RAID 0+1

[Radomír GRYGAR]

I have P4C800-E motherboard with Promise RAID controller, which I have
configured as RAID 0 (striping) 2 x160GB harddisks as the bootable (Windows
XP) connected to Promise SATA_RAID1/SATA_RAID2 interface. Now I like to add
2x160GB disk on the PRI_RAID interface to set RAID 0+1 (stripping and
mirroring for safety). Is it possible to make it without my actual WXP
system instalation and data loose? I mean above all, if there is posssible
that bootable RAID 0 disks are linked on SATA interface and I like to add
new RAID 1 on the PRI_RAID (IDE ATA).

I can not answer for your particular board. You might consider just a
normal weekly backup. I use disk image 7 which backs up my raid to a PATA
drive once a week. It does this while I am still using the computer. This
is much better because if I get hit by a virus and am aware of it I can
restore the backup. With mirroring the virus is also on the mirror
immediately. I have found once a week good enough. If you desire you can
increase the frequency.
The more raid controllers you have the slower your computer will boot up so
keep that in mind as well.
