Data corrupted on RAID 1 array after booting in IDE mode

I am running a Windows 7 64bit system that is on a separate hard drive than my RAID array. I have two Seagate Barracuda 2TBs that are currently in a RAID 1 array. I also have a fourth hard drive that is running an unused Windows 7 that I had installed previously, only that OS was installed when my computer was set to IDE, not RAID like it is now.

Recently I switched the mode to IDE instead of RAID in order to boot from my other hard drive which had a couple of programs on it that I wanted to use. After a couple of days (and a couple of reboots) I switched back to RAID mode and thought I was all set. Every reboot since automatically goes to the chkdsk tool and wants to try to fix the drive. I went through one fix-it time and it said everything was good.

Now what I'm getting is that several of my folders are listing that they are quote "M/... is not accessible. The file or directory is corrupted and unreadable." I tried rebooting a couple of times and got the same chkdsk tool. I went through it a couple of times and ended up stopping it abruptly (probably stupid idea), but nothing seemed to change. Still getting the same corrupted message. Weird thing is is that the folders that have the problem will suddenly not show that message anymore when I click on them, and instead others will have that problem.

So I have a couple questions about this. First of all, did I lose everything? This data is important to me and I don't want to lose it! Secondly, If there is a way to make those messages go away and restore my data to the way it used to be, then can that way involve software that is already on my computer, rather than a third-party program. I know now not to use the chkdsk tool for RAID arrays, wish I had known that earlier... And I also know that switching to IDE mode caused all this. Dumb mistake.

Any help would be greatly appreciated!
Thanks

important data should always e backed up and no form of raid is a backup.

With that out of the way, I believe you will be able to recover your files using recovery software. raid 1 saves you from needing specialize software and the normal pc stuff should work. Try recuva, thou I would start with testdisk and see if the partition can be recovered.

be sure to have a drive/space available to recover to! You do not recover back to the same drive you are trying to recover from. that might write over the top of things not recovered yet.

popatim - Thanks! I know now RAID is not a good backup. And yes I have another drive that I can recover these files to. Heres the thing, now I'm looking at it and its showing only a few folders (some are subfolders many levels down) have corrupted files. Is this something I should still use recuva for?
