You can review SMART attributes which keep track of device's health and

This utility is part of "smartmontools" package.
Run this one-liner to see values of relevant attributes:
$ sudo smartctl -A /dev/sda | grep -E '5 Realloc|183 Runtime|197
Current|199 UDMA'
I'm not the OP, and not very familiar with smartmon / smartctl, but I ran the
recommended command on the two disks in my oldest system, and the results are
posted below. (Aside: at some point, in the near future, I'll read the
relevant manpage to better understand that output.)
I also see the advice from Dave Christensen on additional tests to run and
will try those in the near future, ideally next week.
/dev/sda is an SSD (which hold my system and doesn't get much writing),
/dev/sdb is an HDD (which holds my "user data").
Should I be worried?
