Before i shut down the system i was able to capture the attached System diagnostics and SMART log. The S.M.A.R.T report is for DISK3 which is currently "disabled/contents emulated".. I was not able to get anything for disk4. Thanks! tower-diagnostics-20220928-1952.zip tower-smart-20220926-1319.zip

Hi all, a couple of weeks ago I started hearing clicking sounds from my server but in hindsight didn't react quickly enough. When i logged into my tower I had a flood of disk error notifications Specifically, Disk 3 was disabled and contents emulated. When i look at the S.M.A.R.T summary it shows "FAILING NOW" and indicates that bad sectors have been reallocated for this disk3. I thought the clicking sound was this "disk3" hard drive. A couple of days ago i login again now to see my logs flooded with errors for Disk 4. My disks were all spun down (disk 3 still disabled but contents emulated), and a red x next to disk 3 and 4. The logs shows disk 4 errors but i cannot pull any S.M.A.R.T information or acces the disk at all. I stopped the array and shut down the server to look at the hardware. When i open up my tower i confirmed the clicking is actually coming from disk 4. This disk4 i have confirmed now is dead. No matter what i do Unraid will not recognize this disk 4 and will not allow me to start the array. It just says "missing" next to disk 4. It doesn't appear in the drop down menu for me to select even. In terms of what caused both drives to fail i will assume it's a power surge issue as i am not connected to a power surge protector and we have had outages this summer. So now i would love your help in how i can move forward. I have 1 parity drive and 5 data drives (now only 3 good ones apparently). How can i replace these disks and rebuild the array. Is the data on Disk 3 (disabled but contents emulated) still recoverable? I've cut my losses for disk4. My thinking is that I replace the dead drive (disk 4) and see if i can rebuild the array with what's remaining on the other disks. I am scared though as disk 3 is already disabled with bad sectors so i'm not even sure if it will let me. I feel like i've lost 2 drives worth of data here. Would really appreciate your help and guidance on how to proceed with this! Current Disk Setup attached for your consideration.
