Switched SATA ports now my RAID1 says Plex Missing, Redundancy Failed...now What?

Ok so like the posting says I had a perfectly good RAID1 software setup (W8Pro) using two WD Blue 1Tb HDD's. I opened the case up because I wanted to switch it to a hardware RAID1 and in the tutorial I was using it said to switch them over to SATA ports 4 and 5. After doing this and firing up my system and opening disk management it says "Failed Redundancy" on both drives and when I attempt to reactivate either drive it tells me "Plex is Missing". In addition to this another drive is showing up as failed which I used solely as a backup drive for my OS that contained a system image. I am unsure of what I did that would cause this or how to fix it. Worse comes to worse I wouldn't mind going back to the software RAID if it worked like before but anyway... Also as an aside my disk usage before was 33% on one and 66% on another is this normal for a RAID1? It was always a combined 100% (~99%). Does anyone know what I should do from this point to get back to a working RAID1? FYI I can access my files on the drive path (for what it's worth M: ) perfectly so I don't think there is anything physically wrong with the HDD's it seems like more of a BIOS or something issue. Please help I am a relative newb to building my own computer and this is my second system.

Rig: Intel i7-3770k, MSI Z77A-GD55, MSI GTX 760 OC TF, 8Gb G. Skill 1600Mhz, SanDisk Extreme 120Gb SSD, 2xWestern Digital Blue 1Tb.

  1. put everything back to the way it was.
    Software raid1 is fine and no different than motherbd raid1
  2. ok i see your point and that is what i was fine doing but now i have a second issue and that is i am not really sure what SATA ports i had each drive hooked up to originally so now what? im certain my SSD was on port 1 which is the SATA 3 but otherwise i really cannot remember what was what. also why wouldn't my other backup drive show up at all since i moved them around? so say i cant recall the previous setup what is the best way to go at this? should i break the mirror? backup my files to an external and do it fresh? why wont it just recognize the drives? my HWMonitor application shows all the drives in the correct ports so why cant windows 8 do the same since it is a software RAID? anyone have any of the answers to these questions? thanks for all the help.

    First I would try to reactivate the mirror, if that fails or isn't available I would backup the data you have, break the raid and then immediately recreate it. I can't recall if win8 needs the mirror drive to be empty first or not but thats easy to do if its needs it.

    BTW you should always be making backups of stuff you don't want to lose esp when you are about to mess with them. A mirrored drive is not a backup.

    To reactivate the drive, in disk management right click on the drive that says missing (or offline) and then left click on reactivate.
  4. thanks a lot for your help. i am going to backup my files and then break the mirror and format both drives before reestablishing my RAID1. at this time should i go ahead for a hardware raid since i now have to start over anyway? does it matter or not really? the main reason i wanted to do the hardware raid1 was to be able to access it from a linux distro as well as windows 8 pro. i am a relative new computer tinkerer but since building this rig i have been trying to get it set up the best way possible so i dont have to constantly open up my case to move things around. i dont have a large amount of files at the moment after my 950Gb worth of storage failed on me right before i purchased my second (then third HDD). thanks again for all your help. much appreciated.
  5. Ok now thats a valid reason for the chipset raid1.
    Theres no need to format either drive or switch sata ports first. I leave the 6g sata ports open for ssd's and use the lowest numbers sata 3g ports for hdd.s Optical drives go on the highest numbered sata 3g ports. (sata 3g = sata2)

    Just enable raid in the bios, reboot into the intel raid bios by pressing ctrl +I when prompted and setup the raid from there. You can format from there if its doesnt happen automatically.
