Introduction

Making sure your software is used by legal buyers is a concern for programmers around the world. My professor once said that we shouldn’t give 100% of our code to the users because there are people out there that are smart enough to decompile our programs and find the various verification algorithms used. He suggested that we give users 99% of our software, but keep the remaining 1% to ourselves. This 1% is the verification algorithm to confirm only valid users can use the program; this is commonly known as “activation.”

Activation is good, but it means our software users will need to have Internet access and that means small programmers like us have to set up a server that can validate users. Of course, only big companies with big clients can afford to do this. For the rest of us, we have to think of other ways.

Now there's a problem: the hard drive model is found in the Win32DiskDrive class and the serial number is found in the Win32PhysicalMedia class. Thus, we need to query twice and integrate the information into our HardDrive class. Let's first create an ArrayList to store our HardDrive objects: ArrayList hdCollection = new ArrayList.

One method programmers have used since the DOS era was to bind their software to the Hard Drive Volume Serial Number. This is not a good choice, as later we all find out that every time we format the same hard drive, a new Volume Serial Number is generated.

And it was returning 000020 and not 000026 which is correct serial number of drive e.g. Last digit wrong. If your VB application is returnng incorrect data for the serial number of the device then you need to show the code that you are using, not just fragments. In the displayed output, find the 8-digit number listed as the Volume Serial Number for C drive. Make sure that the message is Volume in drive C is OS. The case of the letters is not important and no dash is included. In this example, you would enter 12abcd34. Does not work if your hard disk has died completely and you're looking for the serial number of the faulty unit. Use @Johann's method instead. – niieani Mar 30 '16 at 16:40 I had to install the (apt-ly named) hdparm package on ARM (Raspbian on Raspberry Pi).

Option Three: To Find Serial Number of Hard Drives in PowerShell.

How To Find Hard Drive Serial Number

Background

A better solution is to get the Hard Drive Serial Number given by the Manufacturer. This value won't change even if you format your Hard Drive. Of course, if people buy new hard drive, we have a problem. But at least we keep the regular hard-drive formatters happy!

The Code

First, let's create a class to store information about a hard drive:

Next, add a reference to your project. Scroll down to System.Management under ComponentName. This reference is not provided by default, so you need to add it.

Add a 'using System.Management;' at the top of your source code. System.Management allows us to access WMI objects. Put simply, WMI contains a lot information about your hardware.

Now there's a problem: the hard drive model is found in the Win32_DiskDrive class and the serial number is found in the Win32_PhysicalMedia class. Thus, we need to query twice and integrate the information into our HardDrive class.

Let's first create an ArrayList to store our HardDrive objects: ArrayList hdCollection = new ArrayList();. Next, we query the Win32_DiskDrive class:

Now we need to extract the serial number from the Win32_PhysicalMedia class:

Luckily, the WMI objects from Win32_DiskDrive are in the same order as from Win32_PhysicalMedia, so the simple code above works. Otherwise, we will have to match them using their unique DeviceID. Start a thread in this article if you think Win32_DiskDrive objects are not the same order as Win32_PhysicalMedia objects returned.

We are done! Now we display our hard drive's information:

Conclusion

Get Hard Drive Serial Number

If a user has more than one hard drive, I suggest you display the available hard drives to the user. Ask him which hard drive he's not planning to upgrade soon, then use that hard drive serial number to generate a license key. This will prevent your user from nagging for a new license key in short time.

If your user finally decides to upgrade hard drive, you may give this article's demo application to the user and ask him what the serial number is. Alternatively, you can create a much more user-friendly GUI one. :)
