Remarks

The following steps describe how to format a drive:

  1. Open a handle to the volume.
    The name of the volume to open has the format \FolderName\Vol:, where FolderName is the FAT file system name for the root directory of the mounted volume.

  2. Call the DeviceIoControl function with the volume handle and this I/O control.
    The following code example shows this procedure.

    hVolume = CreateFile(TEXT("\Storage Card\Vol:"), GENERIC_READ|GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);
DeviceIoControl(hVolume, IOCTL_DISK_FORMAT_VOLUME, NULL, 0, NULL, 0, NULL, NULL);
