>>>Hi
>>>I am developing a software in VFP for which i need the serial number of the hard disk. I don't want the Volume Number of the drive (ie c: , d: etc) as according to my information, this volume number changes whenever that volume is formatted. Can anybody help in getting the Hard Disk serial number which is manufacturer defined and which will not change.
>>> Can anyone please tell me the VFP or API function to obtain disk serial number.

On general for WMI:
"The WMI Redistributable Components version 1.0 file, which requires Windows® 2000 Service Pack 2 or later, is available to download at http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdkredist.htm.

WMI functionality introduced in the Windows 2000 SP 2 operating system is also available to earlier operating systems by downloading the Microsoft® .NET Framework SDK, and the .NET Framework Redistributable. These can be obtained at http://msdn.microsoft.com/netframework/downloads/howtoget.asp.


Run-Time Requirements

Applications that use WMI require Windows® Server 2003, Windows® XP, Windows® Millennium Edition (Me), Windows NT®, Windows® 2000, Windows® 98, or Windows® 95 operating systems. For information about which operating system is required to use a specific API element, see the Requirements section of each topic in the WMI documentation."

win32_PhysicalMedia class:
"Requirements

You might instead try with another class.
