Something of a layered problem here, so I hope I'm in the right place.

Current issue: BIOS will not load. Splash screen shows up, but hitting Del does nothing. Considering resetting CMOS to solve? But I'm concerned with conflicts with my main issue, below.

Main issue: I have a Raid-5 in my system that has gone down. I belive I caused this when tinkering in the BIOS to fix a different issue I was having. In my haste to solve the problem, I toggled RAID mode off on the chipset controller. Now, the raid bios loading screen says the raid is not detected, even after putting it back in Raid mode. Im worried that I may have caused it to lose the raid when I switched that mode off briefly??

Windows seems to see it... Sort of. It wants me to format the volume, but it does seem to still read it at the full ~8TB that it should be (left over information??). If I load the raid bios I do have the option to create the raid again, but I cannot risk losing *any* of the data on this raid.


Motherboard is a gigabyte X79-UP4

Sorry for poor formatting; currently on my phone.

Any advice would be welcome, and I will clarify absolutely anything that needs it. This has been a ridiculous series of problems, but now I'm just panicking about the potential data loss.

What CPU ? What bios? What HDD or SSD do u have ?

All X79 2011 mobos seems to have too small bios chip for new
4820 and 4930 cpu bios. Maybe this is related to that?
My UD3 is working with old bios fine but if I upgrade the bios to new one then gigabyte says that the bios chip is too small to work with 3D bios. My suggestion is build NAS. Thats what I did and hope it works better like this. No HDD in system anymore and just fast SSDs in desktop. Then nas do have RAID and all what needs to be safe.

This comes handy if windows or any other thing goes wrong. New windows takes just 3min to install from usb. 10min and I have all new drivers and stuff I need.

Id try in this issue fix that RAID by just taking it to use by...

Hope this helps :)

Thanks for the reply. I will take your suggestion of using a NAS setup in the future, but that doesn't really address my immediate problem of recovering the existing RAID and (more importantly) the data it contains. I probably should have been more specific. Specific questions below:

- Would resetting the CMOS potentially damage the RAID controller's settings under normal circumstances (i.e. RAID-5 is fully functioning but I reset the CMOS anyway. Does this cause errors in the RAID controller and/or require the raid array to be re-created in the raid configuration BIOS)?

- Assuming my issue with loading the BIOS configuration settings does not exist (i.e. all other circumstances are ideal, aside from the fact that I toggled RAID mode on the controller off and on again and can no longer load the raid properly), how should I go about repairing/re-discovering the RAID, and/or how would I go about recovering my data if this is not an option?

Please help! This issue is crucial to my business and I'm panicking.

Click to expand...

Is bios still RAID or did it go to AHCPI mode? Or HDD
There was two place in bios that needs to put raid mode before itwork to me when I did RAID 0 with SSDs

But maybe this is not same issue.

Are you using Intel or marvell raid? Did you load raid drivers too? Just do this like you did when you istalled it. Just do not format the raid. volume. (if this is possible)

Okay, so I've dealt with this issue now. Thanks for all the help!

In the end, all I really did was get the program Restorer, which let me create a "virtual RAID-5" out of the disks that had been on the RAID array originally. I scanned and recovered everything that I could (took about 48 hours, and I wasn't able to get 100% of everything). Then I rebuilt the array from scratch and recopied over. I had hoped to bring the raid back online, but there was no way that was going to happen.
