It's possible it has to do with the power outage, did it work previously? And did you try mounting it from within Disk Utility?


Here's another way you can try to mount it:

Launch/Utilities/Terminal and copy & paste this command at the prompt:


mount /dev/disk3s2

Press Return.


Also might try

mount force /dev/(number of disk)
