WD My Book extended test on WD Data Lifeguard showing 08 - Too many bad sectors

Hi all,

recently I purchased 3 WD Mybook 8TB from Costco for purposes of shucking them for NAS and when I ran through the extended test on 2 of them on the WD Data Lifeguard, they all ended up with 08 - Too many bad sectors.

I'm not sure if I'm unlucky or something went wrong.

I even checked up on the Crystaldiskinfo, Diskcheckup and HD Sentinel, and they all show "healthy".

I tried to run the Conveyance test on GSmartcontrol but two drive I've connected shows that they are not SMART Supported.

Do I just assume that all 3 drives were handled terribly during shipping and go to the local Costco to have then exchanged?

Yes. Don't risk your data.
Whenever someone asks a question that starts with "Why do they..." or "Why don't they...", the answer is always a) money, b) stupidity, or c) both.

It's costco. So ya exchange it. Why are you even asking when it is your right to do so?

But for your own curiousity you can try a different computer, different usb port, different usb cable. And also try the Seagate Tools test. I would still exchange it just in case.

Thanks, I wanted to avoid going to the store if possible but if need be, I'll exchange it.

For the Seagate Tools test, is the Long Generic test same as the extended test on the WD?

I don't know what it is with these mybooks but the one I also got from Costco crashed about a year later and I lost my music collection completely. I didn't shuck the drive and as I read more on it, it appears that WD uses some sort of proprietary software with these drives when used as intended USB drives. Now as a precaution, I have two backups - one on a WD and the other on a Seagate.

yes should be same. Neither one writes to it and just checks for bad sectors.

The ironic thing is that if you had shucked it you could have recovered the data easier.

That's true. But I didn't have a NAS or an external hard drive dock to use it with at the time - I actually tried to use the product as it was designed and got spanked.

My third drive passed with 1 reallocated sector count and no pending sector counts. I'm going run a final one for the first two drives. The reason why I am is that I had the computer set up so that it'd go to sleep after a certain amount of time. I don't know if that affects it but this time it's set to never sleep so fingers crossed.

If all fails, exchange time.

So I ran the test again but this time realised that my computer's power setting was so that it'd go to sleep after a certain time. Would this have affected the test? Also, I ran the test on 1 of the 2 drives and the SMART info showed raw value of 1 for each raw read error rate and the reallocated sector count. Should all the raw value on the SMART be 0? Should I just exchange the drives?

I dont know if powering it down in between a test means you should restart it. My instinct is to say yes because if you ran the HDD for hours on end the platters are of a certain temperature. Cooling it down might affect the test if a positive way, perhaps. I would restart it.

If you're getting even 1 bad sector for a new HDD in the first month I would return it. It's costco so do it. It could be a growing bad sectors situation where the more you use it the more damaged it becomes. That can happen due to physical impact when the head keeps hitting the platter at certain sectors. Return all of it. Dont waste any more time on this. You should never be getting bad sectors this early on.

No, many raw values are not zero. Temperature for example, start/stop count, power cycle count etc. Even a single reallocated sector count is a red flag for a new drive. Exchange it.
Run short tests. SMART data is cumulative. It will show previous problems. The fact your computer went to sleep during the long test can definitely affect the results. I even wonder how you could get the results at all in this case.

Well zeros in sense of the sector counts and stuff. Temperature for sure won't be zero Smiling Face With Open Mouth And Cold Sweat

I'll be exchanging the 3 drives i bought. Might as well take advantage of Costco's return policy.
