Dear Neil,
You don't know me, but I wanted to write and
thank you for such an excellent article on
hard disk partitions. You write with a style
that is very clear and, shows how much you really
do know about the subject. I taking the liberty
of sharing this message with the Eudora users
list which I recently joined. Everyone will
benefit from reading, and saving, your great
article. Thanks again! I hope the list will
forgive me if I am too far off topic, but your
article is just too good to miss.
Keep up the good work, please!!

p.s. A measurement technique now follows,
with annotations to explain the derivations.

Grier,
Here are the results from your command sequence
on the two partitions I have on a 486 tower PC.
Many thanks for the great tips!
