Interpreting the Spin Retry Count S.M.A.R.T. attribute value for hard drives

All we need is an easy explanation of the problem, so here it is.

I’m confused about the Spin Retry Count S.M.A.R.T. attribute value.

On one particular hard drive, I see a raw value of 0, which the popular CrystalDiskInfo v7.0.5 interprets as a current value of 166, a worst value of 100, and a threshold of 30.

According to Wikipedia:

“An increase of this attribute value is a sign of problems in the hard disk mechanical subsystem.”

According to the ActiveSmart (by Ariolic Software) documentation:

“A decrease of this attribute value is a sign of problems in the hard disk mechanical subsystem.”

Questions:

  1. OK, which is it?

  2. Why is a raw value of 0 being interpreted as a current value of 166 by CrystalDiskInfo?

  3. I’ve always had the understanding that a raw value of of 0 for this attribute indicates that the drive has never had to retry a spin start. Is that correct?

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Confusedly, high values for Current indicate good health,
while the Threshold value indicates the lower ceiling below which health
is to be considered as poor.

So usually the value of 100 means that everything is OK.
Higher values often mean that the attribute has never been updated (implies 100).

As your Current value is 166, this only means that you never had a
Spin Retry Count error, which agrees with your Raw value of 0.
You should consider replacing the disk if Current ever drops below 30.

Last remark : I prefer Speccy
to CrystalDiskInfo, as its S.M.A.R.T. display is clearer.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
