Hi,

I have re-tested the verify using the 'C' protocol rather than 'B', in 
same way on same hardware on same load, by simply repeating the verify 
over and over.

I am glad to say that I have had no new bad blocks with 'C'.  Although 
there are some messages in the logs you may want to see.  I hope this is 
useful!

Regards,

Ben
