RAID 0 crashed, but more importantly, why did this happen?

post #1 of 6
Thread Starter 
I shut down my PC, and when I came back, it was running and not recognizing my 2x2TB RAID 0 array. Over a year ago, on my EVGA X58 FTW3 motherboard, I set up a RAID 0 on my SATA II controller. What makes a PC turn back on and destroy data? How much more info do you need to solve this, or is it too weird?

Have you checked Windows Disk Management?
Have you checked Device Manager?
Have you checked Windows Event Viewer?

Typically the cause is a cable failure.

If it's not a drive failure, take a look at this.

EDIT: Booting of your SSD without writing to the disks normally won't cause issues. Set your controller to AHCI, boot into Windows, do the above. (but don't do any writing, formatting etc to your hard drives)

Also: if one of your drives won't show up, you know what the issue is.

Yes, the hard drives are there. They're two unformatted 2TB drives with no info.

The computer does see the hard drive.

Ah, no, I forgot and now to go back might not help. I'll have a look soon, though.

I don't think a SATA cable failure would have turned my computer on, disabled the RAID controller, saved the BIOS setting, rebooted, and gotten into Windows to show both hard drives doing just fine. This would be a pretty cool ghost story if ghosts were real.


And xioros, I've been scanning to recover some data, but there's no info. That link leads me to a helpful site, and I hope others get their RAID 0 files back, but I just lost about 2.7TB of files and got two clean, file-less hard drives.

Mechanical drives without TLER or equivalent (https://en.wikipedia.org/wiki/Error_recovery_control) are often highly unreliable in RAID 0 and even minor system instability can exacerbate this.

Unless one or more of the drives actually failed, it should not be difficult to recover the data (many data recovery programs can scan for striped data, and if you rebuild the array exactly as it was before, the data should be intact and readable, with recovery software, as a standard volume, regardless), but I would recommend against making a RAID 0 your primary/OS drive.

The drives stored a lot of video editing things. I had finished all my projects, so I just lost all my raw footage. It's a shame, but I'm managing. I will keep trying to recover the data by scanning with whatever other stuff I can find. I think I've come across a FAT32 MBR, but I'm pretty sure it was NTFS...
