[mythtv-users] 'wa' field in 'top' is +90% when recording a show

I've noticed that sometimes when I'm recording tv and when watching certain
shows I've recorded, the cpu is pegged at 99% or 100% with most of the
utilization in 'wa' (wa stands for "I/O wait state"). I record a lot of HD
content so I have two 250 gig drives and I use LVM to make the two drives appear
as one to mythtv. One of these two drives is a refurb (didn't realize it until
after I bought it) and I suspect that I'm only seeing the high wa utilization
when I'm accessing the refurb drive.
How can I verify which drive a show is stored on in a LVM enviroment? Any other
ideas on what could be causing wa to go sky high? Trying to playback a show
with the CPU hammered like this doesn't work very well.
