My computer crashed and when I restarted, the bios was wiped out so I had to restore from one of my previously working OC profile (MB is Asus P6T). But to my dismay, my HDD on port 2 is no longer part of my Raid 0 (comprising of HDD on port 2 and 3). In Intel Matrix Storage Manager, the 2nd drive is "Missing Hard Drive". I tried reconnecting the drive but it still shows up as a non-Raid.
According to SMART, the drive is fine. It's just somehow "disconnnected" from the Raid-0.
