When I look at the smartclt output I can see the value also as RAW value, but the SMART count did not degrade

My questions are: <br>
<br>
<p>How serious is this error? The number of Offline_Uncorrectable
seems to be stable right now.</p>
<p>Why isn't the SMART value decreasing and still at 100? (I assume
it is because the damage is still very small).</p>
<p>If it is not critical to swap this disc right now, how can I
prevent that I get the notification from smartd every day?
Basically I only want to be notified when the values are changing,
again.<br>
</p>
<p>Thank you in advance for any insight you might be able to give.
Please let me know if you have any questions.</p>
<p>Best regards</p>
