CD/DVD-ROM Block Driver Test Cases (Windows CE 5.0)
The following table shows the test cases for the CD/DVD-ROM Block Driver Test.
| Test case | Description |
|---|---|
| 6001: Device ready check | Tests the functionality of the IOCTL_CDROM_TEST_UNIT_READY IOCTL.
This test case fails if the DeviceIoControl function call returns FALSE. Failure occurs if the driver does not properly support the IOCTL_CDROM_TEST_UNIT_READY control code. Failure also occurs when the DeviceIoControl function call does not set the bUnitReady flag to TRUE in the CDROM_TESTUNITREADY structure. This test case fails if there is no media in the drive because the function call sets the flag to TRUE only when there is media present. |
| 6002: Query CD-ROM Disk information | Tests the functionality of the IOCTL_CDROM_DISC_INFO IOCTL.
This test case fails if the DeviceIoControl function call returns FALSE. Failure occurs if there is no CD or DVD in the drive. |
| 6003: Perform 1 Sector Reads | Reads each sector from the media one sector at a time and compares the contents of each sector to the contents of the image file in the release directory. For information about specifying the location of the image file by using the /image command-line parameter, see Modifying the CD/DVD-ROM Block Driver Test.
This test case fails if it is unable to read any sector from the media in the drive. The test case also fails when the drive reads fewer bytes than were requested, and when there is a discrepancy between the data on the media and the data in the image file. Be sure that there is media in the drive and that the specified image file in the release directory on the development workstation matches the contents of the media. |
| 6004: Perform 32 Sector Reads | Reads each sector from the media 32 sectors at a time and compares the contents of the sectors to the contents of the image file in the release directory. For information about specifying the location of the image file by using the /image command-line parameter, see Modifying the CD/DVD-ROM Block Driver Test.
This test case fails when it is unable to read any sector from the media in the drive. The test case also fails when the drive reads fewer bytes than were requested, and when there is a discrepancy between the data on the media and the data in the image file. Be sure that there is media in the drive and that the specified image file in the release directory on the development workstation matches the contents of the media. |
| 6005: Perform 128 Sector Reads | Reads each sector from the media 128 sectors at a time and compares the contents of the sectors to the contents of the image file in the release directory. For information about specifying the location of the image file by using the /image command-line parameter, see Modifying the CD/DVD-ROM Block Driver Test.
This test case fails when it is unable to read any sector from the media in the drive. The test case also fails when the drive reads fewer bytes than were requested and when there is a discrepancy between the data on the media and the data in the image file. Be sure that there is media in the drive and that the specified image file in the release directory on the development workstation matches the contents of the media. |
| 6006: Test increasing read request sizes | Performs multiple-sector reads. The number of sectors included in each read starts at one and increases with each read until the number reaches the maximum number of sectors that can be read, as specified by the /maxsectors command-line parameter. The data that is read is compared to the data in the specified image file. For information about specifying the location of the image file by using the /image command-line parameter, see Modifying the CD/DVD-ROM Block Driver Test.
This test case fails if the test is unable to allocate a large enough buffer to store the data being read. Such a failure does not indicate a problem and can be solved by setting a smaller maximum number of sectors using the |
| 6007: Perform Multi-SG Reads | Tests the ability of the block driver to support reads with multiple scatter-gather (SG) buffers. This test reads data from the disk using a single SG buffer, and then reads the same data in multiple SG buffers. The test verifies that the data read is the same in both cases.
This test case fails if the device does not support multiple SG buffer reads. |
| 6008: Test various buffer allocation types | Tests the ability of the drive to read data into the following types of buffers:
This test case might fail if the drive does not appropriately support reading into an unaligned buffer. |
| 6009: Read CD-ROM table of contents | Verifies that the driver supports the IOCTL_CDROM_READ_TOC IOCTL. If the values in the table of contents seem incorrect, the test case generates a warning, but does not fail. The test writes table of contents information to the test log. Microsoft recommends that you manually verify the log.
This test case might fail if the driver does not support the IOCTL_CDROM_READ_TOC IOCTL or if there is no media in the drive. |
| 6011: Issue an ATAPI device info inquiry | Tests the functionality of the IOCTL_CDROM_ISSUE_INQUIRY IOCTL, passing an INQUIRY_DATA structure as the output parameter.
This test case fails if the DeviceIoControl function call returns FALSE for the IOCTL_CDROM_ISSUE_INQUIRY IOCTL. |
| 6012: Verify media eject and load functionality | Tests the functionality of the IOCTL_CDROM_LOAD_MEDIA and IOCTL_CDROM_UNLOAD MEDIA IOCTLs. The test case first attempts to eject the media, and then follows with an IOCTL_CDROM_TEST_UNIT_READY IOCTL to verify that the media is not present. The test case then loads the media and follows with a second IOCTL_CDROM_TEST_UNIT_READY IOCTL to verify that the media is loaded.
This test case fails if any of the DeviceIoControl function calls return FALSE, if the unit appears to be ready after ejecting the media, or if the unit is not ready after reloading the media. |
| 6101: Make image of CD media | Creates an image of the media that is loaded in the drive and saves the file containing the image in the release directory on the development workstation. For information about specifying the location of the image file by using the /image command-line parameter, see Modifying the CD/DVD-ROM Block Driver Test.
This test executes until it fails or until 328220 sectors are read. If the |
