There are better tools for investigating this type of I/O issue.

You could have a read of this article that explains how to track down disk I/O

issues: https://www.baeldung.com/linux/monitor-disk-io

    Thanks Barry, I'll have a look at that. I have added disk I/O to the
    HTOP summary display at the top of its screen which has highlighted,
    in my view, that HTOP is doing things wrong, as the summary display
    says the disk I/O is 100% but the details display on what is
    performing I/O says that nothing is doing any I/O.

If you are interested in systems performance have a look at getting

Brendan Gregg's "Systems Performance" book.

    I'll have a look at getting that too, as I had an issue this morning
    when I put on the available updates with DNF, in that when DNF was
    applying the updates it locked my system out, I couldn't even move
    the mouse pointer until DNF was finished.
    
    regards,
    Steve
