Q: all OSX drives got converted to windows drives, HELP!

Mac Pro 4,1 (flashed to 5,1)

3.33ghz hex-core Xeon x 2

48 GB RAM

Running OSX 10.10.5 and Windows 7 SP1 via Bootcamp

5 Hard Drives total; partition layout:

(all disk numbers are windows based using windows' "disk management" program (can't remember their OSX designations)

 

disk 0 (120GB SSD):           BOOTCAMP drive, win 7 SP1 installed (NTFS)

disk 1 (640GB HDD):           DEDICATED OSX BACKUP (10.10.5)...I clone my main OSX drive to this drive daily (HFS)

disk 2 (2TB HDD):                Windows Files and Archives (NTFS)

disk 3 (2TB HDD):                OSX Files and Backups organized into 4 partitions (all partitions are HFS):

                                                  partition 1: OSX BACKUP...I also clone my main OSX drive to this drive daily (all bootable clones done with Cronosync)

                                                  partition 2: PROJECT BACKUP (backups of current and past projects)

                                                  partition 3: OTHER BACKUP: this holds my time machine backups and other miscellaneous backups

                                                  partition 4: SAMPLE DRIVE: I do music production, so I keep my sample libraries here.

disk 4 (256GB PCIe SSD):  Two Partitions:

                                                  partition 1: MAIN OSX DRIVE: Running 10.10.5, my master drive (HFS)

                                                  partition 2: WINDOWS FAST STORAGE: used for installing windows programs that benefit greatly from faster speeds.(NTFS)

 

Will outline how I got to this point step by step :-\

 

1) Accessing Mac partitions over while in windows (just opening certain folders on certain drives) would cause BSOD. Based on internet suggestions, assumed the AppleHFS driver in windows was faulty so decided to install MacDrive 8...big mistake!

 

2) after installing MacDrive, I disabled the AppleHFS.sys file in windows/system32/drivers by renaming it to extension .bad

 

3) Was working on some stuff in windows for a few days so I stayed on that side for awhile. Was trying to copy a large folder (30 GB)  to my Bootcamp drive, but windows gave an error that it was out of memory. This would be followed by the Bootcamp drive locking up completely so I'd have to hard shutdown. Did this a few times. Eventually got the issue corrected by Over Provisioning the drive (forgot to do that before installation of Windows).

 

4) A few times whle accessing the recycle bin, MacDrive would warn me that my project backup partition was damaged or corrupted and asked if I wanted to mount it. Decided around this point to switch back to OSX using the Bootcamp control panel, lo and behold all of my OSX partitions had been turned into windows drives!

 

4) Panicked, I shutdown and restarted, holding the option key. The only drives that showed up were Windows (disk 0) and Recovery 10.10.5...all OSX drives are not visible in EFI as mac drives.

 

5) I uninstalled MacDrive and reverted the old AppleHFS.sys file to its normal state. Drives are all accessible within windows (and all files are seemingly intact, didn't go exploring too hard for fear of more BSOD's). No change in boot camp control panel or at system boot. Mac drives still shown as windows drives.

 

6) Tried booting into the internal Recovery...didn't work. Would cause an endless loop of showing the apple and the loading bar would get to about halfway before it reboots and tries again.

 

7) Tried Resetting the PRAM and SMC...PRAM reset didn't go as advertised...it would chime once, get grey screen for 1 second and then about another 20 seconds til another chime (I"m holding cmd+opt+P+R the whole time), so I don't think it's the "2 chimes" for PRAM reset.

 

8) Created a bootable yosemite recovery drive (twice!), but would only load halfway followed by a restart. endless loop again.

 

9) Internet recovery doesn't work...all methods of recovery result in endles loop of restarts.

 

10) downloaded gdisk for windows as suggested here: Mac drive no longer showing up as boot option? but not sure how to use it to repair the drives.

 

 

Any help in repairing at least one drive enough for me to get back into OSX and/or recovery would be greatly appreciated!

Mac Pro, OS X Yosemite (10.10.5)

    Yes, the recovery that I used earlier today was on my external hard drive...that one worked as long as I switched video cards to the old one...

     

    This one on the internal drive is probably not working because of the video card as well (it's doing the same thing as before: restarting the machine before fully booting up). I wish there was a way to have any recovery work with my new video card.

     

    Regardless, I will test the internal recovery tomorrow with the old video card...will let you know tomorrow.

    I noticed two things since fixing the drives:

     

    1) My bootcamp drive is not visible in OSX and can't be mounted. I can still boot into it using the option key during startup, but I can't set it as the default startup disk.

     

    2) In Windows, I can see all the drives and partitions, but there's a 2nd windows partition there without a meaningful name...I'm wondering if that partition is the recovery partition that (maybe) hasn't been converted to HFS+. I remember in gdisk, it said the OSX recovery partition was AB00...is that normal?

    Since you have multiple copies of OS X, we need to figure out which OS X and which Windows partition. If you to post the two specific diskNSn numbers, it would help.

     

    What is the size of that partition? A recovery should be about 620MB. Can you run the same DD command on that specific disk which you suspect to be the Recovery disk?

    There's only one OSX recovery on this machine and it's disk4s3. That was my original OSX drive, all other OSX copies are just clones of the OSX partition; the recovery partition was never cloned.


    The 2nd recovery you are thinking of is from the external drive I did a clean install of 10.10.5 onto. That drive is not a regular part of my machine.

    Disk2 should be either

     

    a. a MBR disk, or,

    b. a GPT disk with a Hybrid MBR with a NTFS partition.

     

    Can you post the GPT for disk2?

    I should tell you that this installation of windows gave me lots of problems at first...transferring big files would cause the drive to freeze, and I had a very hard time resizing the drive for Over-Partitioning (it's a SSD).

    It says that there is a GPT with hybrid MBR, has no other entries. If this is a clone of another disk on your Mac, there seems to a UUID conflict.

     

    If you go to 'r'(recovery) menu and enter 'o'(show hybrid MBR), what output do you get?

    I'm trying to remember, but I think I restored an image backup (HDM Backup is the file type) of my previous bootcamp using Paragon VMDK Mounter (I made the image with Paragon as well)...was trying to find a way to backup my bootcamp within OSX...might not have been the best solution?

    From a Terminal, can you post the output of the following command....

     

    sudo gpt -vv -r show /dev/disk2

     

    If this is a Paragon clone, without a GPT and just an MBR, it broke a few rules.
