rebuild a raid 0 array in bios after removing

I have a server running raid 0 configuration. I'm getting ready to upgrade it to new hard drives, and will be taking the server down for the upgrade process.

Since I'm putting new drives in, I'll have to re-create the array before install, which is fine. However, since both of the original drives are still functional, I wonder if it would be possible to reinstall the originals if there is a problem with my new build. I mean, I will have erased the information from bios, but all of the data is still on both drives.

It depends. I would definitely recommend labeling the drives as to which slots they go into (and verifying that when you update the BIOS).

If you set the BIOS to a RAID 0 config before the old HDDs are re-activated (so to the BIOS there is no noticed change) it should recognize a valid RAID 0 config and not try to rewrite any data. Theoretically, though - I'd definitely recommend saving the data (and not the drive architecture), so that it can be restored no matter what the config.
