I want to switch my 2 (3TB) HDDs (non-bootable, just data) from Windows mirror to Hardware RAID 1. But I don't know if it will wipe out both drives in RAID building process, I'm ok if it erases one of them but I really don't have any place to copy all the data first

It's Marvell 9128 RAID (SATA3) on Gigabyte X58a-UD3R (Rev. 1) motherboard.
From the manual it's not entirely clear if not enabling "Quick Init" will not erase all data.

BTW reason I don't want to use Windows software RAID is when I have computer crash mirror get's broken and starts to resync which with 3 TB drives takes about a day! That's a good way to wear our the drive

Yup, It will erase everything during the process of building the raid 1 array in the bios. It will warn you first before it kills everything on the drives.

Mirrored raid and raid 1 both work the same, and yes, it will take a day to rebuild a drive in raid 1 also....and no it is not going to kill your drive to do so.

Copy everything you need over to another hdd, internal or external...it makes no difference. Then reconstruct your Raid 1 and and put everything back where you want it.

That statement pretty much says it all kleinkinstein.

He simply cannot do what he wants to do with the resources he has.

Actually I eventually found room on another HDD to copy all of it (and deleted lost of old crap in the process). All of you were right it did erase everything, thanks!

I'm so much happier now with hardware RAID.
