After installing osx update 10.8.5, 

My thunderbolt duo 8tb drives don’t appear in WD drive utilites.

Using system profile tools and disk utilites of mac, i comfirm thunderbolt devices/SATA devices work correctly.

Drives in thuderbolt duo are mounted on the file system correctly ( JBOD configuration).

But, WD drive utilites says “no drives attached”.

What is problem?

Yes, see my last post(s)… You are not alone… Hopefully update coming… Same result in Mac OS X Mavericks…
