问题
When I open Disk Management
(right click My Computer->Manage) I see:
How can I know that path F:\
belongs to Disk5? In other words I will like to know what disks are available with C#.
The reason why I need to know that is because I have a usb mas storage device that is encrypted and I need to pass the parameter \Device\Harddisk5
to TrueCrypt along with the password in order to mount the encrypted device with code.
Edit
I know how to look the drives info. I just dont konw how to know that Drive 1 belongs to disk 0 for instance. In other words I am having trouble figuring out the Disk Number. I am looking to implement:
public string GetDiskNumber(char letter)
{
// implenetation
return Disk5;
}
where I will call that as:
GetDiskNumber('F');

You can use WMI to retrieve that information
System.Management.ManagementObject("Win32_LogicalDisk.DeviceID=" & DriveLetter & ":")
See more at Win32_LogicalDisk class I hope it helps. By the way there is PInvoke too GetVolumeInformation.
If you need 'PHYSICALDRIVE0' you should use Win32_PhysicalMedia class and the class Win32_DiskDrivePhysicalMedia glue both.
An exemple of your need in C#
public string GetDiskNumber(string letter)
{
var ret = "0";
var scope = new ManagementScope("\\\\.\\ROOT\\cimv2");
var query = new ObjectQuery("Associators of {Win32_LogicalDisk.DeviceID='" + letter + ":'} WHERE ResultRole=Antecedent");
var searcher = new ManagementObjectSearcher(scope, query);
var queryCollection = searcher.Get();
foreach (ManagementObject m in queryCollection)
{
ret = m["Name"].ToString().Replace("Disk #", "")[0].ToString();
}
return ret;
}

Have made a method for you gets drive letter and its number in a dictionary;
public Dictionary<string, string> GetDrives()
{
var result = new Dictionary<string, string>();
foreach ( var drive in new ManagementObjectSearcher( "Select * from Win32_LogicalDiskToPartition" ).Get().Cast<ManagementObject>().ToList() )
{
var driveLetter = Regex.Match( (string)drive[ "Dependent" ], @"DeviceID=""(.*)""" ).Groups[ 1 ].Value;
var driveNumber = Regex.Match( (string)drive[ "Antecedent" ], @"Disk #(\d*)," ).Groups[ 1 ].Value;
result.Add( driveLetter, driveNumber );
}
return result;
}
