thedoomguy Posted October 15, 2021 Share Posted October 15, 2021 A few weeks ago disk 18 in my array was disabled. I bought a new Seagate Ironwolf 8TB drive from Amazon, replaced the drive and let it rebuild. It rebuilt successfully but shortly after disk 18 became disabled again. I got a second replacement Seagate Ironwolf 8TB and had the same result -- rebuilt successfully but within a day disk 18 became disabled again. I tried re-adding the same drive (the second replacement) a second time and same result. This time though it was at least a few days before it became disabled again. That brings us today, I still have disk 18 disabled. I have a Norco 4224 with 24 drives in the array. 22 data and 2 parity. Diagnostics zip attached -- haven't rebooted since the latest incident of disk 18 being disabled. I would be grateful for any assistance and am happy to provide any additional requested info. bm-nas-unraid-diagnostics-20211014-2301.zip Quote Link to comment
trurl Posted October 15, 2021 Share Posted October 15, 2021 Haven't looked at diagnostics yet. My guess is there was never anything wrong with the original disk or this one. Bad connections or controller issues are much more common than bad disks. 55 minutes ago, thedoomguy said: Ironwolf Quote Link to comment
thedoomguy Posted October 19, 2021 Author Share Posted October 19, 2021 Hi, I followed the steps in the post linked above and disabled both EPC and Low Current Spinup on the second replacement drive for disk 18. The array rebuilt successfully then about a day later, disk 18 became disabled yet again. Quote Link to comment
