There's more to greens than that. Apart from not having error recovery, 
they also apparently have a habit of going to sleep. Search the list for 
greens, but you need to do something else to stop them going to sleep, 
as that will also interfere with the raid.

I'll probably be adding that to the wiki at some point - I want to add a 
section on drives readily available, with that sort of information.

Cheers,
Wol
