Win XP HE

Hi,

Just bought an external firewire hard drive.

I need to reformat and partition it properly and I have never done it
before....

Question 1) If I create an extended partition, after my primary, MUST I
ALSO create a logical drive in the extended partition for it to work at all?

OR,

an extended partition does NOT need a logical drive and no sense in
creating one in the extended partition if I will not create several
other logical drives in it.

(I suspect I do need to create a logical drive in the extended partition
for it to work at all but not sure.....)

Question 2): Completely separately from question 1) I am led to believe
that while there is nothing wrong with extended partitions, they do not
perform as well or as fast, etc., as primaries, i.e. SOME performance is
lost. True or false?

If true, then should stick to making 2 primaries in new external hard
disk if no real need for several logical drives in extended partition.
