Western Digital WD20EARX

Hello, I bought a Western Digital WD20EARX HDD on ebay and immediately checked the SMART Status. The spin up time was at 164 current and 163 worst. Now 4 hours and 5 power up´s and power off´s later the spin up time dropped to 159 current and 159 worst. The HDD is from 2011 and has 15.000 operating hours and has 5230 power up´s. Every time i turn it on and off the spin up time value is diminishing 1. Is this something i should worry about? or is this normal? I have to say that the divice was empty when i received it and i put 800gb data on it, coul it be connected with that?

Sry for my english im from germany.

Now its 158Current and 158 worst.  Its decreasing from day to day…

Hi there and welcome to the WD community

I recommend doing a diagnostic on the drive, you can use DLG which you can get from here:

If the drive has any type of problems doing the diagnostic then i recommend to replace, if you need further information on this matter then i recommend contacting support:

You might want to back up your 800 gigs before you do a diagnostics on the drive.
