I'm using a Dell PowerEdge R820 with PERC H710 adapter
I had RAID 0 configured across two 1TB SSDs, Drive A and Drive B. I recently bought a 5TB HDD, Drive C. Today, I was attempting to create a RAID 0 volume for Drive C in the LifeCycle controller, using the "configure raid" option under the "Home" tab. I set up configuration for Drive C, and finalized the changes not realising that this overwrites my existing configuration for Drives A and B. Drives A and B contain(ed?) my OS, and on rebooting the server, no bootable devices were found. I looked in the BIOS but only saw Drive C configured for RAID. Then, I went into the RAID Controller BIOS and recreated the Virtual Disk for Drives A and B, without initialising them, which the BIOS told me would preserve the data on them. I set this new volume to be the boot volume, and rebooted, but I was met with the same message. Is my data gone?
