BIOS and On-Board RAID controller

Hello community!

Let's say you're using a cheap, nothing special on-board RAID controller and not a fancy RAID card of some sort. Do you lose your RAID array when your CMOS battery is removed/dies?

No, you should be okay, the RAID configuration info is stored on the drives themselves. You might have to re-enable RAID mode in the SATA controller settings, but it should auto-detect the configuration.

 

I'm not positive, though. If this is totally wrong, someone correct me!

Hello community!

Let's say you're using a cheap, nothing special on-board RAID controller and not a fancy RAID card of some sort. Do you lose your RAID array when your CMOS battery is removed/dies? Also, let's say I tried to do some crazy overclock and failed miserably. I then can't get my system to POST and I need a BIOS config reset to get everything running. Do I lose my RAID array by doing so?

Should this be the case, can I regain my array by doing a bios restore from bios config backup?

I want to know because I want to gauge how much should I trust the redundancy provided by my RAID array that's currenty running on my motherboard's on-oboard RAID controller. I'm regularly chaging stuff in my BIOS and i'm beginning to worry that I may lose the array if I mess up.

Of course, i'm taking regular backups aside from RAID.

Thank you for any input.

No need for corrections. That's pretty much all there is about it. :)
