Split Raid 1, can't access data on the separated drives

Hi everyone,

I'd like to start by saying that I've read the rules and that I've googled my problem for a while before posting here. The topics I found there were not exactly my problem, and not specific enough, although my problem seems fairly simple :

I was running two 1TB HDDs in RAID 1 on my desktop, running an AMD CPU on an Asus TUF X470-PLUS GAMING motherboard. I was using the RAID mode of that motherboard, that's also what I previously used to build the array.

I then thought (based on google) that I could just separate my drives into different computers and that it would work, they'd be recognized by Windows (in AHCI mode). Well, it doesn't, and I also tried running Ubuntu on a thumb stick and my drive is not showing up aswell.

The drive shows up in Disk Management, with a partition shown as healthy. I can't assign a letter to the drive by right clicking. I'm a bit worried to use data recovery software, because I'd like to make sure that my folder structure will be kept, since there's quite a lot of data in there.

For personal reasons, it would be a bit complicated to reunite the drives into the motherboard and backup the data. But if you guys tell me that it's my only option, I guess I'll find a way. It just sounds stupid that I can't access my data even though I know it's right there, on a healthy partition.

Thanks a lot in advance for the help!

Cause they were in RAID 1, the partition spanned both drives. The first drive will have the start of the partition but no end and the second will have the end of the partition but no start. Therefore, the whole partition can't be recognised unless both drives are plugged into the same machine.

 

Crossing this out as I'm not sure this was correct.

Common build advice: 1) Buy the cheapest (well reviewed) motherboard that has the features you need. Paying more typically only gets you features you won’t use. 2) only get as much RAM as you need, getting more won’t (typically) make your PC faster. 3) While I recommend getting an NVMe drive, you don’t need to splurge for an expensive drive with DRam cache, DRamless drives are fine for gamers. 4) paying for looks is fine, just don’t break the bank. 5) Tower coolers are usually good enough, unless you go top tier Intel or plan on OCing. 6) OCing is a dead meme, you probably shouldn’t bother. 7) "Bottlenecks" rarely matter and "Future-proofing" is a myth. 8) AIOs don't noticably improve performance past 240mm.

You know Raid 1 is mirrored, right ?

I don't know your answer, but I googled "break raid 1" and I get answers.

Did you try that ?

 

How did you make that mistake ? When you disassembled the drive, you just had to start the computer and confirm it runs ok.

Yes, I'm aware the Data is mirrored, but I was under the impression that the partition info or disk header info wasn't (depending on the raid controller used). However, upon checking further, that might have been incorrect. Not sure.

 

Either way, with further reading what I did find was this, which seems to point to the same overall answer of "you need to put them back together":

Since it's RAID1 one should be enough, but it'll have to be on the same type of RAID controller.

 

I've moved Intel mobo RAID sets between several mobos without issues, but they have to be on an Intel mobo with RAID support to work, a direct disk won't be readable without the underlying support.

 

I believe things like testdisk can modify the headers to make the partition readable directly, but I wouldn't mess with that if there is any possibility of using the intended setup.

The drive shows up in Disk Management, with a partition shown as healthy. I can't assign a letter to the drive by right clicking.

Give us a screenshot of it. 
 

Is it dynamic?

Thanks a lot for the help guys. Holy crap, I fixed it, I'm so happy.

Context for those with the same problem :
- I gave up the idea of trying to recover the data as I didn't want to mess up the RAID configuration, since both drives were functional (just separated)
- However, I discovered that my current motherboard is not the same one as the one I used to create the RAID1 array. In the old one, I used the RAID configuration menu (that you access with CTRL+R on boot), and on my new Asus X470, it works with the RaidXpert2 software + the AMD RAID Software.
- Just plugging both drives and booting in RAID mode didn't work. But after installing the RAID drivers from the manufacturer's website, my drive magically appeared in Windows!!

Thanks so much and have a lovely day!

But again is it dynamic? 
 

I once tested software raid from disk management in windows ( the mirror mode ) it creates dynamic disks, but you cannot access them separately, without disabling the mirror in disk management.

It's mobo "hardware" RAID, this doesn't apply.
