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?

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".

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

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

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?

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.

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...

With the long and hard way. I did all the tedious partitioning in W7 
(only NTFS though since FAT weren't offered)) first, then go back Mac OS 
X to make a partition HFS+ with its encryption. I checked both machines. 
No problems so far! I told W7 to encrypt a NTFS partition with its 
BitLocker that took a while (no format with encryption option like Apple 
does?). I rechecked with both machines. No problems. I reformatted the 
unencrypted NTFS to exFAT in Mac OS X since W7 wouldn't let me. I 
rechecked both machines, and no problems.

Right now, I'm writing a lot of data to both encrypted drives which will 
take a while to see how these go. So far, it seems like Mac OS X's Disk 
Utility messed up my partitions when doing encryption after creating 
partitions instead of having MS W7 do it slowly?

TO BE CONTINUED AGAIN... :/

So, I changed to another adapter and now 64-bit W7 EE SP1 cannot see the 
partitions (wants me to format it). However, Mac OS X v10.10.5 
(Yosemite) had no problems. Argh.

you’re going to have problems with the partitions. Apple uses GPT, Win7 
usually uses MBR. GPT systems can see MBR partitions. MBR systems can 
(usually) see GPT systems which have one partition. More than one partition, 
not so much. You will experience problems with GPT partitions on 32-bit Win 7 
systems, and different problems on 64-bit Win 7 systems which have older 
BIOSes rather than UEFI. See 
https://en.wikipedia.org/wiki/GUID_Partition_Table

I suspect that your Win 7 system uses MBR. I really doubt that you’ll get 
an MBR Win 7 system to see your partitions.

Frankly, if I were trying to set up an encrypted USB device which could work 
on both Mac and Windows, I’d simply use NTFS and get one of the extensions 
which allows OS X to read/write NTFS. There are, or used to be, several free 
NTFS extensions, and there is at least one pay version, from 
Paragon.http://www.paragon-software.com/home/ntfs-mac/
Alternatively, I’d get a virtual machine (Parallels, VMWare, Virtual Box) 
and put Windows in it on the OS X machine, and read the NTFS drive using 
Windows. Finally, I’d try formatting the drive HFS+ and getting a HFS+ 
read/write extension for Windows. Paragon offers such an extension, too. 
http://www.paragon-software.com/home/hfs-windows/

I used to use two of the free NTFS on Mac extensions, was dissatisfied with 
the performance, bought the Paragon extension and have used it for several 
years now.

I suspect that it will be difficult to impossible to put two partitions, one 
HFS+ and one NTFS, on a USB device and have them be actually useable.

Interesting. I am surprised it is not possible to do multiple partitions 
like that like with internal drives. Do Linux and Windows have this 
problem too? :(

FYI. Reusing the original adapter had no problems. Just can't use the 
other ones. :/

sure it’s possible to do it. You merely have to use the right partition 
table. Win 7 and earlier prefers MBR. Win 7 and earlier, and all 32-bit 
versions of Windows, won’t boot off GPT. You can have four bootable 
partitions with MBR, 128 bootable partitions with GPT. What you can’t have 
is MBR and GPT partitions on the same drive, internal or external. And you 
can’t boot Win 7 off GPT, and you can’t boot an Intel Mac off MBR. Win 7 
will apply MBR unless you force it not to. OS X will apply GPT unless you 
force it not to. If you were using Win 8.1 or Win 10 and had the correct 
hardware you could format the USB drive with GPT and it would probably work. 
Not Win 7. For one thing, you are unlikely to have the correct hardware on a 
Win 7 system.

If you have just one partition, either system will load it regardless of the 
partition table. Internal drives very rarely have just one partition these 
days. A typical Mac, for example, with have at least two: the repair 
partition, which is hidden, and the main partition, which is the one you see. 
If you have Boot Camp set up, you’ll have at least three partitions. All of 
them will be GPT. Win 7 required hardware settings, in UEFI, to boot from a 
GPT volume. Apple supplied them to Boot Camp. Without the proper UEFI 
settings, Win 7 will not boot from a GPT volume and will have problems with 
it. Systems which have the correct UEFI settings are almost always set up to 
boot UEFI. The GPT settings are in hardware and in software, you have to have 
both. if your Windows hardware does not support UEFI you are extremely 
unlikely to be able to boot from a GPT volume and you are extremely likely to 
have a problem accessing a GPT volume which has more than one partition.

Well, mostly because dealing with partitions across different OS' is 
madness and because disks are cheap, I'd put each "partition" on their 
own disk.  Would the Linux system be able to read/write to the NTFS 
disk, yes.  But if it's encrypted, that's doubtful unless there's a 
Linux version of the encryption software.  If the NTFS volume is being 
encrypted by a native feature of Windows, I would tend to doubt it.

Same for Windows reading and writing Linux partition (ext3, ext4, zfs).  
And AFAIK, there's no native encryption for those filesystems built into 
Linux. It would have to be something added after the OS is installed.  
Truecrypt (depricated May2014) was forked to become VeraCrypt.  
VeraCrypt does support Windows, MacOS, and Linux and will allow you to 
make encrypted volumes on those systems.  Being able to read them 
natively across each other depends on how you access the volume across 
the different OS'.

But doing the native version of FileVault on MacOS and BitDefender on 
Windows, I doubt it, even with separate drives for each filesystem.

You meant BitLocker. ;)


> Windows, I doubt it, even with separate drives for each filesystem.

I was OK to have other OSes not see the competitors' encrypted datas 
like W7's BitLocker can't see Apple's FileVault datas and Mac OS X 
v10.10.5 can't see W7's BitLocker data. I just wanted to be sure that 
they don't get lost when I switch between adapters and computers which I 
ran into. Also, I have a third partition, FAT, so that any OSes can 
access data. This is a lot more complex that I thought it would be. :/

As I recall, several people here told you that you could expect problems,
yet you marched on anyway.

to me it seems that your adapters have different capabilities.
Get some more of the adapters that work under all conditions and trash 
the others.

Cheers

Which adapters would that be? There are so many. Any recommendations 
that I can always rely on?
