Very true about the 193 count. Here's a drive in a system that was
built in Jan., 2010 so it's a bit over 2 years old at this point. It's
on 24/7 and not rebooted except for more major updates, etc. My tests
say the drive spins down and starts back up every 2 minutes and has
been doing so for about 28 months. IIRC the 193 spec on this drive was
something like 300000 max with the drive currently clocking in at
700488. I don't see any evidence that it's going to fail but I am
trying to make sure it's backed up often. Being that it's gone >2x at
this point I will swap the drive out in the early summer no matter
what. This week I'll be visiting where the machine is so I'm going to
put a backup drive in the box to get ready.
