NOT FOR EXT HDDs. IF YOU ARE
LOOKING AT INTERNAL HDD, PLEASE READ ON
What does it mean?
Firstly, Harddisk Drive(HDD) are connected to the motherboard via
IDE(The flat, long, cable) or SATA(the small thin, long cable).
Thus, if you have only 2 SATA ports, and 1 IDE port for exmaple,
you can only put in 1 IDE HDD, and 2 SATA HDD
SO check how many free ports there are!
I think that is what the salesman meant by 'volume'.
Your friend is wrong in telling you that xp only supports
320gb,
my friend's xp machine reads 500gb.
OK BACK TO YOUR HARDDISK ISSUE:
In order for you not make any more waste trip, you
need to know that in order for a harddisk to work, you need
1. A power source going into it
2. THe Sata cable or IDE cable that will be connected to the
motherboard.
Therefore,
1. For SATA HDD nowadays, the power cord that you need to plug in
might be differrent from what your computer uses (If it is
realllllyy ooolldd like my old one)
Computers running the IDE HDD use the 'molex' connector which look
like this: [click the link]

The colour doesnt matter
However, the new SATA 2 HDD uses the powersource called 'sata
power', which looks like this: [click the link]

The one on the right is the sata power cable which you need to
connect from the power supply unit, while the one on the left, is
the data cable which u need to connect to the motherboard
IN AN EVENT where you are connecting a SATA HDD to a fairly old
computer, which have sata ports, but the power supply unit does not
have the 'sata power plugs' you need one of these:

This will be the 'satapower' to 'molex' connector, so that people
with older powersupplies can use the sata hdd without problem
ONE LAST THING, if you r motherboard does not have any sata
ports, please do not buy the SATA HDD
I told you things i know, now i tell you what i dunno, someone
please teach also:
WIll sata 2 work on sata 1 port?
