Does every USB change trigger a Remeasure?

Hi

My backup file system is built on an old PC and has ten drives connected via USB. It works well.

But I am curious about the Measuring process, which takes about two hours. It seems that not only connecting a new USB drive triggers it, but even innocuous USB state changes such as turning on a USB powered fan (to help cool the Seagate IronWolf drives, which often run hot).

Is it my system, or is it supposed to work that way?

Thanks

It is fine, it is doing its own thing, you only have to worry when it does not seem to be doing anything

Thanks. I agree it isn't a problem, just saying that it's inefficient. It would be good if it was more parsimonious with its remeasures.
