April 9, 201016 yr So if you're paranoid, just do it I guess. So if being called paranoid is the alternative to being called stupid, I'd rather be called paranoid I guess. For most of us with home servers, there are not the time-pressures that exist in the commercial world. We can take an additional day to pre-clear a disk. It is not paranoid, or stupid, but cautious . As I said, burning in a drive is never necessary... reducing the off-line-time of your home media server is not necessary... But if you have the luxury of being able to pre-clear/test/exercise the disk before adding it to the array, recommended.
April 9, 201016 yr Author The general consensus seems to be that I should run a preclear, so since nothing is time sensitive I will. Here is where I am at now I have not yet formatted the disks and have downloaded the preclear_disk.sh from your main post Joe L. Hopefully I can figure this out by reading your preclear post, but I just wanted to make sure I was on the right track before I moved on. Thanks to everyone who has been of such great assistance here.
April 9, 201016 yr I tend to preclear less to see if the disk is DOA or has other problems (though this is a useful side effect) but more to just allow the array to be online available during the preclearing. If left to unraid the array (I believe) has to be stopped during this process which isn't very convenient. Once precleared it's a matter of seconds to stop the array, assign the precleared disk and start the array again. Minimal array downtime.

Thanks to everyone who has been of such great assistance here. You will need to un-assign the disks from your array before running the pre-clear script on them. It is coded that way to prevent you from accidentally clearing a drive that is already part of your array, and holding your precious data. Joe L.
April 9, 201016 yr I like how you've blurred out your hard drive serial numbers. There is certainly nothing wrong with that, but just to let you know, it is unnecessary. There is nothing malicious that any of us can do with those numbers. We cannot steal your data, or your unRAID license (if you had one).
April 9, 201016 yr I like how you've blurred out your hard drive serial numbers. If you give it some thought, you'll discover that "3560freak" decyphers as "Blur Freak". Speaking of blur... I see you blurred your avatar!? And I was just about to steal something from that disk darnit!
April 9, 201016 yr If you give it some thought, you'll discover that "3560freak" decyphers as "Blur Freak". Not following you here.... Speaking of blur... I see you blurred your avatar!? And I was just about to steal something from that disk darnit! That's not blur, that's a halo! My disks are divine. By the way, the disk in my avatar is a 2 yottabyte disk from the future, and it contains the entire internet. It is therefore 87% porn.
April 9, 201016 yr the disk in my avatar is a 2 yottabyte disk from the future, and it contains the entire internet. It is therefore 87% porn. LOL that's a good one Rajahal !! You should put that below the avatar!
April 9, 201016 yr Meh, function over form. I like the motherboard rating system, I know I used it a lot when initially looking for a motherboard for my system. I'll leave the comment buried in this thread for future internet archaeologists to unearth. They are already underway: Internet Archaeologists Find Ruins of Friendster (that link is blocked by my work firewall, so I hope it works for you...) By the way, you should add your motherboard to your profile using the Motherboard Rating System.

I used to be a part of a cell phone forum and giving out ESN/IMEI numbers could lead to potential abuse (cloning, etc) so it was always blurred out.

April 14, 201016 yr Author should I be worried? I just precleared all disks and no really errors showed, but after formatting the disks the console shows 182 errors on disk 2.
April 14, 201016 yr Get a new smart report on that disk. It might be the disk, it might be the cabling to it. Post a syslog. It might have clues as to the nature of the errors. Joe L.

April 14, 201016 yr Author so since these are blank drives, I guess there is nothing to worry about. Thank you Joe L for all of your tremendous assistance
April 14, 201016 yr so since these are blank drives, I guess there is nothing to worry about. Thank you Joe L for all of your tremendous assistance Since it already has pending sectors I would return it for a replacement if this is a new drive. There should not be any at all on a new drive.
April 14, 201016 yr Since it already has pending sectors I would return it for a replacement if this is a new drive. There should not be any at all on a new drive. I would RMA it too. It's new. There should be 0. My 9 month old WD's with nearly 6400 power on hours have -0- reallocated events and current pending sector.
April 14, 201016 yr Author does anyone know how strict Fry's Electronics is on returning drives for this reason? Since they are not technically supposed to be RAID class drives will they hassle me?
April 14, 201016 yr Dont mention raid at all. How unRAID uses the drives is more like typical desktop use. Mention that you ran a SMART test which indicated it had failing sectors. You might also want to run a long smart test too and see how bad the issue is.
April 14, 201016 yr does anyone know how strict Fry's Electronics is on returning drives for this reason? Since they are not technically supposed to be RAID class drives will they hassle me? Why in the world would you tell them you were returning it because of unraid issues? It has nothing to do with unraid. The pending sectors are reported from the firmware built into the drive its self. Is this the first time you have ever returned something to the store. When returning something it is best to only state the actual cause for the return as simple and as clear as possible. Saying anything about issues that have nothing to do with it will just confuse them and they may just end up giving you store credit only. Though, you probably just want an exchange, which should be no problem if you simply tell them this drive is defective and you would like a new one.
April 15, 201016 yr Author I guess it only gets worse. Here is what I've got today. I guess the drive is going back
April 15, 201016 yr The fact that the drive is showing as "red" indicates that a write to it failed. Unless a cable is loose, you should RMA that thing and stop pulling your hair out over it.
April 15, 201016 yr Yeah, get an RMA for it, and get yourself a replacement disk. From the read of this thread you've had a bit of bad luck with this disk.
