Answer 1. The normal Windows Update will list SP1 unless
there was some problem. You can download it for free from
Windows Update Catalog/ Windows Downloads.

Answer 2. An external USB 2.0 drive will work better with
your system because of the limited internal space. It also
has the advantage that you can back-up working files and
take it with you when you need a secure copy of important
data. It also will allow you to take your work with you.
Answer 3... Firewire, aka IEEE 1394 is a very fast (speed
about same as USB 2.0) means to connect devices to a
computer. It is common on movie cameras and Apple calls it
iLink. You can get a Firewire card IF you have available
PCI slots.
| Thanks, everyone. So much info, so few remaining brain
cells! ;-)

| Two more questions:
|
| 1. How do I get SP1? Do I just download it from
support.microsoft.com, or
| will it cost money? I checked My Computer -> Properties,
and it says
| nothing about SP1 so I assume I don't have that.
|
| 2. If I go with an external USB 250 GB drive, will that
obviate all these
| issues?
|
| On a probably unrelated topic, what is firewire?
|
| TIA,
