I attached the drive to SATA port 3 on the motherboard (removing data drive already attached there), and started a PreClear, for 2 cycles (this was early Monday morning, around 5 am). It finished successfully this morning about 3, so it seems the drive is fine, and the add-on controller is not. Thanks to you and Omid for pointing me towards that. The storage controller I'd been attempting to use has only 2 ports, one of which is in use and has been working fine, but I need a port in which to connect the data drive I removed from motherboard SATA 3. Is it safe to assume I should expect the same problems if I tried plugging the data drive into that second port, and should just purchase a new controller? Also, what's an HBA (I'm still quite ignorant with much of the terminology, etc)?

Sorry, didn't think about the diagnostics log; it's attached. The problem drive is SMR apparently (Model Family: Western Digital Red (SMR)). I had tried switching cables a number of times on the first one, but haven't yet tried on this one. The drive is attached to a 2 port storage controller a co-worker had given me. I'm not sure of the make/model. I haven't tried plugging the new drive into the other port, which is in use; I'll do that, but, if it works, and it's a port issue, it leaves me without the other drive - not the worst outcome, I guess. Are there any plug-ins that you know of that are similar to HWiNFO for Windows that can give me a detailed view of the hardware in my box? cntfile-diagnostics-20210418-1624.zip

I'm running Preclear as a confidence check on a new 4 TB Western Digital (Red). It's failing, and, as this is the second brand new 4TB WD drive it has failed on, I'm unsure as to whether it's the drive or the plug-in. Full disclosure: I'm not an UNRAID power user; I obtained it strictly to turn an old PC of mine into a file server; for which it's been working fine. This is my first attempt at adding a new drive; I planned on the 4TB becoming my new parity drive and using the 2 TB it replaces for data. I'm attaching the Preclear log. Let me know if I'm just unlucky in having purchased 2 bad drives in a row, or if there's something that can be done to get this newest drive working. Thanks in advance for any help. preclear_disk_WD-WX42D8058N2A_11243.txt
