Hi Guys!
This morning, while doing research for my exam-prep course, I found out
something that I had never before noticed. That is, that on Ubuntu
systems, old-fashioned PATA hard drives are designated as "/dev/sd*"
rather than "/dev/hd*". I did a Google search, and found that that's
because Ubuntu uses the libATA library for mounting drives.
That's true only for some parallel ATA drives, the ones supported by
libata. So for some machine you will still find /dev/hd* depending on
the chipset.
But I agree that libata and such kind of problems should be addressed.

Yes I agree that there is something to be addressed but I disagree that
it is libata and the way it refers to disks.
I think an admin who finds any device name in /dev should be able to
work out what module in the kernel created it.
Then using that information can establish what it is.
Effectively admins should have the tools available to use the
documentation available.
Otherwise we have to provide incentive for people to learn the possible
device names for all hardware drivers.
So if you want to have questions around /dev/sda1 etc. then make them
something like:
You find the device /dev/sda1 which of the following would tell you
which driver created this device ...
and
You know that device /dev/sda was crreated by the bob driver where can
you find out more about the bob driver...
My 2 cents.
Chris.
