Warranty Replacement Drive.. looks used... any worries?

Should I be worried about anything here?

#	Attribute Name        Value  Worst Threshold  Failed        Raw Value
190	Airflow temperature cel 076   032    045    In the past   24 (1 169 24 21 0)

The drive appears to have been run way too hot.

 

First, a little primer. (I reformatted the attributes a little). The value/worst/threshold columns (attributes) are referred to as normalized values. A value of 100 or higher is excellent. Values below that are ok until they dip below the threshold. At that point the drive is said to have "failed". The worst column tracks the lowest (worst) the attribute has ever gotten.

 

Looking at the airflow temperature, you see your normalized value is 76 with an airflow temp of 24C (the raw value I assume is the actual temperature C when the smart report was taken). As the temperature rises, the normalized value would decrease. When the normalized value hits 45 (the threshold), it means that the airflow temperature is as hot as it should get. I'd guess this is 50-60C - but not sure. Well, at some point in the past this drive's normalized value hit 32. (Shows it failed in the past). That could be 70C+? Those numbers in parenthesis in the Raw Value might give some clues if we knew what they meant. 169C doesn't seem possible, but who knows.

 

If you look at the drive temperature celsius, it looks very funny. The "Value" (24) is the same as the raw value (24). And the worst says 68 - if this attribute were working as normal, the worst would have to be at least down to 24. I believe this attribute is NOT following the rules for normalized values, and instead tracking the actual temperature C. 24 is the current temperature, but I believe the drive got up to a very toasty 68C at some point in the past. I'd say that was way too hot!

 

I've seen this type of thing on drives that were popped from external USB cases with poor ventilation. My guess is that this drive was such a drive and exposed to very high temperatures - probably repeatedly. That is not good for a drive IMO, but may not necessarily be a harbinger of doom.

 

I agree with RobJ that the other attributes are looking ok - so maybe no long term damage was done.

 

I recently bought a supposedly new drive that had nearly identical attributes when it arrived on my doorstep, and I sent it back screaming and yelling at the Amazon Marketplace vendor for selling me a used drive as new, that had been run way too hot.

Sorry, I didn't see that 68 or the "in the past".  Good catch, Brian.

 

194 can be taken literally, 190 is "one hundred minus", so the 076 means it's currently 24C, the 045 means a max of 55C, and the 032 means it once reached 68C, well over 55C.

 

I would Preclear it 3 times at least, and see if it holds up.  If it does, then it survived the over-temp.  I'd still monitor it for awhile.

I was pretty darn close! Said the 45 was probably between 50 and 60C, and the 32 might 70C! Didn't know that 100 minus trick.

 

I'd say based on the low hours, that this was a USB enclosure pull, and that someone (maybe the OP?) ran a pretty extensive test (maybe a preclear) on the disk while it was in the external case. And it got quite hot. I expect that's what the vendor that sold me my drive at a discount did.

 

Drive is probably fine - but I definitely don't recommend preclearing in the external sweatbox. I might consider it if I was blowing a fan on the disk the whole time - but probably not. I prefer to take my chances that my factory fresh drive has a 2% failure rate (Seagate 8T drives are about that) - which means I have a 98% chance of having a perfectly good disk. And preclear it. One time in 50 I'd be left holding the bag.

You guys are great. This drive is a warranty replacement. I just received it from the Amazon Marketplace vendor. As a warranty replacement, I did not necessarily expect it to be new. But I wanted to check it out for health before using it. I took these stats before I started my first PRECLEAR. I will run 3 preclears and see how it holds up. Thanks guys.

For giggles I will reach out to the Amazon Marketplace vendor and ask about the drives origin.
