I just lost my main audio library hard drive as well.  No chance of
recovery, but I have been wanting to re-edit from scratch anyway.  So
sitting here for the next month editing and building stuff is what I
guess I am up to.  Unless I fall into a project that I can not turn

I have run hard drives for fax and v-mail for a number of years and
it does not seem to matter the rpm or physical size.  They all seem
to die for me from 4-6 years on continual spin.  That is unless some
project becomes important and very time critical.  Then the drive
seems to know to die then.
