    Hello !!! I have a question that has been bothering me for a long time. Tell me - what to look at (RAW value etc.) when evaluating the condition of a drive with SMART?
    For example, we have a disk like this: Crystal Disk Info: Understanding SMART Drive Condition with RAW, Threshold & C5 Evaluation

    It is also unstable. It's about point C5. But which value says it is unstable? Just don't give me a link to this: Link Because I've read it before but I don't understand it; (

    Or this drive: Crystal Disk Info: Understanding SMART Drive Condition with RAW, Threshold & C5 Evaluation

    How do you know if a disk is permanently damaged? By which parameters? And which values (RAW, Threshold or what?)?
    I am asking for help because I would like to understand it very much. Regards

    You have everything in the topic to which you linked.

    What do you not understand?

    The first disk has unstable sectors C5 - RAW value.
    In the second disk there are reallocated sectors 05 - RAW value.

    Just that after which the value is read the state of the disk.
    For example, I know that you are looking at points 05, 0A, B8, 0BC, C4, C5, C6.

    So if at the point C5 in the RAW value it will be 1 or more at the end, it means that the disk is unstable. Do I understand correctly?

    Added after 5 [minutes]:

    Aaaaaha, I think I understand. For example, at step 05, the RAW value cannot be greater than the threshold (ie, 5).
    So as in C5 the threshold is 0, the RAW value cannot be greater than 0. Is it right?

    Overall yes.

    If the value of 05 is greater than 0, the disk is damaged.
    If the value of C5 is greater than 0, the disk has unstable sectors.

    Some parameters may be very high for different disk manufacturers and this is not a malfunction.

    Ok, that's rather all I wanted to know is that I know. Just tell me if you are looking at the values Current and worst ?

    RAW Value - RAW (Hex)
    Attribute values - It is based on the result of this attribute parameter that we learn about the current state of the disk. It shows the raw result, e.g. for attribute 5 it is the number of reallocated sectors.
    Threshold
    This is the lowest limit for the value of various attributes. SMART compares the attribute values with the thresholds for identifying failures. The threshold number is specified by the device manufacturer. The threshold is factory set by the device manufacturer and does not change.
    Worst - Worst
    This is the worst recorded attribute value that has occurred so far. (Lowest Value recorded)
    Current - Value
    The value can be 1-100, but there are attributes that take different values. The device compares the attribute values with the thresholds. When the attribute values are greater than the thresholds, the device operates normally. (When Value is below Threshold, it indicates a failure, although it is not a necessary condition)

    Okay, it's clear :) I hope I understood correctly :) Best regards and thank you very much for your help.

Topic summary

The discussion focuses on evaluating the condition of hard drives using SMART (Self-Monitoring, Analysis, and Reporting Technology) parameters, specifically the RAW values, thresholds, and attributes such as C5 (unstable sectors) and 05 (reallocated sectors). Users seek clarity on which values indicate drive instability or damage. It is established that a RAW value greater than the threshold for attribute 05 indicates damage, while a RAW value greater than 0 for C5 indicates instability. The importance of understanding the Current, Worst, and Threshold values is emphasized, as these help assess the drive's health and potential failure risks.
