Jun 06, 2017  The hard drive serial number or the SSD serial number is different from the volume serial number. To find the hard drive serial number or the solid state drive serial number, enter the following command in the Command Prompt. Wmic diskdrive get serialnumber. This is the serial number you can give you device’s manufacturer if you’re looking. I'm trying to read serial no of the hard disk as a unique id of the machine. IrDriveRegs: TIDERegs; // Physical drive number to send command to (0,1,2,3). I built the code segment by using Delphi XE 7 and tested it on my Lenovo. But if you prefer you can take a look on the source code and get all the.

PhysicalDrive'; begin Result:='Error'; // return empty string on error.
