Set up RAID 1 by adding another HDD?

[desolatordan]

I have a computer running XP Pro 64bit with a 250Gb SATA drive. I want to add an identical harddrive and use RAID 1 mirroring. It has a Gigabyte GA-EP45-DS3R motherboard. Is this possible without reinstalling the OS?

Also, should I use the GIGABYTE SATA2 RAID Driver or Intel ICH9R/ICH10R SATA RAID Driver? Noticable performance difference or is one of them more dependable?

Im thinking if you change the chipset to raid mode in the BIOS, your current Xp install wont boot due to not having the correct raid drivers.

You can try to install the raid drivers, THEN change the mode in the BIOS, no gaurentee it would work though.
Youd have to read your manual to see if you can move to RAID1 without reinstalling the OS
