URL: http://svn.reactos.org/svn/reactos?rev=49129&view=rev
Log:
[CLASS2]
Switch use from DISK_GEOMETRY to DISK_GEOMETRY_EX. It's needed to handle some Windows
2003's kernel routines.

[CDROM]
Reflect changes in Class2.

[DISK]
Reflect changes in Class2.
Also added support for IOCTL_DISK_GET_DRIVE_GEOMETRY_EX.
