This is correct; just make sure that you've edited the file chssbase.ini to
reflect the fact that the tablebases are now on the hard drive.

When a tablebase position is reached, the Hiarcs engine itself accesses it
without a change of engines (this is why you get the message "Initializing
tablebases" when you load the Hiarcs7.32 engine). I recommended using Tablebase
1.0 for positions you set up yourself because A) I've had better results with it
and B) I *think* (and this is a surmise based on the behavior I've seen -- take
this with a pinch of salt) that the Hiarcs7.32 engine needs a move or two
"warning" before accessing the tablebases -- in other words, the tablebases
didn't appear to be accessed when I set up a tablebased position and used
Hiarcs7.32 for analysis of it, but when I created a position a move sooner (in
which a tablebased position was reached after an obvious capture), the
Hiarcs7.32 engine accessed the tablebases with no problem. The Tablebase 1.0
engine *always* accessed the tablebases when I set up a position that I knew was
in one of the tablebases.

Of course, all of this could easily be due to my own stupidity or some sort of
hardware problem so, as I said, take this with a pinch of salt.
