I have had some system performance issues lately, and i thought the culprit might be my 3 year old HDD. (I don't know what quality it is. It was cheap but performed admirably so far.) I have no idea what is happening but no matter with what diskcheckup tool i try to readout the SMART data with i get some... interesting data.

Is it possible that the columns are getting mixed up?
Or is the raw data actually the raw data and it takes 1.4 years for the HDD to spin up? (assuming miliseconds. if it's in seconds its 1400 years) :D

Hey there, @Nobody-Important!

I highly doubt that the SMART attributes' raw value are mixed up. However, they do show that it's a quite used HDD. My recommendation is to make sure you back up all the data from it somewhere else as well to keep your peace of mind and avoid any potential data loss. Afterwards, using the HDD's brand-specific utility make sure it passes the short & long diagnostic tests. From the looks of it, you don't have any bad sectors, so data corruption shouldn't be present.

If your system is underperforming lately and you suspect the HDD, I'd suggest you simply try to swap the SATA cable and the SATA port where the drive is connected to the motherboard. A failed connectivity could just as easily affect...

A failed connectivity could just as easily affect performance. After backing up your files and swapping the connections, I'd suggest you test the HDD again and check what the SMART attributes show then.

Hope this helps. Good luck! :)

Hey SuperSoph_WD!
What exactly makes you think that the HDD is "quite used"?
What data do you read that from? The same data that displays the spinup time as 47244640257ms or s?
Thank you for the quick and nice reply btw!
I would really like to know how you can read anything from that table though because it has me completely puzzled as to what is what.

Also the HGST WinDFT test is reporting that everything is fine.

Hey there again!

I guess it could be really confusing if this is the first time you are doing an HDD diangostic test. I'm sorry I didn't give you more details in my previous post.
The Spin-Up time attribute usually indicates the average time (in ms or s) of spindle spin-up. Usually, this parameter is considered informational, but if it starts degrading or failing, it is an indication of drive aging or worse electromechanical issues.

This is why backing up on regular basis is essential to avoid any potential data loss. Analysis of the SMART attributes' threshold, current & worst values may vary depending on the manufacturer. I believe this wiki will give you more details about that.

Cheers,
