new pair of speakers that are
absolutely great, but the problem
is that when I play my MP3s
the sound crackles and pops. I
think the culprit might be the
onboard RealTek AC97 on my
motherboard. Is there anything I
can do to fix the problem? I’m on
a tight budget so I’m hesitant to
purchase a stand-alone soundcard,
but if I’m forced to go that route,
are there any quality, value-priced
5.1 channel soundcards out there
you could recommend?
—MARCEL DORMA


You should have no problems playing
MP3 files on a properly configured
system, even if it’s using lowly
onboard audio. The crackling is likely
the result of a device that’s hogging
the PCI bus. You may first want to
check your device manager to see
if everything is configured correctly
and there are no conflicts. You may
also want to try removing your PCI
cards (NIC, RAID, modem) to see if
that clears up the problem. Of course,
also make sure you have the latest
drivers and BIOS for the motherboard
and sound device. And get the latest
drivers for all your hardware devices
(NIC, RAID, modem) as that may cor-
rect any problems. Finally, if you’re
really into high-quality sound, you
shouldn’t be running onboard audio.
Consider Creative Lab’s Audigy 2 ZS
(about $85) or M-Audio’s Revolution
7.1 card (about $75.) Both feature
high-quality 24-bit components
and because they’re off the moth-
erboard, they’re less prone to the
noise that most onboard AC97 com-
ponents demonstrate.


DEFRAGGING RAID
I’ve got two Western
Digital Raptors in a RAID 0
configuration and was curious
as to how defragging affects
performance. Whenever I have
the defrag utility analyze my C:
drive, there’s always an inordinate
amount of info on the latter half
and I want to know if the cleanup
process sends all the data to a
single drive, negating the benefit
of splitting the labor, or does it
clean everything up and keep data
spread across the two drives?
—MIKE FONTANA


A RAID array is effectively a single
drive as far as your defragmenting
software is concerned, so we rec-
ommend treating it just like a single
hard drive and defragging relatively
often (at least once a month). When
you perform this task, the software
treats the two drives’ data stripes
just like bits of data on a single
drive and rearranges them in order
to be as contiguous as possible for
optimal performance. We’re not sure
what’s causing you to think most
of the data is residing on only one
drive, but that would never happen
with a RAID array and is physically
impossible because RAID striping
works by dividing data into blocks
and divvying it up between the
two drives. In RAID, data is always
spread across both drives by the
RAID controller.
On a semi-related note, be very
careful running RAID 0 because it
doubles your chances of suffering
drive failure and losing all your

data. In general, you should never
keep anything on a RAID 0 array that
you would mind losing.

TO RAID OR NOT TO RAID
I’ve recently gotten into video
editing and now want to
upgrade to a dual SATA drive
configuration. Everything I read
about video editing says the ideal
situation is to have two hard
drives with the OS loaded on
one drive and the video files on
another. How does this compare
with a RAID 0 configuration that
has two (or more) partitions?
—FRED WILSON

Because you’re doing video edit-
ing with your PC, a RAID 0 configu-
ration is ideal for this purpose. As
you are probably aware, stream-
ing video requires some serious
horsepower, especially if you’re
trying to render multiple streams
at once. If your hard drive can’t
write as fast as the speed of the
incoming video stream, the result
is dropped frames, gaps in audio,
and jerky performance. This sce-
nario is highly unlikely in a RAID
0 setup, as both drives can handle
an obscene amount of bandwidth
(more than 100MB/s sequential

reads for late-model hard drives!)
and are thus totally capable of
handling any major spikes in
throughput as well as multiple
streams simultaneously. The only
problem with the RAID 0 approach
is it doubles your exposure to
catastrophic data loss, so you’ll
need to run frequent backups.

UPDATING DRIVERS
AUTOMATICALLY
Do you know of a way I can
automatically detect the
hardware in my system and
locate the correct or updated
drivers for the components? I
recently reformatted my hard
drive to reinstall Windows 98
and it’s a pain to have to hunt
down the drivers I need.
—TODD

That would sure be swell, wouldn’t
it? Unfortunately, we know of no
such beast, and we’d be very cau-
tious if we found someone advertis-
ing such a service. A site that would
install new drivers when Windows
is freshly installed could also install
all sorts of nasty malware when your
computer is at its most vulnerable,
before the firewall and antivirus soft-
ware are onboard. n

HARD OF HEARING
I jog regularly in Central Park
and always take some music
along to keep me going, but
the volume levels are never
loud enough. I’ve tried using
both an MP3 player and my
Samsung SPHi-700 phone.
I have tried to enhance the
audio levels of my WMA and
MP3 files via MP3Gain but
the audio becomes static or
noisy. Is there a way for me to
enhance the audio level of a
song without distorting it?
—ALEX

In a word, no. MP3s, as you
probably already know, are com-
pressed by throwing out a certain
amount of audio data in order to
reduce the file size. You can use a
program like MP3Gain to increase
the volume a little bit, but you
can’t crank an already com-
pressed file to Dr. Feelgood levels
without some consequences.
You have some options,
though. You can rip your CDs over
again and use an audio-edit-
ing application to increase the

volume of each track
(look in the Help file
for “volume increase”
or “gain” control)
before compression.
But that’s a drag.
You can also buy
better headphones.
Sony’s MDR-EX70LP
and MDR-ED268LP
series earbuds ($50,

pump incredibly
juicy bass from even
weak-sounding, poorly
compressed tracks,
while remaining light
enough to be comfort-
able for jogging. Even
better, Shure’s E3c earbuds ($100,
http://www.shure.com) provide a better
fit, blocking out more outside noise
and thus reducing the amount of
volume you need.
You also have the option of
buying a louder MP3 player. The
iPod gets brutally loud (fun fact:
European iPods are quieter, for
sensitive European ears). And if the
iPod still isn’t loud enough for you,
crank it up with euPod , a third-party

There’s no easy way to
increase the volume of your
MP3 files, but you can get a
louder MP3 player. The iPod
is one of the loudest players
we’ve ever tested.

an inverse relationship between
volume and battery life).
