What do "current", "worse" and "threshold" reallocated sectors mean in harddrive SMART info?
What do the current/worse values mean in particular, and what is the threshold?
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.

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:

laurent over 7 yearsThank 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?

DavidPostill over 7 years@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."
