IOCTL_DVD_READ_STRUCTURE (DvdPhysicalDescriptor) test failure [text only]

[Detlef Riekenberg]

Hi Alexandre.

I have a test failure on my win7 Machine, while a valid cd was in the dvd drive.
volume.c:785: Test failed: IOCTL_DVD_READ_STRUCTURE (DvdPhysicalDescriptor) failed, last error = 1785

Example result:

(The same failure is present, when running the 64bit test)

Other machines are also affected.

You wrote the tests, which was comitted on 12. July 2012:

What media did you use, to test your code?
Data-DVD, Video-DVD, Empty DVD, Data-CD, Video-CD, Audio-CD, Empty CD, No Disc in Drive

What results did you get on Windows and Unix?

On Linux, mounting the example CD works perfect, but your test fails:
volume.c:785: Test failed: IOCTL_DVD_READ_STRUCTURE (DvdPhysicalDescriptor) failed, last error = 87

Your test only read the DVD descriptor.

To fix your test, I suggest, that you add a trace to dump the
*_READ_STRUCTURE IoControl result and add similar tests
for the other media formats.


I also tested with a different Data-CD and got the same failure on linux (last error = 87).
You can check the image yourself:

(Burned on a CD)

Your broken test was not detected by winetest, but that is a different issue
