Sorry, I don't know a solution for this.

I just want to say that I have the same problem with some machines. 
Apparently this is not a hardware problem (or not an obvious one...), 
since the HDDs are fine, no errors etc. Is that from time to time it 
produces this error. More frequently on a machine which has 8 HDDs on 
it, but the same thing happens on other machines with just one HDD on it 
(and different motherboards, CPU, etc.).
