Eh?

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.


OK.

Thanks.

I like the Cygwin version of disktype.

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

http://disktype.sourceforge.net/



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.

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

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...

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)!

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

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... :/

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?

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.

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?


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.

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

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. :/


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?
