Can someone tell me if those Seagate Smart Values are good?

[PhilZockt]

Hello everyone, I'm considering getting a Seagate HDD (ST4000VN006) and found an offer that also provides smart values, but unfortunately I don't know if they're good. I would be very grateful if someone could tell me if this is the case.

HDD 1
HDD 2

Hello,

For the SMART value you'd want to check the following attributes:

5 Reallocated_Sector_Ct[/INDENT] [INDENT]197 Current_Pending_Sector[/INDENT] [INDENT]198 Offline_Uncorrectable​

If non zero (in the raw value column) then the drive might have some problems.​

You might also want to look at:

4 Start_Stop_Count[/INDENT] [INDENT]9 Power_On_Hours[/INDENT] [INDENT]12 Power_Cycle_Count[/INDENT] [INDENT]193 Load_Cycle_Count[/INDENT] [INDENT]194 Temperature_Celsius​

#4 and #12 should be roughly the same or if there is a big difference, probably you'll have #4>#9 (it means the drive was put to sleep but not powered down)​

#9 gives you the "age" of the drive, here +4k hours is not even half a year.​

#193 indicates how many times the head have been parked​

#194 indicates the temperature, if there is a min/max, you'd want to look at the max to see how hot the drive has been​

Besides the attributes, you can look if any SMART tests have been run (long or short).

HDD1 shows a long that has been aborted and a short that completed without error.​

HDD2 only shows a short, competed without error.​

So on these drives, I'd say the numbers look good.
The drive didn't do any long smart tests... that is unfortunate but not necessarily a problem.
The temperature history also looks good with temperature under 40 degrees.

Some attributes can look scary like:

1 Raw_Read_Error_Rate[/INDENT] [INDENT]7 Seek_Error_Rate​

But if I recall right, Seagate has its own way of interpreting them (maybe a member with more experience in Seagate can give more insight here?) so it doesn't mean the disk is bad.​

If those are second hand drives you want to buy, I'd also advise to burn them in (like new ones), just to be sure...

First of all, thank you so much for this long and detailed explanation. As far as I've read on the internet, it's normal for the Seek_Error_Rate and Raw_Read_Error_Rate values to be high for this hard drive model, but I'm not 100% sure. But thanks anyway, now I can definitely be more sure about the purchase.
