I wanted to get the serial number assigned by Hard disk manufacturer. The serial number is usually printed in the hard disk. Normally to get the serial number, I have to take out the hard disk. Is it possible to know the hard drive serial number from command prompt or in other way.

BDriveNumber: BYTE; bReserved: Array[0.2] of Byte; dwReserved: Array[0.3] of DWORD; bBuffer: Array[0.0] of Byte; // Input buffer.

BDriverError: Byte; // Contents of IDE Error register. Only valid when bDriverError is SMART_IDE_ERROR.

DriverStatus: TDriverStatus; // Buffer of arbitrary length in which to store the data read from the drive.

Number

It’s surprisingly a non-trivial issue to retrieve the manufacturer’s information from a hard drive. Some people recommend using the API function. The problem is that this is not the serial number printed on the hard drive and assigned by the manufacturer, but is (according to the MSDN documentation): This function returns the volume serial number that the operating system assigns when a hard disk is formatted. To programmatically obtain the hard disk’s serial number that the manufacturer assigns, use the Windows Management Instrumentation (WMI) property SerialNumber.

Notice also that it recommends to use the WMI Win32_Physical Media property “SerialNumber” to obtain the manufacturer’s serial. Interestingly enough,. The reason is that this property is optionally defined by the manufacturer and must be supplied by the hard disk driver. So if we can’t use GetVolumeInformation() and we can’t rely on WMI 100% of the time, what can we do? Well, it involves querying several sources of information on a system directly. It also means we have to care if the drive is SATA, IDE, etc.

Well, the smart folks at, wore an open-source application called DiskId32: DiskId32 is a Win32 console utility for reading the manufacturer’s information from your hard drives. Lykke li wounded rhymes mediafire. It runs under Windows 9X, Win NT, Win 2K and Win XP (Pro/Home).

DiskId32 does not run on plain old DOS and I highly doubt that it works on Windows 3.x. It does NOT require administrator rights for Win NT/2K. I have seen this application recommended on many occasions, although there are that use similar methods. There is an open-source application called DiskID32 that is written in C++. Looking at the source code, it takes many scenarios in mind when attempting to retrieve disk information.
