I am curious which way OS notifies a drive that it is mounted. I believed
that drivers read and write blocks, maybe switch power save states, but
mount is performed on a higher level.
We would the drive need to be notified ?
Wrong question IMO. If as you say, and that makes perfect sense, if the
drive is boot mounted, there s/b a mechanism to advise the user that the
boot mount will be delayed until such time as the drive reports its
validation is completed. That would serve the purpose of advising the
user that its use-by date is rapidly approaching. As is, we are at the
mercy of the drive maker until it goes RO. And that most certainly is
not a desirable situation.
I think the case with u-sd's used for nearly everything in the arm
arena, seem to be capable of doing this "housekeeping" while mounted is
a good thing as I only power them down to do my mods, and my failure
rate on those is actually much better. A kill-a-watt says my rebuilt but
standing idle between jobs printers is drawing 14 watts. The pi clones
have had zero u-sd card failures in over a decade..
