I bought a WD30EZRX two weeks ago and I check the smart data every few days. What I noticed is that the SPIN-UP TIME is decreasing and changing every time i turn on my computer.
Here a pic:
As low as 143
Is it normal to see that smart attribute decreasing so fast on a brand new drive? Also got a brand new caviar black and the smart attribute 176/176 is stable and doesn’t change evry time i turn on my pc.
EDIT: just shut off and turned on my pc again and the result is even lower now. It isn’t 156 anymore, but 149 now… as you see, it changes every time i turn on my pc, it’s weird…
I installed it and i’ll get back to you in a few days.
Still i tested two other DD (caviar black tho, not green) and the spin up time does not vary in there when i turn on my pc (I used HD-Tune and Crystal Disk info till now to check the smart infos).
As for this green i have, it varies. 156, i turn it off then on, 149, i do it again, i get 153, and as you can see, it did 143 before.
I already had to return a caviar black that went wrong after less than 6 months, so now i’m quite stressed over having to deal with bad DD for months before sending it to RMA in the end.
Thanks anyway, gonna give you more details in a few days thanks to HD Sentinel ^^
As for the spin-up time, the raw value of the attribute is 0x23F0 (= 9200 decimal). I believe that’s telling you that the drive is taking 9.200 seconds to come ready. Spin-up time is the kind of attribute that you would expect to vary. It would depend on factors such as supply voltage (+12V) and ambient temperature. The latter would affect the viscosity of the fluid in the spindle bearing.
So here i am with this spin-up time problem that’s worrying me. It seems the smart value keep decreasing. So the time it gets to load when i turn on my pc keep increasing. Now it needs almost 10 seconds… and i think i’m going to pass it this coming week)
The HDD now always stay under 150 in smart value. A week before it showed 153/156 at least, now i am always between 148 and 143 always going downward and will be under 140 soon at this rate.
