I am dealing with a Pegasus2 R6 problem, wondering if anyone had similiar experience.

Mid March, the office had an power outtage, and the Pegasus2 won't mount after power was restored. Disk Utility does not see the Pegasus, System Profiler does see it on the thunderbolt bus.

Pegasus Utility would not open a window. 

After couple hours of troubleshooting, as a last resort, I powered down the Pegasus, and reseated every drive. turned the Mac back on and the Pegasus came back to life, volume mounted on the desktop. 

That lasted a few days, now the volume won't mount.

I think the enclosure is bad? How do I diagnose the enclosure?

Thanks in advance.

Hi Ed,

In order to find the exact problem please register yourself as a user @ and open a case with  latest subsystem report.

3) Click the lock symbol on the left bottom corner of the screen to unlock the utility.

4) Click on save service report button to save the subsystem report.

Thanks !
