What do "current", "worse" and "threshold" reallocated sectors mean in harddrive SMART info?

1

CrystalDiskInfo reports the following warning:

Number of reallocated sectors:
Current: 96
Worse: 96
Threshold: 10
Raw value: 00000000000A

But I have no idea how to read these numbers. What do the current/worse values mean in particular, and what is the threshold?

Edit

Please see below the details of the drive:

Please [edit] and provide the full smart information and the make/model of the drive. – DavidPostill – 2016-11-21T21:44:00.220

@DavidPostill, I've now uploaded a picture with the full details of the drive and SMART data. – laurent – 2016-11-22T10:01:52.997

Your drive could fail at any moment or it could last a few more months it is impossible to tell. You should perform a backup now. Keep an eye on this value - if it keeps on increasing it means failure is imminent. – DavidPostill – 2016-11-22T10:11:46.327

Sorry which value should I keep an eye on? Is that the raw value that changes over time? – laurent – 2016-11-22T10:13:45.433

Raw and Actual. – DavidPostill – 2016-11-22T10:15:23.973

Source S.M.A.R.T. Atttribute

Explanation:

  • Attributes describes the measured value of hard drive controller operations.

  • The values of an attribute are: current, worst, threshold and raw.

  • Values are normalized to a vendor specific scale. Scales could be ranged up to 100, 200 or 253.

  • Often higher values are better than lower values.

  • The threshold marks the value at which the hard drive could fail.

  • The worst value is the baddest value seen for this drive at this attribute.

  • The raw value is a vendor coded count that give, after decoding, the normal values like current, worst and threshold.

Thank you, the part I don't understand though is what value I should look at to know the current status. Since 96/96/10 all are hardcoded values, how do I know how bad the problem is? Should I look at the raw value? Does it mean I have 10 (0A) reallocated sectors out of the threshold 10? – laurent – 2016-11-22T09:26:17.523

@this.lau_ The interpretation of the numbers depends on the disk manufacturer (and how they implemented smart on the disk). That's why I said in a comment on the question "Please edit and provide the full smart information and the make/model of the drive." – DavidPostill – 2016-11-22T09:36:32.457
