March 13, 20251 yr Hello I've been seeing these in the logs for a while but never cared to look it up. But now I'm very curious as far as I know I don't have anything on ATA4.00. Some insight from someone? Running pure ZFS pools, 7.0.

March 14, 20251 yr Community Expert 10 hours ago, Nischi said: I don't have anything on ATA4.00 It's the SPCC SSD, try replacing its cables.
March 14, 20251 yr Author Solution How did you figure that out? I usually look under tools, system devices. But couldn't find any ATA4
March 16, 20251 yr Author Just a follow-up. I did change the slot for the SPCC SSD, and the error appeared again(this time as ATA1). I'm guessing it's a problem with the drive, altough it its fairly new and unused. A bug I also noticed is that it always shows 40c temperature, regardless of the real temp. Will probably retire it in the near future.
