I think I may just avoid hdparm customizing in light of what has
happened. I like Linux alot better when it is working! I have a new
Western digital Caviar WD153ba 7200rpm.

don,t know what I am missing with all the hdparm tweaks so it doesn't
bother me that much. I know having an angry filesystem is no fun.
