Listing All Physical Drives (Windows)

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.

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.

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;
}    

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