Yeah, that'll help kill a disk, I am on the Ubuntu 9.10 "release" version 
of mythtv and haven't seen the "ticking disk of doom" problem.

Also, what are your data rates to the disk, for DVB-T I tested the rates 
yesterday and SD (576i in Oz) it is 0.6 MBytes/sec per recorded stream, HD 
is 1.2 MBytes/sec/stream (stream=1 recording, i.e. 1 program).

I am still going to have a play over the weekend in a WAF compatible time, 
and see how many recordings it takes to break by disk!

Any votes on a good DB intensive task to run as well?
