How to get logical drive letter from physical drive?

[galapogos]

Hi,
I'm wondering how I can get a drive letter from a physical drive name such as "\\.\PhysicalDrive2"?

Thanks. The article describes how to get the drive letter from a device path, such as "\Device\HarddiskVolume1" or "\Device\CdRom0". What I have is the "\\.\PhysicalDrive1" or "\\.\CdRom0". Is that actually the same, as in the numbers map exactly?

in c# very simple way

using (ManagementClass devs = new ManagementClass(@"Win32_Diskdrive"))
{
ManagementObjectCollection moc = devs.GetInstances();
foreach (ManagementObject mo in moc)
{
Console.WriteLine(mo["DeviceId"]);
foreach (ManagementObject b in mo.GetRelated("Win32_DiskPartition"))
{
Console.WriteLine("{0}", b["Name"]);
foreach (ManagementBaseObject c in b.GetRelated("Win32_LogicalDisk"))
Console.WriteLine("{0}", c["Name"]);
}
}
}

in VC++

One class is there Win32_LogicalDiskToPartition for this. you can have a look on that.

Thanks for the help anyway...anyone else? Could really use some help.

Edit: After some googling and trying out on my own, it would appear that \Device\\HarddiskX is the same as PhysicalDriveX. The code works! :)
