Not really, just a read error on a block number.  I don't think it's the same 
block each time.

Are you suggesting that three different SD Cards that works perfectly every 
time on a Raspberry Pi could 
be susceptible to failure when plugged into a Zero, because of the load caused 
by the WiFi driver?  (I use 
the same WiFi dongle on the Pi 2.)

Wouldn't that show up for other Zeros and be all over the forums, unless it's 
caused by a fault on my 
particular Pi?  BTW.  It's difficult to use a Zero without WiFi, because the 
device has no Ethernet port.

Never forgetting that I've had this working on the Zero occasionally (although 
I installed to the SD Card 
on the Pi).

Wouldn't this also be an issue with the Pi 2?

Thirty third time!

If Peter's Zero runs PiCore OK tomorrow, I'll try it on my own Zero.  PiCore 
runs very little by default, 
although it does load Midnight Commander and SSH by default.  My installation 
also includes Python 
and RPI.GPIO but it boots into a shell and starts running the Lighting software 
(on the Pi 2) in about 15 s.
