Okay, ran into a problem and I've been doing a lot of reading on solutions for recovery.

Situation: Desktop blue screened and drive was unrecoverable- system down so I basically said it was God's way of telling me it was time to do a clean install and enjoy the fresh new car smell with a fast system.

Turns out it started with a thread error and went downhill from there. At first I thought it was the GTX 970 but in the end it looks like it was the Creative Labs Sound Blaster Z card. Something you gus already know but bears repeating. Reinstall one at a time so you can try and determine where the point of failure is.

On to the problem. I had two internal WD Black drives setup as RAID 0 through the ASUS Bios utility. The drive showed up in explorer but couldn't be accessed saying it needed to be formatted.
Back into the bios and I could only see one of the drives.

So my question is has anyone used the ASUS BIOS EZ Tune to repair their RAID? The drives are now showing in BIOS and I did try and set them back to RAID to "redirect" them again but when I did that my Samsung 950's went offline and I had to setup Windows to an old drive to get back into the system.

I'm a photographer and this RAID holds all of my working stuff. I haven't backed up since November so I'm trying to not lose what's on there. I have the Testdsk and Photo Rec programs but my gut tells me its as simple as recreating the proper path.

Any help you can provide utilizing the ASUS Bios would be great.

Appreciate the groups input as always!

An update if anyone is interested.

Now that I could finally see my Raid drives, I ran TestDsk and it found all of my files on the drives. That's the good news.

I can pay $79 for the SW license and download them is one option. The other is I can find a solution so that my desktop recognizes the Raid and used normally.

Ok this sucks, first, in your BIOS do you see both drives? if not the answer is your data is gone. the way RAID 0 works is that it stripes the data, and we are not talking about "one program on that drive and one on this drive" we are talking on bit level. so a single file/program could be chopped up into 1,000's of chunks and written to both drives alternating. So you end up with a pile of data goo if you lose 1. For future reference I would use a RAID 1 or a RAID 5 with 3+ drives.

So the good news is I can see both drives in the Bios I just can't access them in Windows before I do anything stupid I wanted to check to see if anyone had experience with Asus Bios since they are all different.

The Raid 0 was a working drive not a backup drive. It's just that I hadn't run a recent backup from it and don't want to lose any recent stuff.

Totally my fault

The next question is, was it a hardware raid or software? when booting the PC do you see something like "hit CTRL+R to go into your raid menu?"

No, not hardware as in a specifically built Raid. It's is two same drives that I created a Raid out of in the Asus bios setup so I think it uses Intels SW Raid solution

eww... ok. if you make a raid in the future you are better off using a hardware raid.

Yeah, I did read that but figured since it was really a working drive, whats the worst that could happen? My issue was I hadn't backed up in too long.

Here's some additional info from the bios that may help.

Under the Advanced tab:
HDD/SSD Smart Info- Both WDC drives show and both have activity

Advanced\PCH Storage Configuration--> SATA Mode Selection--> Set to AHCI (instead of Intel RST Premium RAID)

(Side note: all drives are setup SATA except for the two Samsung 950 M.2's which are my boot drive and scratch drive)

The RAID drives in question are listed and enabled as my SATA 6G_3 and SATA6G_4 drives both with hot plug disabled.

When I tried to enable Raid through the EX Tuning Wizard my M.2's disappeared.

Again, not sure where to go from here but I feel like it's something fairly simple in that I need my system to reacquire the drives.

Thanks again everyone-

I would not change the disks to AHCI from the RST raid. you mentioned your OS was on a SSD, can you still boot into the OS?

Yeah they are on AHCI. When I had to reinstall op sys and updated BIOS they went back.

I created a new boot drive from a spare I had because the SSD's weren't recognized without the NVMe drivers. The SSD's (boot) are back up and are running fine. The only missing piece is getting those two disks to read Raid 0 as they did before. If I can see them I'll pull everything off and then plug the holes in my workflow so if it happens again, I'll only lose the days work.

I read that to get into the Intel RST you need to hit CTRL+Shift+I (or something close) but I tired and couldn't boot into it. That left me the conclusion that the Asus bios EZ Wizard must be the primary point on the raid setup. I'll give it another shot though.

In the EZ wizard you have two options.
1) Do you want to boot from USB
2) Do you want to create a Raid (if doing so all data will be lost)
It then reboots into bios and your drives are setup in raid where you set the config.

So this is where I was when it started. I created the raid as the steps said it really just erases the meta and not the data- They got created but I couldn't boot at that point as it wiped the link to my SSD's. I have those back now but am now back out of Raid. Feel like I'm chasing my tail!

so your drives are set to intel RST raid again correct? it would be required for you to be able to get into the management for it. as for the asus bios utility, i think if you use it all it would do is break things.

My apologies. The drives are all set to ACHI. The other option in the dropdown is Intel RST. I didn't want to enable RST until I had some confidence that it wouldn't blow things up again. I guess I can always unhook the two M.2's and leave that old boot drive there and see what happens?

why your SSD's are not showing up is due to you have to create them as a virtual disk in the intel RST raid controller. I hope your raid 0 disk's still have their raid configuration written to the drives. do not initialize or delete foreign configuration on any disks. Sorry Brochacho, if you lived near by i could help but it's difficult to troubleshoot over a forum :)
