First time poster here, Love the show. Matter of fact I am a Computer Information Technology instructor at a Collage and love showing the computer segments of your show to my class. They really liked the hard drive burrito. Anyway I just got a 6tb WD red drive of eBay with 41 bad sector and am currently running check disk on it. Has about 400 hours of run time and was made in Aug 2014.The sell acts like that it’s no big deal. WD Lifeguard quick smart test passed. Should I be worried? By the way WD warranty checker says it out….Here is the quota from the seller 

“HD the way it build always has extra 10% of hidden capacity, 600 gb. Table record all info from the build, 41 bad sector out of millions is nothing. As matter fact, those sector had been closed and replaced with extra sector. We bought these drives as a big bulks, S/N may not in their end user listed. If you have problem, you can claim for replacement. But you claim it as a gift because I am private seller, not their authorized dealer. They will base on manufacture date on label which Aug 2014 and send you replacement. Very easy, my customer told me about it and they prefer claim from them. Anyhow, your drive is fine. You won’t have any issue. We tested them every single tracks. “ 

Any thought or help would be helpful. Thanks and can’t wait for the next show.

First rule about my post, don’t talk about Quadcopters.

Wow that sounds super sketchy. While you could run SpinRite and probably be fine, I would look up the serial # on Western Digital's RMA page. If it's eligible for a RMA replacement, then do it. If it's not, but should be, then you might want to look into whether the eBay seller is running a scam to liquidate drives with errors from his own inventory.

If in doubt, you could run spinr.... Wait a minute!

41 probably isn't that big of a deal. I think I've heard that Red drives are designed to be used in a RAID configuration where more bad sectors isn't a big deal, so if 41 is a lot normally it may be by design here.

 

Also, as Jeff said it wouldn't hurt to check WD for warranty. They replaced my 2TB with a new 3TB and it was a month past warranty expiration.

If you haven't run a long test/detailed scan from the WD utility or other SMART-aware software, now would be the time.

 

smartmontools over at SourceForge provides a Windows version of smartctl, a very cool utility for reading SMART data from your hard drive. With this, you'll be able to get some data about how many sectors have been replaced, actual operation hours and a lot more.

 

The output isn't always easy to decipher and vendor specific. You'll also be able to trigger tests and read results of past tests.

 

Hopefully between the long test and operating hours, someone at WD will realize that the drive is too unstable for its age and replace it.

 

As many TWiT fans who follow Security Now will tell you, Steve Gibson (SpinRite's author and hard drive expert) has said many times that he stays away from the largest drives on the market. There's so much data crammed into such a small physical space that the only reason they work at all is because of multiple redundant error correction mechanisms.

 

It follows that drives on the leading edge, as far as drive capacities, may tend to have glitches or design flaws that show up more rapidly. This may be the case, with no malice intended by the seller.
