I currently have an Asus p5wd2-e motherboard with a raid 0 set up on two 250g hard drives. I will be received an MSI p7n SLI-Platinum 750i motherboard in the mail tomorrow. I want to reformat my drives and set up another raid 0 array once my new system arrives. Would it be possible for me to format the drives and set up the raid 0 array tonight, prior to installing my new board, or should I just wait until it gets here. I'm pretty sure installing windows before installing the new board is a no no, but I'm not sure about reformatting the drives first. Thank you in advance for any help you can offer me.
You would be correct... wait for the mobo. The p5wd2-e has a different chipset to the MSI p7n SLI-Platinum , and you will have to reset the RAID-0 again anyway when the new board comes in.
However, if you really need to you can format the drives now then setup the RAID-0 when the new board comes. But the only reason for formatting would be to test the drives a bit more to make sure they are still stable. which im assuming they already have been for some time
