Please see pre-clear report below. Ironwolf 4 TB, ~ 3 years. I was using them with a NAS box then recently built a DIY one w/ HP Elitedesk from 2020 I think. Previous NAS never reported any errors. The new setup has been running for ~ 1 month. All a sudden unRAID starts showing read errors. I looked on the forum and decided to do a pre-clear and see how it goes. Preclear "successful" but Reallocated_Sector_Ct and Reported_Uncorrect increased w/ preclear. Is this likely a disk or MB issue? If disk, can the disk still be used given preclear successful or is it RIP/RMA? Thanks so much for your input!!
