Enumerate system drives in nodejs

All we need is an easy explanation of the problem, so here it is.

Is there a way to retrieve the drive name of all logical drives on a computer ?

I’ve looked at the fs api, but from there I can only enumerate the files and directories of a given directory.

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

I’m not sure what you mean by “drive name”. If you mean drives in the form of \\.\PhysicalDriveN, I faced the same problem and implemented this module that works in all major operating systems:

https://github.com/resin-io/drivelist

For Windows, you get information such as:

[
    {
        device: '\\\\.\\PHYSICALDRIVE0',
        description: 'WDC WD10JPVX-75JC3T0',
        size: '1000 GB'
    },
    {
        device: '\\\\.\\PHYSICALDRIVE1',
        description: 'Generic STORAGE DEVICE USB Device',
        size: '15 GB'
    }
]

Method 2

If you targeting on Windows, you could try this:

This solution base upon the idea from this post.

I wrap it with promise.

var spawn = require("child_process").spawn

function listDrives(){
    const list  = spawn('cmd');

    return new Promise((resolve, reject) => {
        list.stdout.on('data', function (data) {
            // console.log('stdout: ' + String(data));
            const output =  String(data)
            const out = output.split("\r\n").map(e=>e.trim()).filter(e=>e!="")
            if (out[0]==="Name"){
                resolve(out.slice(1))
            }
            // console.log("stdoutput:", out)
        });

        list.stderr.on('data', function (data) {
            // console.log('stderr: ' + data);
        });

        list.on('exit', function (code) {
            console.log('child process exited with code ' + code);
            if (code !== 0){
                reject(code)
            }
        });

        list.stdin.write('wmic logicaldisk get name\n');
        list.stdin.end();
    })
}

listDrives().then((data) => console.log(data))

Test it, you will see the result like:

["c:", "d:"]

Method 3

Based on Edwin Lees answer:

const child = require('child_process');

child.exec('wmic logicaldisk get name', (error, stdout) => {
    console.log(
        stdout.split('\r\r\n')
            .filter(value => /[A-Za-z]:/.test(value))
            .map(value => value.trim())
    );
});

Output: ['C:', 'D:'] etc.

Method 4

How about using the DiskPart command? Does running diskpart list in the command line give you the output you need? If so you can execute this in node using child_process.exec

var exec = require('child_process').exec
var cmd = 'diskpart list'
exec(cmd, function(err, stdout, stderr) {
    if (err) {
        console.log('error running diskpart list command')
        console.log(err)
        return
    }
    console.log('stdout data')
    console.log(stdout)

    console.log('stderr data')
    console.log(stderr)
})

Method 5

+1 for @Bagherani’s downgrade suggestion!

I am using Electron React Boilerplate v4.0 and could not get drivelist to load. I downgraded to [email protected] and it works for my needs.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
