Attached is a syslog I just collected. I swapped SATA cables as well and am still seeing the same errors. syslog.txt

I just purchased 2x WD20EARS drives from Amazon. When I received them, I immediately jumpered 7-8 prior to installing into my unRaid. I tried putting 1 drive in as my new parity drive, replacing a 500GB that I previously had in there as parity. Everything seemed to boot ok and unRaid recognized it, but when it did the re-build of the parity after hitting Start, that's when I seem to be having problems. It was poking along at something ridiculous like 20k/sec and would have taken 3 months (this is probably an exaggeration) to complete. When checking the syslog, I'm getting absurd amounts of this message: Dec 5 15:36:14 media kernel: ata3: drained 32768 bytes to clear DRQ.

I'm seeing it take insane amounts of time during the pre-read. I let it run for 36 hours and it ended up getting to 1%, completing around 30gb out of 2tb. I ended up canceling the pre-clear and trying my second drive. Same exact thing on both. I've attached the SMART log that was run prior to the pre-read. It isn't reporting any re-allocated sectors, so I'm not really sure what is going on. From what I've read, the pre-read shouldn't be taking 36 hours to reach 1%. I never ran these drives un-jumpered. They were immediately jumpered out of the box (thanks to reading these forums), then installed into my unRaid. My hardware specs on the system: AMD 2800+ Gigabyte GA-7N400 1.5gb DDR2 RAM 2x 2-port PCI SATA card - different brands. I can't really see what the exact model they are, as they're currently installed. I don't think it's a bad cable/card, as my previous parity drive ran just fine on the same port, but who knows. Can anyone shed some light on what may be happening? I'm thinking I received a set of bad drives, but since I didn't see any re-allocated sectors on the SMART report, I'm not really sure. Thanks in advance for any help! smart_start1528.txt
