I Have this:

MBP 2011, OSX Mavericks.  

Hooked up via firewire is a daisychained :

MyBook Studio 2  (6tb, 2 TB drives, i configured these to RAID 1)

and

MyBook studio all via firewire (3tb single) - encrypted with OSX.

Suddenly one day, after I restarted my computer these drivers show up as “MyBook” and “EFI”  (although now it no longer shows the efi, it just shows up as mybook).  They show up as 3TB FREE.

I called tech support and they were no help at all.

“well it looks like all your data is pretty much gone, sir, I’m sorry to say”

“you mean, my RAID 1 and other single MyBook studio just decided to fail on me at the same time?”

“yes, sir”

I’m feeling you bro, WD seem pretty, pretty, pretty, uninterested in looking in to this. 

It’s all over the internets!!

I have exactly the same problem with „MyBook Studio Edition II (6tb, 2 TB drives,RAID 1)“ after the OSX 10.9 update on my Mac Pro!

Yesterday it worked fine, today it shows up „MyBook“ and “EFI“ and all 3 TB data are lost!!!

I think that there is a big software bug! WD please help to find the problem quickly and find a way to get the data back!

Update:

WD has contacted, with the case “escalated” to a higher level tech support.  The guy was very good and took down all the pertinent information and it seems like they are really looking to the situation.  He said he will get back to me and the information has been forwarded to their engineers.

the story is on the front page of macrumors.com now
