Here are my results from new hard disk. After preclearing i replaced a bad disk for this one. Rebuilding worked fine i guess (everthing green now). Is there a way to check if the rebuild is succeful, or can i just trust the green lights? syslog-2012-03-22-disk3new.txt

It indicates the second chipset is configured in your BIOS in Legacy mode where it is emulating an old IDE controller (IDE devices show as "hda, hdb,etc"). You should change the option in your BIOS to AHCI mode and get it out of legacy mode. Many BIOS have a setting for each of their disk controllers. The Legacy mode is enabled by default on many motherboards to allow them to boot older microsoft operating systems. Win-XP and prior have no SATA drivers, and therefore could not boot windows if the chipset was in SATA mode. This is not an issue with Linux or unRAID. All that said, either setting will work, and you can change the mode later with no effect or impact on your stored files. It is just that the emulated legacy mode is frequently slower, as it does not take advantage of the features available in modern drives. Joe L. I understand, i was already preclearing the disk but i'll set it to ahci after preclearing. Thanks

I just received my motherboard back from rma. Here's the thing: i've precleared 4 disks succesfully. Now when i add the fifth it's not sda, sdb etc. but hde, it's the same drive as the other ones...could it be that it's because port 5 and 6 are on a different chipset? Just asking because i don't want to start off the wrong foot.

But if the 100 current value would go below 051 it's an rma? I hope someone can clear this out for me so that i don't have to ask this anymore.

Finally, my first disk is done pre-clearing. Are my results any good? Can someone please look at the syslog. I have no idea whether it's good or bad. Sorry still learning... syslog-2010-29-11-disk4.txt syslog-2010-01-12-disk5.txt
