Basic Raid Controller setup question. Please Help!!

[tekparasite]

I am new at this Raid configuration stuff. I have a "not so fast" PC running windows XP Pro with 3 hard drives. One 8 gig and two 120 gigs. The 8 Gigger has the OS. The raid I'm trying to create is simple. Raid-1 (mirroring) of the two 120gig drives. I have an IDE raid controller PCI card by Silicone Image. I installed the card, drivers, and some software that came with it without any problems.

However, everytime I reboot and get to the OS, I get an "event" notification by the software. When I look into it, I see that my back up drive is being rebuild. Several hours later, I see that both of my drives are now "Current", but if I reboot, I get the same notification again and another rebuild. Why????
Is it the way I have configured the Raid-1???

When rebooting and after POST, I get prompted to press F3 to enter the Raid setup utility. These are the things I have done:
1) I selected that I wanted to create a new array set.
2) Then I selected the type: (Mirroring set)
3) Selected the two drives, and selected which one I wanted as source and which one as backup.
4)Then I got prompted with the following questions:
Do you want to copy from the source drive to the destination drive?
Ans: Yes (and I do because my source drive has info I don't want to loose)
Do you want offline copy?
Ans: (don't know what this means but I have tried it both ways: Yes and No and I still get the same "event" notification problem).
Auto Rebuild Enabled?
Ans: Yes
Are You sure?
Ans: Yes

Is this normal for a RAID-1 setup?? that everytime, you reboot the source will always be copied to the backup?? Is it because of I have enabled Auto Rebuild?

Please help

i believe auto rebuild is your culprit.

as far as my understanding about raid goes, when the 2 drives are mirrored, they are identical after a rebuld is complete. once 1 rebuild is done, there shouldnt be aneed for annother unless there is a system crash.

Try disabling the auto rebuild and see if it gives you the event.

It may just be stating that it is copying from one drive to another initially. It takes a long time to start mirroring drives.

Thanks for your reponses guys. Davis, I did what you recommended and disabled the auto-rebuild and that event notification went away. Everything seems to be working fine.
