Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Here are instructions on how to format the hard disk drive so that it can be recorded onto:
1. use the remote to access the menu.
2. scroll down to HDD and press ENTER.
3. ... I just read your last posting... did you try this procedure already?
You replaced a*****with a*****
That may be too large for the DVR's disk controller. I advise returning the 3 TB as defective and get an exchange for a*****like the one that was taken out of the DVR.
2 TB might work better.
What brand is the h.264 DVR box?
Westec is a reseller and they just re-brand stuff, I think.
Is there a manufacturer's label on the back, perhaps, or the underside of the box?
I am thinking to check the specific hard disk size limits of this exact model. H.264 and Westec isn't enough information yet, for me to do so.
If you have a different DVR system, please open a New Question for it. Thank you.
