Sara2000,
     you are trying to preserve the data that is not on the OS drives?  or do you want to scrub the data portion?

preserve= have a good backup and test it before the server goes out

scrub= issue the following command

dd if=/dev/urandom of=/dev/sda bs=1M

replace /dev/sda with your partition info.

afterwards I would break the data raid, mix the disks and then rebuild and initialize.

Boot a computer to a Linux distribution and then enter dd if=/dev/random of=/dev/sdb bs=64k

Watch The boot to make sure that SDB is the appropriate device name for the raid array

Make sure you configure a large RAID that includes all of the disk drives that you have.

The raid array type doesn't matter because this command it will write random data to every bit on the raid array and the parity that will be calculated in the unexposed areas will also have random data.

Don't forget to incorporate any hot spares into the array so they are destroyed as well

If you want to be absolutely sure, use format utility (dban),  http://www.dban.org/  Dariks Boot and Nuke. Check: http://www.techrepublic.com/blog/five-apps/five-hard-disk-cleaning-and-erasing-tools/

in short.. if you delete the RAID then yes your data will be wiped. so take the backup or deploy it on other hdd
