A couple of other things regarding this
thread. The external USB drives are significantly faster than any CDR, I
can copy a 180mb file in just a matter of minutes without any problems. I
have used CDR's in the past for data backup and have had problems reading the
data afterwards (not immediately but several weeks-months later and not on all
CD's), try reading an archived CD to make sure that they are still
readable. IF you are going to install a second or even third hard drive
into your case you had better make sure that there is plenty of air flow to the
inside of the case as the newer faster drives do tend to heat up. Bottom
line, decide on some type of a backup and use it religiously as it's only a
matter of time before you have to restore your data.

Opps, Forgot to mention this.....Yuki, you
say:The odds of both the internal and external goingdown at the
same time have to be pretty small I would think. Notimpossible, but
pretty small.And yes I agree. But this is not the point of
backup.......What if, You accidentaly erase some important file in your
system.And I mean realy erase - Empty trash - And have done alot of disk
writing since.You think - Oh no worries - And plug your USB drive
in.Ah there's the file - Hmm, But the directories have some wierd glyphics
in it....Oh well - You go ahead and Copy the file. Pop it in it's
proper place....Well I guess you know the rest of the story..... You'd
wanna hope that 3rdUSB drive you bought has some current data on it.
