It sounds like you got your computer booting, if so, congrats and I am happy for you.
The thing about RAID 1 is that if you have one hard drive go out, theoretically, you are supose to be able to just take out the failed disk, and switch over to the second one and go on with your business. It does not protect you at all from a failed or corrupt operating system, just a failed hard drive.
RAID 1 might slow you down a little bit, but not much, RAID 1+0 is suppose to help there not be a slow down and is the preferred RAID setup for mirroring. I read something that called it the Cadillac of RAID, lol. I have found some good articles about it and if I get the chance to find them again, might even be in my favorites, I will post them here for you.
Louis gave me some really good advice for how to undo the RAID, but I have still not actually done it. He said one could elect to not delete the array and just remove the second drive from the computer, and then remove the RAID card and then reformat the drive and later install the second drive. I was wanting to reformat the main drive but not lose the data from the second drive and since I have also heard that deleting the array would make me lose all my data, I was looking for a way around that. If I remove the second drive like Louis suggested, before I take out the card or delete the array, it cannot lose the data off of the drive that is no longer connected and I should be able install it as a slave and still have all the data intact, just in case I forgot to back up something that is needed and can always format it later. You might want to consider doing it this way just in case you need something off of the disk.
He also said this 'When I played with my RAID setup, it was pretty simple. I went into the Promise BIOS, elected the boot drive, elected the array, it was done. When I had tired of playing, I just went in, removed the RAID, and left the drives reflected in the BIOS (as they should be because they are using the controller card)."
Maybe I am misinterpretting what he said there, but I thought it seemed like doing it that way, did not cause data loss, but I can't be certain as he did not say.
I do not know what kind of RAID controller you have and if it is not a Promise controller, it might work differently for you and the sata hard drives you have might make a difference too. I just thought I would share the good advice Louis gave me here in case it would help you too.
Why do you recommend using optical instead of flash drives for backups?
I use to use them but now mostly just use flash drives (I usually back up the same things on several of them) since they hold so much more. If I were to reformat, I would probably back up the most important stuff on CD too, but there a lot that I can't really put on them. I do however have a third harddrive installed and most of my stuff is also backed up on that and it is not part of the RAID setup.
Hmmm, in looking for an article on RAID for you, I just read something that leads me to believe that I cannot be running a RAID 1+0 even though device manager tells me I am. What I read says that you need a minimum of 4 hard drives for that and I do not believe I have that many. There is no way my tower could hold 5 drives and I was told there were 2. Besides, I think the tech would have mentioned that there were already 4 drives when he put in my third drive after I got this computer. I must just be running a RAID 1 even though device manager says 1+0 under disks, although I have no idea why it would say that. I know it doesn't really matter but I wanted to clear up what would appear to be an inaccuracy in my post
