It was the WD software that caused the problem. That is pretty standard. For some reason, people who make hardware are notoriously bad at software. If you use WD hardware without installing any of their software, it will run fine. It is always a good idea to be very stingy about giving out your admin password to some random installer. You are thereby giving those software developers complete control over your machine and all of your data.
The big question here is how you are going to do those backups. Time Machine prefers to have a disk that it three times the size of all of the data you are backing up. I have no idea if you can backup an NTFS drive to Time Machine. I have no idea if any of the cloning tools support that either. I don't know what kind of encryption your current My Book is using. If it is WD encryption, then that would be bad.

I'm using the built-in encryption in the WD My Book drive. This is because Windows doesn't have any built-in encryption. (I also considered using truecrypt, but it seemed kind of unwieldy for stuff that I need to access all the time.)
The data I'm putting on the drives is primarily music, etc. and not personal photos or documents, so for this I wasn't planning on using Time Machine (but I do use that for my personal data and my internal HD with my system). Rather I was just going to clone the data onto the second drive, so that they are exact copies of each other. Each drive is 4 TB.
However, as I mentioned above, I'm thinking of formatting the second drive (4 TB Seagate Backup+ from Costco) in the Mac Encrypted format. I suppose I could even make the Seagate drive (in Mac format) the main drive that I use on my Mac, and use the NTFS drive as a backup that I connect to my PC and chromebook on occassion...
But I guess I'm feeling unsecure about the whole thing and wondering if there is an angle that I'm overlooking that will put me in deep doo-doo later.

I am wondering if you are in deep doo-doo now.

I saw that. I was not affected (and already installed the patch), but some other users were. There was an incompatibility in the WD software that caused some people with WD external drives to lose tons of data.
But this is why I think it might be a good idea to have my backup in different format and on a different brand drive than the original... Make sense?

That is just a reason to avoid installing any software that you don't absolutely require - especially if it requires an administrator password to install. That stuff physically changes your operating system. You aren't running OS X anymore, you are running some hybrid. From that point forward, you can no longer install any OS update without checking with those 3rd party software developers first. And except in rare cases, they will not begin to look at developing for a new operating system until after it is officially released. Even then, they might require that you buy their updated hardware to get an updated driver.
I don't know about your specific case to give decent advice. It seems like a whole of needless complexity. What do you really need out of this setup? How much daily hassle do you want to accept? OS X now uses Windows-native networking as its default file sharing. Would that work?

Time Machine will not backup an NTFS formatted drive (from or to), the plan stops there.
Frankly I would use HFS formatted drivers and HFS Plus for Windows so they can read it. (Paragon again)

Frankly your best bet is to set both drives up as RAID 1 using the MAC software. This will give you 100% redundancy effortlessly. In the event that either drive craps out you simply swap in a new formatted drive and let it go for about 24 hours and it will rebuild the RAID set and you are again backed. I use it for my photos (28,000 RAW) and music colection as well as documents and financial data.
Format in the standard MAC HTFS+ system. A Wintel machine can read these disks but not write to them. In the kind of set up you discribe encription would be a hassle to say the least and you danger of data loss goes up tremendously. Just safeguard you disks.

I agree that RAID 1 is good for keeping clones that mirror each other 100% with no effort. However, this only protects you against a hard drive error. It does not protect against data loss that could be caused by malicious or defective software, or even from mistakes that you might make in indavertantly deleting data (and empting the trash).
I prefer to have my primary backup disk disconnected from the system most of the time. Something that I started doing for my primary system disk and the external with my most valuable personal data is using two encrypted external drives that I rotate. One is always offsite (I keep it in my desk drawer at work), and rotate which is at work about every month. That way, I have a second backup if the house burns down, if I get burgled, or if some malicious bug hits while my time machine is connected. Granted, I would still lose up to month of the most recent data, but I would't lose everything.
I guess the ideal sytem would be to BOTH use RAID 1 mirrored drives AND ALSO use time machine. That might be a bit overkill though.
But for the data I'm talking about here, it's important enough for me to want to hae some backup, but it's not as "irreplaceable" as my personal pictures, finanical data, legal documents, etc. so I don't feel the need to be as careful as I would with that...
What I'm leaning towards right now is to keep my current WD 4 TB external, drive in NTFS format, and set up my new Seagate 4 TB drive external drive as second time machine (using Mac encrypted format) that only backs up the WD 4 TB drive. (I'd still use the separate rotating time machine drive system
for my personal data.) Edit: OOPs, just read the post above that says that this will NOT WORK... in that case I might just have to go back to cloning it using some other software...

I use the RAID for my data. I use Time Machine to BU my Sysdisk. I additionally back both to a portable drive using Super Duper on a weekly basis. After each BU I disconnect and store the drive in a safe place.
Over the top? Maybe, but safe.
