Count me on this, too.
After the inital install of Mavericks everything was okay.
After restarting "Poof" Data gone. The WD Raid Manager kicked in and all was lost. Now there is one partition called EFI and one called MyBook.
Interestingly my USB Stick, which was connected too, showed three volumes, instead of one (EFI, OSX Boot, Data).
Edit: I checked the MyBook with the HD Utility from OS X. It told me that the Partition Scheme was damaged. So I repaired it. After that I wanted to make sure, that the RAID 1 was still working. So I started the RAID Manager from WD and build a new RAID 1. Guess what? After finishing there was the EFI Partition visible again and the HD Utility told me again, that the Partition Scheme was damaged. For me this looks really like that the WD RAID Manager is the culprit. I uninstalled it and hope that my RAID is working nevertheless. At the moment I make a new backup of my System.....

At this point I would like to know if WD and Apple geniuses are working on ANY, ANY way of reversing what went wrong to bring the original volume back and yet they are still silent.
I never saw anything like this. It's just a hard drive for god's sake! It is unbelievable that the drive is erased without any warning! It is unbelievable that WD did not test their software on prerelease Mavericks! I still don't see any warning on both WD and Apple web sites!

I am in the same situation, cannot find any data on the My Book Studio, this is ridiculus.
I am also using Maverick I wish I never upgraded.
If this does not get resolved soon I will never buy WD product again, even though up till now I have had no problem in the past, but I have not got the time or patience to put up with this. I am running a business and now I cannot get some files, just great

One question: Was the WD Software installed on your Systems? As I wrote, in my opinion it looks like the Software is to blame. Seems it kicked in and destroyed the Partition Scheme. Sort of incompatibility with 10.9 I guess.
At the moment I am running my WD MyBook Studio II again. It works flawlessly with 10.9 again. But I uninstalled all WD Software from my Mac. Had a few restarts since then and everything is fine.
I "ONLY" lost 2 years of backup.....
I opened up a support ticket at WD. I am curious how they will respond. Yesterday I phoned wit Apple Care. I talked to 2lv support. And no one there ever heard of this problem with 10.9. So the ball is with WD I think....
I think it really is a desaster that they did not test their Software. I even checked back with their Support Site before updating to 10.9. They wrote, that everything is compatible.....

I opened up a support ticket yesterday and am waiting for the reply.
I installed WD Drive Manager on my MAC. I think that's the only way to configure WD MyBook Studio II as a RAID 1.
There's not only backup data in it. There's important data in it and that's why I use it as RAID 1!
I'm very very disappointed at WD. There's not any reminder or discription about the issue. Mavericks has been released 9 preview editions!

Another issue with WD warranty now.
As per my original post my My Book Studio II defaulted itself suddenly 5 days after installation of Mavericks and after two dozens or so shutdowns, restarts and cold starts.
Contacted tech support on Oct 6 - case # [Deleted] and after a lot of tests and tries got the RMA# [Deleted]
WD received my drive on Oct 17
On Oct 25 I contacted tech support for the update and was told that the delay in sending the replacement is due to the lack of WDH2Q4000's in the inventory and was offered a My Book Live Duo or the Thunderbolt one as replacement - I agreed and was put on hold for several minutes.
After several minutes on hold I was told that another WDH2Q4000 was found in "different inventory" and will be shipped to me on Monday, Oct 28.
Today, Oct 28 I checked my RMA status and it was updated with shipping info for the perlacement unit. And here is the problem:
My failed unit was purchased in May 2013 and had a warranty until May 2016 - the serial number [Deleted], you can check yourself.
The shipped replacement unit has a serial number [Deleted] with the warranty expiration date 2/25/2014 - it means it is a unit which was already used more than 2 years longer than mine. It also means that disks inside will just die very soon.
Called the support and was told that warranty on replacement unit will be extended to the same expiration date as my original unit. When asked in the replacement unit got new disks inside I was told that not, they are old ones but "recertified". I furious about getting "recertified" disks and more than 2 years older replacement unit - I don't care that warranty will be extended. It is not about the warranty!!
My original unit had over 1.3 TB data on it, including over 900 GB of iTunes library. Yes, I can redownload content of iTunes library, but it will take few months worth of my ISP monthly usage cap or I will pay extra charges for exceeding my cap. Not mentioning that 900+ GB will take a long time to download. And then the old, "recertified" disks inside the unit will likely die anyway. Then I will get new RMA and another "recertified" unit, who knows how old.
I expected and still expect better from WD - if the RAID controller failed in my less than 5 months old unit I expect getting a new or at least newer replacement unit, not over 2 years older!!!!
Shame to WD for treating customers so badly.

Same to me. All data are gone after installing the Maverisks. I can read the content after installing Maverisks. But after I start my iMac tonite, all data are gone. But, the data in other WD external disk are still there. Only the one with raid 1 are gone.
I have many years photos there. All are gone? ><''''
