Hi, Richard!
It seems that this limitation (IF Len(id) > 11) is obsolete.
According to the example in MS.W7SDKCOM (Win32_PhysicalMedia Class);
....
SerialNumber
Data type: string
Access type: Read-only

Manufacturer-allocated number used to identify the physical media.

Example: WD-WM3493798728.
I failed to find the length of this string (SerialNumber), but the
given example is 15 characters long. In this case your routine will
obviously fail while comparing two numbers.
Maybe it is useful to make buffer as long as MAX_PATH and then Rtrim
it.
HTH.

Good idea.

Richard,

I need to correct something here. The number return here is NOT the disk
serial number but the volume number - which is something Windows assigns
the drive (and virtual drives etc) when they are created.

The "serial" number is something else.

The Volume number is always a number and always <4GB.
It has a maximum length of 10 digits.

Geoff

PS - you can get the SERIAL number in C# like this:

//Namespace Reference
using System.Management

/// <summary>
/// method to retrieve the selected HDD's serial number
/// </summary>
/// <param name="strDriveLetter">Drive letter to retrieve serial number
for</param>
/// <returns>the HDD's serial number</returns>
public string GetHDDSerialNumber(string drive)
{
//check to see if the user provided a drive letter
//if not default it to "C"
if (drive == "" || drive == null)
{
drive = "C";
}
//create our ManagementObject, passing it the drive letter to the
//DevideID using WQL
ManagementObject disk = new
ManagementObject("win32_logicaldisk.deviceid=\"" + drive +":\"");
//bind our management object
disk.Get();
//return the serial number
return disk["VolumeSerialNumber"].ToString();
}

Geoff,

Here is the Vulcan version of your function for all the folks who want
to call this from Vulcan without creating the c# dll. Thanks for posting
your snippet. It was very handy!!

Regards,
Willie

// Application : SerialNumber
// start.prg , Created : 3/6/2010 6:35 AM
//Namespace Reference
#USING System.Management
#USING System.Windows.Forms
FUNCTION Start() AS VOID
LOCAL cSerial AS STRING
TRY
cSerial := GetHDDSerialNumber("C")
MessageBox.Show(cSerial)
CATCH ex AS Exception
MessageBox.Show(ex:ToString())
END TRY
RETURN
/// <summary>
/// method to retrieve the selected HDD's serial number
/// </summary>
/// <param name="strDriveLetter">Drive letter to retrieve serial number
for</param>
/// <returns>the HDD's serial number</returns>
FUNCTION GetHDDSerialNumber(drive AS STRING)
LOCAL disk AS ManageMentObject
//check to see if the user provided a drive letter
//if not default it to "C"
IF drive == "" .or. drive == NULL
drive := "C"
ENDIF
//create our ManagementObject, passing it the drive letter to the
//DevideID using WQL
disk :=
ManagementObject{String.Concat("win32_logicaldisk.deviceid="+chr(34),
drive, ":"+chr(34))}
//bind our management object
disk:Get()
//return the serial number
RETURN disk["VolumeSerialNumber"]:ToString()
