[ale] Bad Hard Drive

[Jim Kinney]

Yeah, I forgot to mention the primary/secondary stupid mess. Some chipsets
have a primary and secondary port. So primary 2 is after primary 1, then
secondary 1 is before secondary 2 (carryover from the primary and secondary
IDE drives). I think with those chipsets, the data bus is shared between the
primary and secondary just like on the old IDE gear. So access the secondary
drive on a bus line will impact performance of the primary drive.

Server systems I use have only primary drives (except for some HP systems
who added in the secondary ports that supermicro just leaves off).

As long as the general population is passive, apathetic, diverted to
consumerism or hatred of the vulnerable, then the powerful can do as they
please, and those who survive will be left to contemplate the outcome.
