October 2, 201510 yr Author What is the current state of your array? Is the disk still being emulated? If so, you should forget about that disk and get your array back to normal by rebuilding, not copying, its contents onto a new drive. Then when things are working again you can try to determine if that disk is worth keeping. I was trying to copy of disk2, which was disabled in the array by unRAID, when disk9, which passed preclear twice starting acting weirdly. That's the smart report that I posted. I cannot rebuild with two bad drives.
October 2, 201510 yr Author It seems that this drive keeps producing errors. Can someone give me a hand with the SMART report? Bad sectors. Did you Preclear it before adding it to the array? Unfortunately that drive model (ST3000DM001) has the WORST reputation of all current drives! But they're also the cheapest per terabyte. You are probably going to have to remove the drive and Preclear it a couple more times. I just removed it and ran a Seatools on it on a Windows. It failed short generic test. However, the original failed disk2, SMART through unRAID console reported as passed. I can live with the lost disk9, as I have it backed up; however, is there away for me to re-add the disabled disk2 and retain it's information, and then rebuild parity without disk9? Can I somehow make unRAID trust the disk2?
