I use 2 Pegasus1 R4 divers mounted on a MacPro. I was working with an R4 drive and I stopped the program. After that, I could not see some files in the R4 and the drive did not respond as usual. I rebooted the computer. I can no longer see the problematic Pegasus drive by Promise Utility, finder and terminal. The other one is still working fine as usual. I can't even switch it off and the power button down does nothing. There are no errors, no red lights.

Hi Kwon, 

It could be an issue with a drive in the unit. Please contact Promise Tech support to isolate the issue OR you can also create a web support ticket in

Thank you.

I unplugged to turn off and and tuned on. Now the drive works fine.
