Macintosh HD partition is not visible in Windows

Hello

I've a MacBook Pro mid 2012.

A week ago I had a problem with OSX 10.9 and the Apple Premium Reseller fixed it with a clean instal of OSX. I've set everything back with my Time-machine backup. Because it was a software problem, my windows partition wasn't damaged. In Finder I can see the BootCamp-partition and of course my Macintosh HD-partition. But when boot with windows I can only see the Windows BootCamp-partition but not he Macintosh HD-partition. And that's my problem. I want to see the Macintosh HD-partition in windows. Before the clean install I could see the Macintosh HD-partition and now I want it back because I need it.

I've downloaded the newest BootCamp software (Boot Camp Support Software 5.1.5621) and installed it. Because the HFS+ driver is included in the BootCamp software you should think it solved the problem but it doesn't. I've read many communities and they told about only to reinstal the HFS+ driver which was exluded from the BootCamp software but this also didn't work.

I also tried to give the Macintosh HD-partition a 'disc-letter' because maybe that should be the reason why I can't see the partition but I can't give the partition a letter. I did it this way: Run => type: diskmgmt.msc. But it's impossible to give it a letter. (See additional photo at the bottom) I only can delete the partition when I right-click on it. (Is it normal that my disc have so much partitions which I don't know?)

Can someone solve my problem please?

Thank you very much for helping me out!

So the clean re-install of Mac isn't done correctly? Because it isn't HFS my partition?

Do you use FileVault? Please post the output of diskutil list.

Your OSX re-installation may be incorrect or file-vault encryption is in use which will render the OSX volume unreadable on the Windows side.

There is a method to revert core storage (diskutil cs revert), but that requires that the original volume was created using diskutil cs convert.

Please see man diskutil in OSX Terminal.

Yes I use FileVault. Is that the problem. But I think I used it also before the clean re-install and then Windows BootCamp worked fine.

NAME

diskutil -- modify, verify and repair local disks

SYNOPSIS

diskutil [quiet] verb [options]

DESCRIPTION

diskutil manipulates the structure of local disks. It provides informa-

tion about, and allows the administration of, the partitioning schemes,

layouts, and formats of disks. This includes hard disks, solid state

disks, optical discs, CoreStorage volumes, and AppleRAID sets. It gener-

ally manipulates whole volumes instead of individual files and directo-

ries.

VERBS

Each verb is listed with its description and individual arguments.

list [-plist] [device]

List disks. If no argument is given, then all disks and all

of their partitions are listed.

1. As a test, disable FileVault - OS X: About FileVault 2

2. Verify that your disk is no longer a CoreStorage volume using diskutil list and gpt command. Please verify the GPT #2 has the GUID as I mentioned earlier.

3. Switch to Windows and check if you have access to HFS volume.

4. For your TB volume, please test similarly.

5. There are two versions of File Vault (1 and 2) and they behave differently. See this reference for more information on differences - http://en.wikipedia.org/wiki/FileVault

Please post back your test results.

I everything fine now with this? Is there nothing that I have to set back like the things I've changed with these commands:

sudo fdisk -e /dev/disk0

setpid 2

Or is this not necessary?

Further I still have the problem that I can't get access to my TB drive in Windows. Which similar tests I've to do for this drive? Because there is no FileVault on my TB drive, it was only on my Macintosh HD.

Thanks for helping me out!

1. The fdisk commands you executed fixed the MBR side. You do not need to undo it. You can verify the setting of the MBR by sudo fdisk /dev/disk0.

2. Please execute diskutil cs list again with the TB drive connected. Did you disable FileVault when the TB drive was connected? /dev/disk2 still shows CoreStorage which Windows will not be able to access.

3. Do you have two physical 1 Terabyte drives?

4. Was /dev/disk3 (Thunderbolt HD) ever configured as CoreStorage or FileVault?

5. The GPT command is executed as sudo gpt -vv -r show /dev/disk[n] where, n=0,1,2,3. Please replace '[n]' with appropriate digits like 0,1,2,3.

OSX will re-number drives as they are connected/disconnected. The 15.8Gb looks like a USB flash drive.

I didn't disable FileVault while my TB drive was connected. Is this wrong? But in system preference => Securit and privacy => FileVault there was written that only on Macintosh HD was FileVault.

If you say '/dev/disk2 still shows CoreStorage' is that for the Macintosh HD or the Thunderbolt drive? Because my internal drive is 500GB ( 450GB for Macintosh HD and 50GB for BootCamp). This is the only internal drive in my MacBook Pro.

I've only one TB drive with only one physical drive in it with a storagege of one Terabyte.

4. I never configured Thundebolt HD. I bought it and I used it. So I didn't nothing with it.

Maybe you need this to know: I use this Thunderbolt HD for TimeMachine...

When I look in Finder cmd+i I can see that my Thundebolt Drive is encoded:

That explains it. It looks like your TM backups are encrypted. Please see this - OS X Mavericks: About the Time Machine backup password.

It can be seen here as well as you can see the different PartitionType GUIDs (different from /dev/disk1 GPT #2).

409640 1952853344 2 GPT part - 53746F72-6167-11AA-AA11-00306543ECAC

As a test, can you remove the encryption on the Thunderbolt HD and test from the Windows side.

Before you switch to Windows, run diskutil cs list after removing encryption and you should not see any CoreStorage volumes.

diskutil list should just see a plain /dev/disk2 with your FREECOM HDD as an HFS+ disk. Test from Windows and post your results.

Till Apple provides a CoreStorage driver for Windows, any encrypted or FileVault drives will not be readable.

With your Thunderbolt HD connected to the Mac, go into System Preferences -> Time Machine. Click on the Thunderbolt HD, and if the "Encrypt backup disk" is checked, uncheck it.

I will check on my TM backup disk once it is connected.

Loner T it looks fine but at the start up where I can choose my drive I see now 2 times my Thunderbolt HD (=Freecom HDD):

Before I removed the encryption on theThunderbolt HD I saw only one 'Freecom HDD at start up'.

Also in Windows I see it two times:

How can I make one drive of my Thunderbolt HD? Or what's the problem with it?

In windows explorer I see just my Thunderbolt HD:

Notice that you a 'Boot OS X'. Do you have an Operating system installed on your Thunderbolt HD (the EFI being present on it also indicates that it had an OS at some point in time)? This seems the only logical reason why it would show up more than once.

If the TB HD was only used for TM backups, it should not have either partition. Also, if the CoreStorage volume had used both the drives at some point then it would have the EFI and Boot OS X partitions, but TM disks have only a Data (Sharepoint) partition.

Can you execute sudo fdisk /dev/disk2 and sudo gpt -vv -r show /dev/disk2, and post the output?

Macintosh HD partition is not visible in Windows
