    Hey guys,

    I just got my hex core Mac Pro and wanted Windows 7 on it. However, whenever I open the Mac drive, I get a "Page fault in a non page area" or something like that. I did more analysis and discovered that AppleHFS was at fault. There have been a few posts in the past on Apple's site about this, but not that much as I would have thought.

    Do you know how I can fix this? I am running Bootcamp v3.1. Why does my iMac and Macbook Pro run Windows 7 fine with v3.1?

    Not quite sure what is going on in your case but I have had Windows 7 blue screen due to issues with Mac Drive and HFS. In my case, I had a corrupted HFS volume.

    Perhaps boot into OS X and do a drive check on all your volumes in disk utility? Maybe a uninstall/reinstall of Mac Drive too...I only used it for a couple weeks and had it flake out on me a few times..... I'm now using exFAT partions...but they are not really a good solution either yet...

    I just opened my computer and installed Win7 through Bootcamp. Would the hard drive be messed up already?

    I doubt it. In that particular case it was user error. :) Where I really ran into trouble with Mac Drive was with external HFS drives. I had it happen twice where Windows 7 got in a state where I couldn't eject them properly and in both cases they got corrupted. In one case I could repair it and in one case I couldn't.

    I'm thinking your case might just be a good old Windows software conflict then. Is it a new Windows install or one you have had around for awhile? After I had the Blue Screen issue I went to uninstall Mac Drive...the uninstall failed...and Mac Drive..refused to reinstall again no matter what I tried....the only thing that saved me after about 4 hours of trying things was to remember to use a system restore point to revert back to before the uninstall. Then I repaired the disk first and I was able to uninstall properly.

    I just installed Win7 from the disc. It was running perfectly fine (although horrible looking) before I installed the Bootcamp drivers. I would leave my computer up for an hour doing Windows update and all that stuff, everything was running fine. The minute I try to access ANY file on the OS X partition, I get BSOD. I literally just opened my Mac Pro, updated OS X, and installed Win7.

    I have another hard drive I am going to try that came with my Dell replacement. I am currently wiping both hard drives and am going to do a clean install on both OS. If it happens again, what would you suggest? Deleting the .sys files helped, but I would like the ability to read HFS.

    When did you install Mac Drive? After the Boot Camp drivers or before? I would install it at the very end after you have a well functioning PC. I'd say make a system restore point before installing it, but from experience Windows 7 will do that automatically anyway.

    You might see if you still have some system restore points to restore to before you try and redo the whole thing. They work very well in my experience with them.

    I did not install the program Mac Drive. I just did Windows Update and Bootcamp drivers. That is all. I was talking about the OS X partition. I could run Win7 for hours, but the minute I open the OS X partition, I get BSOD.

    Ahh sorry guess we misunderstood each other. I do remember reading some other member's post obtaining HFS driver updates elsewhere but perhaps someone else can chime in.

    In my case, I'm not currently use "MacDrive 8" either. I can browse my HFS+ volumes fine though, although I can no longer write to them. This is the same install that did have "MacDrive 8" originally installed on it. As I wrote earlier I use exFAT partitions for sharing, the big downside seems to be that I am performing backups manually right now.

    I've never gotten Bootcamp's HFS support to work properly in Windows 7. I just disabled the HFS support entirely and I now, I longer get BSODs. To do this, you have to rename the file located here:

    Windows/system32/drivers/AppleHFS.sys (just give it a different file extension, like .bad and that should do the trick)

    Now, I just use MacDrive 8 and everything works perfectly. You also get write support with MacDrive 8, which is absent from the "free" HFS support you get with the Bootcamp drivers. The only downside is that it's not free (it's $50).

    I've had a similar problem once with accessing the hard drive (any in fact, not not only the HFS+ ones, also the NTFS Windows boot drive) from Windows 7.

    I always got a blue screen when accessing a hard drive. After re-installing Win 7 everything was fine. No problems till now.

    Okay it seems that if I do some deep analysis on HFS, like virus scanning or hard drive benchmarks, this happens. If I simply open the partition in Windows Explorer, it seems to be working fine. Does that give you any other ideas?

    There's no fix for this that I know of. I renamed AppleHFS to AppleHFS_Disabled and AppleMNT to AppleMNT_Disabled, rebooted, and the blue screens disappeared. It has nothing to do with Windows 7 - I never had a blue screen with Windows 7 until I installed these faulty drivers with Boot Camp. I finally settled on running Windows 7 under Parallels, which gave me the real-time file transfer I needed between OS X and Windows 7 without using Apple's drivers. Another option is Paragon HFS for Windows, which is included with Paragon NTFS for Mac.
