August 30, 20214 yr Still in my trial period. I have 3 10TB drive a WD purple which I set for parity and 2 identitcal drives. All are connected to a dedicated sata 3 controller. I see all 3 in the tools - hardware [7:0:0:0]disk ATA WDC WD102PURZ-85 0A82 /dev/sdb 10.0TB [8:0:0:0]disk ATA OOS10000G OOS1 /dev/sdc 10.0TB [10:0:0:0]disk ATA OOS10000G OOS1 /dev/sdd 10.0TB But only 1 of the bottom 2 drive appears in the array configuration and I cannot figure out why?
August 30, 20214 yr Community Expert Go to Tools - Diagnostics and attach the complete Diagnostics ZIP file to your NEXT post in this thread.
August 30, 20214 yr Community Expert Where did you get these? They don't appear to have unique serial numbers. Each disk is identified by its serial number so Unraid can't keep track of them separately.
August 30, 20214 yr Author Ah the joy of ebay drives... yeah I see a few other folks out there with this issue now that I know what to look for. Is there any way of artificially setting the serial number? One of the other threads suggested "For me the solution was to enable "list IOMMU" in the motherboard BIOS." so I will check that as well.
