MySQL won't start after battery failure

[NICHOLAS ROPER]

Hi,

I run MySQL 5.6.12 CE on a Macbook (Mountain Lion)

Earlier today the Mac shutdown unexpectedly and it seems that there has been a battery failure.

I can restart the Macbook with power plugged in but now I am getting errors when trying to run the mysql client. It would appear that MySQL is not running and I get output shown below. Have tried switching to root and running but still no joy - any ideas would be great.

Thanks,

Nick
