDrive0, PhysicalDrive1 and so on.

主要的缺点是，它也列出了很多你可能不关心其他设备的名称，所以（比如）我的机器上，我得到的近600设备名称列表，其中只有一个相当很小的比例是关系到你关心的东西。

The major shortcoming is that it will also list a lot of other device names you probably don't care about, so (for example) on my machine, I get a list of almost 600 device names, of which only a fairly small percentage is related to what you care about.

万一你关心，一些（旧）样本code：

Just in case you care, some (old) sample code:

#define WIN32_LEAN_AND_MEAN
#include <windows.h>

#include <iostream>

int main(int argc, char **argv) {

    char physical[65536];
    char logical[65536];

    if ( argc > 1) {
        for (int i=1; i<argc; i++) {
            QueryDosDevice(argv[i],logical, sizeof(logical));
            std::cout << argv[i] << " : \t" << logical << std::endl << std::endl;
        }
        return 0;
    }

    QueryDosDevice(NULL, physical, sizeof(physical));

    std::cout << "devices: " << std::endl;

    for (char *pos = physical; *pos; pos+=strlen(pos)+1) {
        QueryDosDevice(pos, logical, sizeof(logical));
        std::cout << pos << " : \t" << logical << std::endl << std::endl;
    }    

    return 0;
}    

但是，如果我运行这个像`devlist | grep的^物理，它列出了物理驱动器。

However, if I run this like `devlist | grep "^Physical", it lists the physical drives.
