    After running the Mavericks OS X update, my Boot Camp (Windows 7 64-bit) partition is inaccessible. I don't normally keep data files on that partition, but I happen to have some there currently that are not backed up.

    Opening Disk Utility shows "BOOTCAMP" under my hard drive, but it will not mount. I have been trying to find a solution for this, but it seems the situation can vary so I would really appreciate some assistance.

    These outputs were requested in other resolutions, so I went ahead and ran each. Please let me know if the commands need to be changed for my situation.

    sudo fdisk /dev/rdisk0

    Everything looks ok to me.
    Try booting from the Windows install dvd/usb and running the automatic repair process. Once may be enough but it can need to be run up to 3 times, depending on what's wrong.
    That would be my first course of action.

    That fixed it! Thank you so much!

    Edit: Darn. Well I'm able to get to my files, and that was the most important thing.
    I can now boot into Boot Camp, but I still can't mount it from within OS X.

    Well that's half good then :)
    In Windows try scheduling a chkdsk for the next boot. Use the /F option, which will fix any errors.

    Ran the chkdsk with /f and watched it go through the process, but I still can't mount it in OS X.

    Did the chkdsk find/fix any errors? If so it should be run again until none are found.

    Try opening Disk Utility and see if the Bootcamp partition shows up in that.
    Don't do anything else in Disk Utility.
    If it mounts ok in D.U. open a Finder window and see if Bootcamp shows up there too.

    Running Disk Utility shows "BOOTCAMP" under the disk. When I select it and click "Mount", this displays:
    "Mount failed
    The disk "BOOTCAMP" could not be mounted.
    Try running First Aid on the disk and then retry mounting."

    It does not show up in Finder.

    I didn't notice that it found any errors, though there were a couple of things I didn't understand listed while it ran. It automatically booted Windows when it finished, so I couldn't get a good look at it then.

    Thanks. Other than running a second (or third) chkdsk I can't really think of anything else. My supposition is that OSX thinks the NTFS file system is unclean. Maybe there's something I've not thought of :confused:
    You don't have NTFS-3G installed do you?

    I have Tuxera NTFS installed. I downloaded the new version of that, which fixed it!

    Thanks so much for your help! I feel pretty silly forgetting about that...
