How to measure hard disk capacity?

AlirezaH,

I would perform a WMI query for the instance of Win32_PhysicalMedia that
represents the actual drive and then check the Capacity property on it. You
can use the classes in the System.Management namespace to access this data.

Hope this helps.

This will do a little more:

using System;
using System.Management;

namespace sample {

/// <summary>
/// Displays disk space information for all connected hard drives.
/// </summary>
class freeSpace {

/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
public static void Main() {
string query = "select name, FreeSpace, Size from win32_logicaldisk
where drivetype=3";
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);

foreach(ManagementObject manobj in searcher.Get()) {
double freespace2 = double.Parse(manobj["FreeSpace"].ToString());
double disksize2 = double.Parse(manobj["Size"].ToString());
double pctfree2 = freespace2 / disksize2;
int lengthdiff = disksize2.ToString("N0").Length -
freespace2.ToString("N0").Length;

Console.WriteLine("For drive {0}", manobj["name"]);
Console.WriteLine("\tDisk size: " + disksize2.ToString("N0") + "
bytes");

/// <summary>
/// Format the free space line so the number lines up
/// right-justified with the disk size number
/// when using a fixed-width font.
/// </summary>
switch (lengthdiff) {
case 0:
Console.WriteLine("\tFree space: " + freespace2.ToString("N0") +
" bytes");
break;
case 1:
Console.WriteLine("\tFree space: " + freespace2.ToString("N0") +
" bytes");
break;
case 2:
Console.WriteLine("\tFree space: " + freespace2.ToString("N0")
+ " bytes");
break;
case 3:
Console.WriteLine("\tFree space: " + freespace2.ToString("N0")
+ " bytes");
break;
default :
Console.WriteLine("\tFree space: " + freespace2.ToString("N0") +
" bytes");
break;
}
Console.WriteLine();

Console.WriteLine("\tPercent free: " + pctfree2.ToString("P"));
Console.WriteLine();
Console.WriteLine();
}
}
}
}
