Hey everyone, here's a breakdown of a RAID issue I encountered on my work-from-home PC, along with the steps I've taken to address it:

• How I Discovered the Problem: Yesterday, a family member asked when I'd installed a new hard drive on my PC. That prompted me to check the storage setup, and I was surprised to find my original dual-disk RAID1 array had been converted into two separate, independent disks.
• Critical First Step: To avoid any risk of data loss, I immediately backed up all data from both disks to an external hard drive.
• Intel Rapid Storage Technology (IRST) Diagnosis: I opened the IRST tool to troubleshoot, and confirmed the original RAID volume was no longer present. What's more, the tool couldn't even detect either of the two disks that were part of the RAID1 array—so I had no option to rebuild the volume through IRST.
• BIOS Level Check: I also accessed the Intel RAID settings in my PC's BIOS, and the result was the same: the disks weren't recognized here either, leaving me unable to attempt a RAID rebuild at the firmware level.
