Dell Intel Raid 0 failure

#1 Post by NeedsMoreRGB »

My system specs are an i7-6700 running on a Dell workstation motherboard with 4x sata ports and 1 nvme. I have 4 250GB SSDs in a raid 0. I recently needed to perform some system maintenance (clone my nvme boot disk) which required me to boot into the bios and flip from Intel RST (Intel RAID) to AHCI. This was required as clonezilla did not recognize the nvme disk with RST enabled. After cloning and swapping the nvme disks I placed the system back into RST mode prior to ever booting back to windows. On my first boot, my raid 0 "disk" / "G" partition were no where to be found. Upon another reboot, this time into the Intel RAID utility, I found that one of the disks had been marked as a non-RAID member.

I then came across your software from this forum post: (https://www.overclock.net/threads/howto ... 57/page-15) and followed along as best I could along with the testdisk.pdf. After a quick search this partition structure was returned.

Previously, there was no true boot sector on this array, it served the purpose as a secondary drive for Games and VMs (which is where I believe all the other partition structures show up). There was a single large NTFS partition on that RAID array prior to the issues occurring.

My guess was I needed both the "Dell Utility" and "Game Drive" partitions for the recovery. I verified I can see files / directories in the "Game Drive" partition. When I try to mark both "Dell Utility" and "Game Drive" as 'Primary' I get a "Structure Bad" error.

So, if "Game Drive" contains all the data that I care about, should I only try to recovery that partition, or do I need to do something with the "Dell Utility" partition as well? Any suggestions are appreciated!!

The partitions Dell Utility and GameDrive are overlapping. You cannot set them to primary status simultaneously. Use the "p"-key ("list files") to see if the "Dell Utility" folder contains valid content at all.

So, if "Game Drive" contains all the data that I care about, should I only try to recovery that partition, or do I need to do something with the "Dell Utility" partition as well? Any suggestions are appreciated!!
You can either copy everything out of the "Game Drive" partition or set the "Game Drive" partition to primary status and write the partition table afterwards.

After verifying that I could read files from that partition (again) I marked the Game Drive partition as primary and I'm now back up and running! Thank you for your help!
