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? :(

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'.

http://veracrypt.codeplex.com/

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?

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