Integrator , sorry for being so vague, the new Hdd was installed and supplied by a techi.
He said he was installing a 2TB like the original one, but I suspect only a 1TB has been fitted.
Hdd reads total space = "931gb" Free space 818 gb . do not know how the techi formated. he has returned 3 times to fix it but failed, he says it just needs configuring, but refuses to visit again, still only recording for 24 hours . could it be a faulty HDD ?. MANY THANKS
