I probably not the only lucky one. Not readable drive after firmware updated, and installed smartware 1.3.3.6.
Configuration:
iMac, MacOSX 10.6.7
WD studio 1.5TB / 2.0TB
Smartware was: 1.2.2.5 > 1.3.3.6
Firmware was: 1009 > 1012
Strange thing is - it works fine with my WD studio 1TB!
Please help if anyone who has got the solution, I really appreciate it!
