Total size of a harddisk

There are a few articles about this here on Codeproject:

The best one I found is this (C++)
Get Physical HDD Serial Number without WMI[^]

Or this one using C#
How to Retrieve the REAL Hard Drive Serial Number[^]

This will give you a list of physical disks and some properties about each one.


And heres a simple script using WMI:

var searcher = new ManagementObjectSearcher(@"select * from Win32_DiskDrive");
foreach (ManagementObject obj in searcher.Get())
{
    Console.WriteLine("Name:{0}", obj["Name"]);
    Console.WriteLine("Size:{0}", obj["Size"]);
}

Hi,

try with DriveInfo Class.
DriveInfo (Properties)[^]
DriveInfo.TotalSize[^]

try like below.

System.IO.DriveInfo info = new System.IO.DriveInfo();
Console.WriteLine(info.TotalSize); // gets the total size of the drive.

hope it helps.

You need to use the DriveInfo Class. Here is the MSDN DriveInfo Class link[^].

An example code:

using System;
using System.IO;

class Info {
    public static void Main() {
        DriveInfo[] drives = DriveInfo.GetDrives();
        foreach (DriveInfo drive in drives) {
            Console.WriteLine(drive.Name);
            if (drive.IsReady) Console.WriteLine(drive.TotalSize);
        }
    }
}

Good luck,
OI
