Q: bootcamp partition no longer mountable

I was trying to get OSX to be able to read the 2 Windows partitions( named System and Data repectively). Maybe due to installations of Paragon and Tuxera, now the System partition no longer mountable in OS X,  the Data partition is still accessible.

 

I have read LonerT's instructions to other similar problems, and here are the results of those routine checks:

is it normal that fdisk has only 1 line? should have at least 4 here?  Testdisk can't print out filenames, reporting something is damaged...


Please HELP!! Many Many Thanks!!

    yes, did accordingly! but this procedure can adds folds/drives that already visible in Mac Finder. Again, System partition is not mountable in Mac to begin with... Am I mistaken?

    Did you have the System partition imported as a VM in Parallels in the past? Can you test importing disk0s4 as a VM in Parallels? It should run chkdsk or report an error.

    Yes, both NTFS partitions were automatically mounted by Parallels back in the old days. How to import disk0s4 as a VM in Parallels?

    Let us try a simpler repair first, since you have Testdisk.  In the Advanced menu, select your System NTFS partition, choose Boot, then Repair MFT.

    Just asking, you think the route of using NTFS tools (e.g. chkdsk from a windows VM) to repair NTFS partitions in OS X  is no longer possible? Remember you cautioned against using NTFS MTF tools to alter OS X's GPT and vice versa ...?

    It is valid, provided disk0s4 can be imported in the first place. If the issue is only MFT, it is faster to use Testdisk.

     

    The Parallels import is http://kb.parallels.com/en/112941 - Option 1.

     

    Try one or the other method.

    Following the instructions listed in http://kb.parallels.com/en/112941 - Option 1, at this step "From the Source drop-down list, choose your physical Boot Camp partition:"   my bootcamp partition System(disk0s4) was not listed at all. I guess VM import requires the bootcamp partition is mountable in Mac  Any other possibilities for a NTFS chkdsk on /dev/disk0s4?

     

    For the testdisk option, is there a risk of using teskdisk to repair MFT?

    steps I did so far is

     

    ./testdisk  -> append log -> choose /dev/disk0 to proceed -> to this menu

     

    Disk /dev/disk0 - 500 GB / 465 GiB (RO)

     

    Write access for this media is not available.

    TestDisk won't be able to modify it.

     

    - No partition from this disk must be mounted:

    Open the Disk Utility (In Finder -> Application -> Utility folder)

    and press Unmount button for each volume from this disk

    - This media may be physically write-protected, check the jumpers.

     

    >[ Continue ] Continue even if write access isn't available

     

     

    it says no write permission...   waiting for your confirmations to proceed

     

    here I detoured into DU and umounted Data, and remounted it then try to mount System as well, here is the System.log reports:

    It also suggests doing chkdsk on the two partitions... which chkdsk?
