smartctl question

[Phil]

Thank you for reading this.

I've installed Xubuntu, version 22.10, on a Lenevo X131e which often 
suffers from a frozen desktop. The mouse pointer can be moved but the 
user cannot interact with the mouse. The system can sometimes be 
restarted by pressing ctl alt f1 followed by ctl alt f7. An Internet 
search shows that these symptoms are fairly common with XFCE installations.

I thought that the HDD might be the culprit so I tried:

sudo smartctl -a /dev/sda

The result looks OK except for:

187 Reported_Uncorrect      0x0032   100   100   000    Old_age 
Always       -       38654771200

Does this indicate a faulty HDD?
