Morning Guys

I have a DS-9632NI that I am trying to link to my Synology NAS

I have followed the old hikvision with Synology PDF and it can see the nas but i am getting the message 1727817.23GB 0.00GB Size mismatch(16GB-8TB) NASR/W

I cant seem to find an actual user friendly guide to the has anyone had any experience with this and if so can you give me a hand please
