xp pro duplicating drives on computer

First let me be clear I am a noobie / hobbyist when it comes to building and
programming computers so please be patient with me.

I'm having a problem with my computer rig. Recently received a small multi
drive unit. At first everything worked flawlessly. Now Xp is creating
duplicate or mirroring the drives in the small multi drive unit. So instead
of having 5 drives it's listing 10 in the windows explorer.

I went into computer management window and entered the drive management
screen. All five are listed and are not duplicated. How can I get XP to
recognize only the five drives without having to wipe the drives, backing up
by buying a external drive, or canning the drives all together. Problem is
there is a ton of data on each drive. I don't want to lose the data?

A friend explained it may be the raid parameters are off. However when in
the bios I can't find the screen letting me adjust it.

Here's my specs at a glance

Master unit:

Biostar m7ncd motherboard
AMD athlon 2200 cpu
1.5 gig ram
hp 420n rw-dvd
generic rw-dvd
XFX geforce 5500 128mb
audicy platinum ex
adaptec 160 pin scsi adapter

slave unit:

5 multiple drives 30-75gig each
separate power source

With respect , if you are a noobie ; why a raid array ?
