raid question

Hi, I have question about RAID 0. Currently my system has 3 hard
drives.
PATA 0 - WD 80G C: 11.4G XP-ProSP2
D: 50G Downloads
E: 13.6G Vista RC2
PATA 1 - DVD-R/W
Slave: WD 120G F: 65G Data Files
G: 50G Games

SATA 0 - WD 200G J: 175.92G Media
K: 10.38G Program Files


Ok, I'm getting a SATA 320G drive. I would like to stripe the 2 SATA
drives WITHOUT losing my Media data, the K partition I'm not worried
about. What's the best way to do this?

If you do not want to loose your media files, you must first back them up. To
set up a RAID, the hard drive needs be re-formatted with RAID header records
first.

Creating a 2 disk RAID 0 configuration, essentially doubles the
possibilities of data loss, which seems contrary to your concern for your
data. :) The reason for this doubling is because if one drive should fail,
you've essentially lost all your data on BOTH drives. RAID 0 does give you
increased performance but that should be accepted only if you're prepared
to accept increased possibility of data loss. Another thing you should be
aware of is that the size of each disk in the set will be determined by the
size of the smallest drive in the set. In your case, you'll only be able to
use 200GB of the 300GB of your new drive. Should you want to continue in
this direction anyways, you'll need to first backup all your data to some
other device, then create the RAID configuration, then move that data on to
your striped set.

Cheers.
