Interesting thought. I can envision how a lookup for /var/xyz could
cause everything under /var to be looked up, and I can see how
/var/cache or /var/run would be frequently read. I'll try mounting a
green USB drive's file system at a third-level directory (e.g.,
/var/backups/0) or under a less popular directory (e.g., /mnt/backups)
and see if that behaves any differently.
Thanks,
Dave

enter an 'ls' command at a bash prompt. The output doesn't appear
until after my USB hard drive spins up. Note that neither
/var/backups nor any directory under it is in my shell's PATH, nor is
there any symlink to /var/backups in my current working directory.
Thus, there should be no need to read /var/backups, yet evidently
this exactly what happens.
Just a stab in the dark: Is something poking about /var/run or
/var/cache? Perhaps that's enough to look through /var. I wonder if
you could try another terminal program, just to see if it's the
terminal, itself.
Maybe strace ls, to see what it's up to.
I know with GUI programs, I had to move mountable thing to be inside a
sub-directory of my homespace. Otherwise, anything that listed ~/
would wake up the drives to count the number of files in them. So, I
feel your pain.
