如何在c语言中读取硬盘序列号呀?
在WINDOWS底下还是DOS底下?
WINDOWS 底下我知道。
能告知吗?谢谢!
好象得调用汇编来解决……
在DOS下,去看看《计算机应用》杂志98年10期,有我的一篇文章,其中提到了这个问题,有源代码。VC++的去查微软软知识库,C++bulider的我好像收集了代码,一时想不起了。
我当时做时是根据这篇文章(来自MSDN2001),代码给了别人了,如果你要,我
尝试再找找看。
SAMPLE: SmartApp.exe Accesses SMART Stats in IDE Drives
Q208048
The information in this article applies to:
Microsoft Win32 Device Driver Kit (DDK), on platform(s):
Microsoft Windows 98
Microsoft Windows 95
SUMMARY
SmartApp.exe is a sample Win32 application that demonstrates how to access the SMART (Self Monitoring, Analysis and Reporting Technology) capabilities built into IDE disk drives.
SMART technology is used to monitor disk drive degradation, in an effort to predict future catastrophic disk failure. For more information about SMART technology, see the REFERENCES section at the end of this article.
While this article primarily centers on using SMART technology with Windows 95 and Windows 98, it also includes information about how to modify SmartApp.exe to work with Windows NT and Windows 2000.

Using the SMARTAPP sample code
SmartApp.exe is a console application that you run from a DOS command prompt. You should set up your command prompt window for 43 or 50 lines or direct the program’s output report to a file (for example, type SmartApp.exe >c:\print.txt) because SmartApp.exe can report over 25 lines of text data. Following is a sample report produced by SmartApp.exe:
SMARTVSD opened successfully
DFP_GET_VERSION returned:

The Attribute fields are defined (and refined) solely by the disk drive OEM manufacturers.
The source code (that is, Smart.h, SmartApp.h, and SmartApp.c) was compiled and tested using Visual Studio with Microsoft VC++ 5.0 as a console application.
Common Windows 95 Problems
SMARTVSD packs the structures for the DeviceIoControl in and out buffers differently from the default packing used by MSVC. The application needs to specify #pragma pack(1) to get the structure packing to match SMARTVSD.
SMARTVSD subtracts 1 from the size of the SENDCMDOUTPARAMS when it validates the size of the SENDCMDOUTPARAMS passed to it by the application. Using the above packing, the size of the structure in the SMART VSD doc would be 17 bytes long. SMARTVSD apparently compares the buffer size passed in DeviceIoControl to 16. This is presumably to discount the variable size buffer array at the end of the structure, which is defined as 1 byte long in the docs. The sizes of the SENDCMDINPARAMS and SENDCMDOUTPARAMS structures specified in the DeviceIoControl call should not include the variable size buffers located at the end of each structure.
Compiling and Using SmartApp.exe with Windows NT or Windows 2000
To compile SmartApp.exe for Windows NT or Windows 2000, comment out or delete the following line located at the beginning of SmartApp.c:
#define WINDOWS9X // Define this to compile for Windows 9x
For Windows NT and Windows 2000, the IOCTL call for SMART_GET_VERSION always returns a bIDEDeviceMap value of 1. You must select the target physical drive using the CreateFile() function. Note that for Windows 95 and Windows 98, the target physical drive is selected after inspecting bIDEDeviceMap. When the symbol WINDOWS9X is not defined (for example, when you are compiling SMARTAPP for the Windows NT or Windows 2000 environment), SMARTAPP currently only opens and reports the first physical drive, using the following:
CreateFile(“\\.\PhysicalDrive0”,GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL)
To view other drives, change the PhysicalDrive parameter to a value other than 0. Note that you can also open a drive by specifying the drive letter. For example:
CreateFile(“\\.\c:”,GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL)
SMARTVSD Troubleshooting Checklist
If opening SMARTVSD fails in Window 95 or Windows 98, one of the following might be the cause:
You are using the original version of Windows 95, which does not support SMART (the SDI_506.PDR port driver does not contain IDE PASSTHROUGH functionality).
SMARTVSD.VXD is not installed in the \windows\system\iosubsys directory.
You did not restart after installing SMARTVSD.VXD.
Your filesystem is running in Compatibility Mode (see the System Properties dialog box, click the Performance tab). This means that the protected mode IOS subsystem, containing SMARTVSD, is being bypassed.
Your system does not have any IDE drives. ESDI_506.PDR does not remain resident if there are no IDE drives.
Your IDE drives are using a third-party SCSI miniport driver instead of Microsoft’s ESDI_506 driver.
Windows 98 inadvertently omitted SMARTVSD.
If SMARTVSD opens, but you fail to get meaningful data, the IDE drive might not support SMART (especially older drives).
Common Questions
How does IDE hardware report that it supports SMART functionality?
This information is described in detail in the ATA3 or ATA4 specifications (see References at the end of this article). Specifically, Word 82 Bit 0 in the Identify Device structure indicates the drive supports SMART.
How does SMARTVSD communicate with the hard drive(s)?
SMARTVSD is an IOS layered-hierarchy VSD (Vendor Supplied Driver). At the “top” side, SMARTVSD provides the DeviceIoControl functionality to communicate with WIN32 applications. At the “bottom” side, SMARTVSD communicates with the IDE device driver (ESDI_506.PDR) using an API called IDE Passthrough.
IDE Passthrough was added to the OPK1 version (and later) of Windows 95. For additional information about this mechanism, please see the following article(s) in the Microsoft Knowledge Base:
Q196550 HOWTO: Access IDE Controller Registers Using IDE Passthrough
You can use IDE Passthrough to read or write the IDE controller’s registers, from your own IOS layer VSD (Vendor Supplied Driver).
Additional Considerations
Microsoft does not recommend replacing SMARTVSD with your own implementation. For example, if you want to make your own SCSI miniport respond to the SMART API (SMARTVSD works only with devices on the IDE bus, ignoring devices on the SCSI bus). If you do this, you will disable SMART functionality for other third-party IDE devices that use ESDI_506.
