NVR overwrite HDD when full

[wdeertz]

I have a NV4116E NVR device that I installed a 6TB hard drive in. I configured the system to overwrite old files when the hard drive gets full. I currently have about 45 days of videos on the NVR and have watched as the available disk space has slowly worked its way down to 40GB. At what point will the system start overwriting old files? Surely the system needs to maintain some available disk space to work so will not go down to 0GB.

I would have thought it would start overwriting when 10% disk space was available but it keeps getting lower and I'm worried the overwrite isn't going to work before the system locks up.

I recently bought the same NVR, but not the "E" version. I had a 1TB drive on the shelf, so I installed it to see how much video it would store. I've had it about a month and it holds about a week's worth of video (6 3MP and 4MP cameras, frame rate and resolution cranked up). The overwrite function seems to work fine. I watched it count down the free space as you are doing. My Free Space/Total Space is currently 0GB/931.47GB and all seems fine.

I hope this helps.

Thanks for the reply, will monitor to ensure it continues to record and overwrites older files.

Yes I installed a 4108E at my mom's house and stuck in a 750GB drive I had laying around for the time being. It took about 5 days for it to reach 0GB free with four 3MP cameras and since then it has continued to record without any issues. It automatically overwrites the oldest data with the newest, it doesn't need to leave any space vacant as the operating system runs from flash, the drive is only used for storing video.
