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:
http://test.winehq.org/data/209b58c64e6181c9bf448cb4f3130d3ba705c5d2/win7_dr... (The same failure is present, when running the 64bit test)
Other machines are also affected. Example: http://test.winehq.org/data/4a685ebea343efdcb433f8d710b0c9f902e471fa/win7_ma...
You wrote the tests, which was comitted on 12. July 2012: http://source.winehq.org/git/wine.git/commitdiff/a3b5dd2dff0d04fe317f00282cc...
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: http://www.memtest86.com/downloads/memtest86-4.1.0-iso.zip (Burned on a CD)
Your broken test was not detected by winetest, but that is a different issue http://bugs.winehq.org/show_bug.cgi?id=31780
sorry for the prev. html mail
