Megaraid PERC4 check consistency problem

[Patrick_Boyd at Dell.com]

If nothing else is wrong it would most likely be parity errors. This can
be caused by power loss.

Hmm that's not very helpful of it!

So what's worrying me is what type of problem has it fixed?
Are these bad blocks on the disc? Places where the RAID parity
is wrong?  MegaMGR is saying that for every drive there are no
predictive failures and that they have a 0 error count - yet
something has happened on the last two consistency checks.
