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?
