Being a RAID 1 and not a RAID 0 you could just take the drive out and your OS a data is safe and will run like a single drive the problem will be to add a HDD without the raid rebuilding on it which shouldn't happen if you reformat drive and have data on it.
I'm not sure I understood you. I know I can remove one of the raid disks and the remaining one will keep it's data - it'd just be in a degraded state. But I figured that wasn't ideal...and so somehow wanted to get back to no raid at all. Is the strategy I outlined above going to make that goal possible or not? With some adjustmen, of course.
I for sure didn't understand the last part of what you wrote re the problem being adding a hdd without raid?
Encouraged by this post (http://communities.intel.com/message/13312#13312) which has some reports of resetting raid 1 without losing data, with the 'clone' hdd installed, reset the raid and set the ami bios to configure sata as ide. The drive now appears as a sata drive in the bios and is listed #2 in the list of boot devices. However, after rebooting the system still reports that there is no boot device.
Is that a by product of the cloning process with which this disk was created? Can I make the disk bootable? Or should I turn on raid again in the bios and raid config screen, put back the remaining raid member, and undo the raid settings again?
I just tried booting from the ex-raid disk and it seems that it's bootable, intact, and no longer thinks of itself as part of a raid array.
So it seems likely that if I'd simply reset the raid, I'd have been able to boot from either independent disk? And the reason my attempt earlier today was that somehow the cloned hdd was not bootable.
I'd really appreciate any input on these question:
- Why wasn't the cloned disk bootable? Could it have been made bootable?
- What are the exact steps to un-raid a raid 1 set? Is the correct order to reset raid in the raid config screen, then reboot and in the ami bios change IDE Configuration to Configure SATA as IDE? Or the other way around?
I'd sure appreciate it if someone with more experience would provide some input on the questions I posed above, even though my specific situation is resolved.
