Replace Lorex DVR Hard Drive 

Yeah, if you replace the drive with one that has a higher rpm, you may need a higher amp power supply. Exactly what you need would be based on what you bought. I went through this when I replaced the drive in my TiVo. Check the specs of the drive you had, Vs what you relaxed it with. You should be able to find the proper amps on google.

@CliffsHowTo I got the Seagate Skyhawk 4TB Video Internal Hard Drive HDD. Is there a specific website that sell the exact cord I need that'll plug into the lorex box

2TB I believe

I bought it from Amazon. Link in description.

Maybe too large? I think I read that the DVR will only recognize up to 2TB, which is stupid! But that may be the issue.

@@CliffsHowTo thanks, Cliff I figured it out. It was the power adapter

Hello, yes I have the same issue the NDR not recognizing the hard disk, let me find a new power adapter Thanks

@@omarr7825 the problem seems to be a lower amperage. Hope it helps

I didn’t have that issue, so I’m not sure. Try googleing the issue.

Im having the same welcome screen issue. Did you get it resolved?

Not sure on that one.
