Bug ID: 36492
           Summary: mountmgr:harddisk_ioctl Unsupported
           Product: Wine
           Version: 1.7.19
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mountmgr.sys
          Assignee: [e-mail]
          Reporter: [e-mail]

It's me again. 
I upgraded to the latest wine and again tried to install and run Dragon
Naturally Speaking into a 64-bit wineprefix. 
Again it seemed to install well, but crashed immediately when I tried to run
it. 
I did both the run and install with winedbg set to "all," and I think the
results may point to this in the runtime log:

----snip----
fixme:mountmgr:harddisk_ioctl returning zero-filled buffer for
IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS
fixme:mountmgr:harddisk_ioctl Unsupported ioctl 74080 (device=7 access=1
func=20 method=0)
----snip----

The runtime log is very short. I have attached both logs.
