I need to show the printed serial number of an external usb hard drive using c# .
I have found many sources in "github" but the returned serial number is not correct. the only program that gave me the correct serial number is "CrystalDiskInfo" which is open source but written in c ++ which I do not understand.

Here is an example with "CrystalDiskInfo" with the correct result:

Thanks for help

Use WMI. http://csharphelper.com/blog/2017/10/get-hard-drive-serial-number-c/

Thanks for the link , I have already used several sources but the serial number is still wrong and do not forget that it is an external Usb hard drive what can make things more complicated.

This is an image as a proof:

You never mentioned that.  USB enclosures are tricky, some of them they report their own serial numbers and some - serial numbers of the actual hard disk.
My WD Book enclosure works fine with the code I suggested earlier.

 

Try running in command prompt:

wmic diskdrive get Name,Model,SerialNumber,Size,Status

If you don't see the correct information there, then C# application will not be able to get it without writing a lot of specific code (like Crystal Disk Info).

No luck, the serial number is still incorrect with the "wmic" command.  I think things are more complicated than I thought. So, I will try to use a third party tool to get the correct result.

Thank you anyway

Probably you don't have admin rights.

Try this : GetVolumeInformationA  >>  https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-getvolumeinformationa

Thanks for your help.

ManagementObjectSearcher can't get the correct searial number,sometime.

To obtain the correct disk name and serial number, the best approach is to use CrystalDiskInfo(https://github.com/hiyohiyo/CrystalDiskInfo) . However, CrystalDiskInfois a Windows software written in C++. As a result, it cannot be directly used in one's own project. Therefore, I wrapped CrystalDiskInfo into a DLL. Now, other languages or Windows applications can also accurately distinguish the disk serial number with the help of CrystalDiskInfo. I have open-sourced this project on GitHub. If you are interested in it, you can check it out and use it.
