Trouble at t'Mill.

"Ooer Bwoy" suggested adding an extra HDD to Gaffer's computer and moving some stuff across to see if things speed up a wee bit.
It tells us that:-
A) It requires 15% free space to de-frag.
B) It then informs us it has 11% free space --- :¬((

Physical fitting ... Nae tribble, relatively speaking

Getting computer to, then, acknowledge its existence --- a whole different ball game. In fact the word "Ball(s)" was uttered many a time and oft.

On the one hand: I could find a couple of methods whereby I could actually see it existed,
on the other hand: there were at least as many to prove that the computer couldn't see/accept/acknowledge/use it.
Finally sorted courtesy of some owners/enthusiasts forum.

It may have become apparent why I refer to them, as a group, as "Disputers"
