#86498 — Can't have both encrypted Mac's HFS+ & MS W7 EE SP1's BitLocker NTFS?

Hi.

I'm having problems with my 2 MS partitions in my external USB 2 TB WD 
Green HDD. I wanted to have 2 encrypted partitions (W7 EE SP1's 
BitLocker NTFS and HFS[Time Machine and manual Mac files]) and an 
unencrypted FAT (tried both FAT32 and exFAT). I had no problems 
(mak/creat)ing them. 

The problem is that Mac OS X v10.10.5 (Yosemite) thinks I have 2 FAT 
drives (only 1 should exist while other is NTFS (assuming cannot be read 
due to its BitLocker encryption which is fine to me)). If I connect it 
to a W7 laptop/notebook, then only FAT can be seen.

I tried reformatting the encrypted BitLocker NTFS to unencrypted FAT in 
Mac OS X's Disk Utility which can be seen in Mac, but W7 does't see it. 
I tried letting W7's Disk Management make this unallocated partition to 
a new simple volume (NTFS or exFAT -- tried both), but it said "The 
operation you selected will convert the selected basic disk(s) to 
dynamic disk(s). If you convert the disk(s) to dynamic, you will not be 
able to stat installed operating systems from any volume on the disk(s) 
(except the current boot volume). Are you sure you want to continue?" I 
tried Yes and its Virtual Disk Manager said "The operation is not 
supported by the object." :(

I tried deleting all partitions and told Mac OS X's Disk Utility to 
recreate the 3 partitions (unencrypted HFS+ & 2 MS FAT partitions) from 
scratch. Everything was fine when I checked between machines. I told W7 
to format a FAT partition into NTFS with BitLocker encryption. After it 
was done, I rechecked with Mac OS X. Partitions were fine (yes, I know 
Mac can't read BitLocker encryptions so that partition stays hidden). I 
told Mac OS X to do a very long encrypted Time Machine backup and 
manually copy some files into this encrypted HFS+ partition for hours. 
After that, I went back to W7 and it can't see my BitLocker partition 
(unallocated)!

http://i.imgur.com/tJ5wWz6.gif and http://i.imgur.com/KBwAEct.gif and 
for my 2 screen (shot/capture)s from both machine with the same external 
USB HDD connected.

What's going on? Does having 2 different encrypted partitions not work 
with each other? Or am I doing something wrong? :(

Thank you in advance. :)

Why bother with that rather than simply running Windows in a virtual
machine with an associated virtual drive in the OS X file system?

Because I want to share the drive between multiple physical machines.

Have fun with that. A virtual machine is far better for my needs.

You should leave attribution in posts.

When you reply to a post, whatever content you leave from previous 
posters should be identifiable to who wrote it.  You tend to cut out who 
wrote what making it a pain in some cases to go read more of what that 
poster wrote.

Your prior reply to Paul, for example quotes what he said - but not who 
said it.

Ah OK. Sorry. I was trying to clean thing up. Don't you have threading 
to show them?

Easier to just read the name in context.

That's not the point. What you are doing is considered bad etiquette.

The disk in question is GPT.

It's possible that an unallocated section of the disk,
shows up as a "partition" under GPT. And that's where
two FAT come from.

I would try to apply labels to the partitions, so you
have more landmarks when you're lost. For example,
my C: partition might be "Win7" or "Win10" depending
on what I was using. And since not all display routines
actually have the ability to display the label, I also
place a zero-sized file "IM_WINXP.txt" in the root
of the partition. In that example, it allows me to unambiguously
identify the partition based on contents. I need that if
using the Kaspersky rescue CD (with AV scanner) and I want
to be absolutely sure that the E: partition it has identified,
is in fact my WinXP C: partition. By putting a single
expressively named file in the partition at the root level,
I can figure out where I am later.

Always leave bread crumbs, for later.

I like the Cygwin version of disktype.

It's actually a small utility. It is available as source code.

http://disktype.sourceforge.net/

Being lazy, I don't really want to waste time building it
from source. So I try to find "pre-baked" versions.

I thought I wouldn't be able to do that on Windows,
but somehow figured out there was a Cygwin version.
I don't know which OS I ran that on (Cygwin installer),
and what I did is just kept the three necessary files for later.

    disktype.exe     146,139 bytes
    cyggcc_s-1.dll   103,975 bytes
    cygwin1.dll    3,197,390 bytes

And while you are sitting in a Command Prompt in Windows,
you can use a Linux-like syntax. For example, open an
elevated ("Run as Administrator") command prompt and type

    disktype /dev/sda

And that will cause the program to examine the MBR and
the partitions and print out their types for what
Windows Disk Management would call "Disk 0".

If you have a .dd or image file, you can get it
to read the MBR and partitions off that too.

    disktype macsda.dd

And this is the output I got, for a Macintosh disk image I have.
This is the primary drive in my G4, sporting 10.2 OS.

Notice I didn't get any label information. It's possible
the Linux "disktype" from Package Manager, might have managed
to display it. But I'm too lazy to disrupt things by rerunning it
right this minute.

In any case, a utility like that can give you some idea what the
partition layout looks like. And whether the unallocated area
at the end of the disk, is actually considered "FAT".

I did that with text files and volume labels since I easily get 
confused. I find it weird that Mac doesn't see them from Windows. And 
then the same in reversed when I make them in Mac and WIndows can't see 
them.

Where did you get those compiled binaries? I don't see them?

I compiled it.  Runs, but with permissions issues.  Via sudo says
"disktype: Can't open /dev/disk9: Resource busy"

It looks like that's how I got disktype for Windows.

I see I have the tarball for disktype in my Cygwin
home directory, and it was compiled there
in 2014.

It doesn't seem to have a permissions problem in Windows,
as administrator gives access to the block level interface
on the disks. So this kind of thing would work in Windows

    disktype /dev/sda

*******

"Resource busy" suggests there might be more to it than
permission issues. In this example, something needed to
be unmounted first, before the "Resource busy" went away.

You will not have problems either if you use separate drives.

What you are trying to do is doomed to fail.

OK, I messed around with this and figured the quickest way to reproduce 
this issue between platforms after playing with issue more during my 
free time. 

I had problems erasing everything on the HDD with Mac OS X's Disk 
Utility. It wouldn't even let me its remove partitions. I had to use 
Windows 7's Disk Manage to manually delete all the (partition/volume)s 
except its 200 MB EFI System Partition (not changeable?). I also noticed 
it cannot make multiple partitions in a single shot like in Mac OS X's 
Disk Utility since I had to make a big volume, shrink, make a smaller 
volume, repeat. :(

Anyways, I used Mac OS X's Disk Utility to make 3 new partitions (HFS+ & 
2 (ex or not)FAT [no NTFS option]). Everything looked fine when I wrote 
text files and checked on both systems. Next, I tell Mac OS X's Disk 
Utility to format that HFS+ with encryption. Everything was still OK in 
Mac. I go to Windows and check, and things started having problem like 
not seeing a FAT partition, files, etc. It seems like Apple is messing 
up the partitions.

I am going to reverse in creating partitions manually and slowly with W7 
first, go to Mac's Disk Utility to format an encrypted HFS, recheck, 
BitLocker encrypt a NTFS partition, and then recheck to see their 
results.

TO BE CONTINUED...
