Greetings,

 

I have recently installed Boot Camp and Windows 7 on my new (2012) iMac.  So far, so good - no major problems in getting Windows up and running.  However, unlike my older Boot Camp installation, this one does not seem to mount, even read-only, any of my Mac volumes.  Neither the internal fusion (1 TB) drive or an external 2 TB USB3 drive show up.

 

Also, possibly related, is that the drives show up in the Boot Camp control panel named "disk 1" and "disk 2" although it does seem to know that OS X is installed on them.  I'm guessing that one of those is the Recovery partition.

 

Did Apple remove support for mounting HFS drives in Windows with newer versions of Boot Camp?

 

To be honest, I actually prefer the drives to not show up at all but I would like the correct volume names to show up in the control panel.

 

Thanks in advance.

    You have to install the Apple Support Software to get read access to HFS volumes.

    I did install the Apple Support Software.  Hmmm.  Do you know if the Apple Software Update utility checks for old or missing Apple drivers as well as applications, etc.?  Or perhaps there is another utility hidden somewhere?

     

    For what it's worth, the "About Boot Camp" window says it's Version 4.1 Build 4586 (this is on Windows).  Should it say 5.x instead?

    Then the problem is likely due to the fact that you have a Fusion Drive. I don't believe Apple has updated its Windows software to properly support it.

    Reboot to OSX and check the version number of Boot Camp Assistant, if you have Mountain Lion it should be 5.x

     

    Always post your OSX version when asking for assistance.

    I did some more testing and I was able to get an external HFS volume to mount on Windows.  I recall now having a similar problem with my old Boot Camp system.  An external drive would not mount when I started Windows but instead I got a "USB device unrecognized" message.  But I was then able to get it to mount by unplugging the drive's USB cable and re-inserting it.  (The drive was an old WD MyBook which doesn't have a physical on/off switch.)  Anyway, I turned off my external USB3 drive and turned it back on and it mounted just fine.

     

    So I think you are probably correct - it's the fusion drive that's not supported (yet?), and not a problem with HFS.

    Csound1,

     

    I think my original issue (Windows HFS support) is solved, but I will check the Boot Camp version.  The OS version is Mountain Lion, presumably 10.8.2, that came with my late 2012 iMac.  I should have specified that.

     

    Should I expect the version displayed in Windows to be the same as that on the Mac?  The support software CD used was created from within the (new) Boot Camp utility and not downloaded directly.

    No, it will differ. Mountain Lion comes with Boot Camp 5. Creating the disc in Boot Camp rather than a direct download is the correct method.

    How did you fix this issue? I am running Windows 7 Professional alongside 10.9 on a MacBook Air. For some reason Windows is not seeing the HFS+ Macintosh HD partition.

     

    I was wondering if Apple stopped including the Windows driver for HFS, but it seems you got it working under 10.8.

     

    I can say that I was able to get this working in the past on my Late 2007 Black MacBook
