Hi ..
I have brand new WD4004FZWX with just 1 day 15 hours power on time
recently I realized that I got these parameters which is I do not quite understand...
Seek Time Performance >> Threshold: 20 /Value: 128 /Worst: 128 /Status: OK
and
Throughput performance> Threshold: 54 /Value: 136 /Worst: 136 /Status: OK
Seek time performance and Throughput performance were recorded on the same day (attachment)
so
it was problem with servo then.....(seek time parameter)
I read about threshold and value >> " OK: the value is same or greater than the threshold. There is no problem. "
do I need to worry?
or
just live with it and wait till it become automatically-stable like my other drive (WD1003FZEX) (attchment)??!
thank you

Re: Throughput performance Seek Time Performance Threshold
Generally checking the Thresholds / Values / Worst fields may not really give accurate information.
They only show if the drive is above the threshold (so generally working correctly OK) or below the threshold (so failure expected).
But the Value fields
- may change frequently and even there may be big changes on the beginning of the lifetime
- may not reflect problems/degradations later in normal use, so may not be used to determine how "good" is the drive
The images you sent shows the change of the numbers in the Data field. These are marked by bold in Hard Disk Sentinel as these (for error counter attributes) are important: these are the source of how the Value fields calculated and inspecting those may give information about real errors - but only for the proper attributes.
From the values, I do not really see any problems at all.
While I do not know the total, complete status of the hard disk drive, I can confirm that these do not indicate any problems at all: the change of these numbers are completely normal.
Inspecting 1-1 single attributes and comparing with other, different model (even from same manufacturer) may be not a good idea, as these do not really show if a hard disk drive is better or not in general.
If you prefer, you may use the tests available in Hard Disk Sentinel (see http://www.hdsentinel.com/faq.php#tests for more information)
just to confirm the status, to verify that the hard disk is really perfect - or to reveal any possible problems.
Of course I can confirm that if there would be a real error, Hard Disk Sentinel would surely
- report in the text description
- show the degradation health value
- it would be detected by Disk -> Short self test or Disk -> Extended self test
- the Disk -> Surface test -> Read test could not be completed without problems
If you are interested in the relation between the Thresholds / Values / Worst / Data fields and how to interpret, please check:

Also if you use Report menu -> Send test report to developer option any time, I can check the actual complete status of the hard disk drive(s) and advise about the best ways to diagnose, reveal - and fix possible issues (if there is any).
