Thanks Mark.

I've tried with the 16Gb that previously worked, built from scratch again, it failed and gives what looks like to be a very similar boot sequence to the first log I posted above. Also does almost exactly the same with the original drives in.

So would you think some of the hardware has gone bang? This line makes me think that...

"smc_init couldn't find card"

I saw a previous post on here somewhere about that maybe being a result of a chip in the IDE interface going bad?

Cheers
