Formatting partitions is a common operation in our opinion. You can click twice to solve the problem, but it is not easy to implement it in the program. Some people may say that it is not good to directly call the format command, but the system command contains the problem described in Section 1 http://cutebunny.blog.51cto.com/301216/624027.

I have found three methods: 1. Windows API shformatdrive. The function prototype is DWORD shformatdrive (hwnd, uint drive, uint fmtid, uint options). The drive parameter is the partition to be formatted and starts counting from 0. 0 represents a:, 2 represents C:, and so on. For other parameters, see msdn. When you call this function, a dialog box that we are very familiar with is displayed. You can right-click it to format it.

The call method is simple:

Shformatdrive (0, 8, shfmt_id_default, shfmt_opt_full );

Unfortunately, this API cannot automatically start formatting. In any case, you must manually click Start ". Depressed, some people suggest you set up a timer and simulate enter again. After formatting, enter again. It works in principle, but it seems to be a bit nondescribable. 2. Using the undisclosed formatex function in fmifs. dll, a big guy named Mark russinovich wrote the specific code. I haven't taken the time to tune it for your reference. For more information about the code, see the attachment. Someone seems to have succeeded, please refer to the http://forum.sysinternals.com/creating-partitions-on-xp_topic3029.html 3. Format command this is no way, the Code is as follows, very simple, not much explanation. /*************************************** **************************************** Function: * input: disk, disk name * output: N/A * return: succeed, 0 * fail, 1 *************************************** ***************************************/ DWORD formatvolume (char letter) {DWORD ret; char cmd [64]; sprintf (CMD, "format % C:/Fs: NTFS/Q/Y", letter); ret = (DWORD) system (CMD); return ret ;} SummaryThe discussion on disk operation programming in Windows has come to an end. Finally, let's summarize all the examples we have listed above. DWORD getallpresentdisks (DWORD ** disks); // all physical disk numbers in the query system DWORD getsystemdiskphysicalnumber (void ); // obtain the physical disk number DWORD getphysicaldrivefrompartitionletter (char letter) of the operating system. // query the physical disk number DWORD getdrivegeometry (const char * disk, disk_geometry * PDG) based on the Logical Partition Number ); // query the disk physical information DWORD getdiskdrivelayout (const char * disk, drive_layout_information_ex * drivelayout); // query the disk partition information DWORD destroydisk (DWORD disk); // Delete the disk partition table DWORD cr Eatedisk (DWORD disk, word partnum); // initialize the disk and create a partition DWORD getpartitionletterfromphysicaldrive (DWORD pdrivenumber, char ** letters ); // query all the DWORD formatvolume (char letter) partitions on a physical disk, be careful when debugging. Of course, do not use it to do bad things.
