Hi,
My Dahua NVR has started throwing bad sector errors on internal disk. I have a spare WD Red 4TB disk sitting, which has been in light NAS use, but has no SMART errors.
Can there be any issues with putting this disk in the NVR ?
Cheers
 
Most big box stores put in lessor quality HDDs than that and they work for awhile.

It won't last as long as a surveillance rated drive, but then again before I knew any better and was using big box store NVRs with cheap drives, the drive always outlasted the NVR. I think it was a red in one of mine and that got recycled into 3 NVRs over a 6 year period LOL. But that was recording motion only and not 24/7 either.

If I am buying new, whats between WD Purple and Seagate Skyhawk for a 4 or 6 TB disk?

My NVR has had a 2TB Seagate skyhawk for 2 years now. It's run fine, no random glitching during playback. This is running is a fairly warm environment.
I have also got a 6TB now.

I think anything over 4TB starts to go into the 'enterprise' grade drives, as my 6TB skyhawk has included data recovery with the purchase price.
 
I opened the NVR and it had a Seagate Skyhawk 4TB disk in there. Surprised to see it going down in less than 3 years.
Anyhow, I have ordered a WD Purple now.

WD purples are well worth it! Last over twice as long in a DVR

You might try recycling your old DVR drive in your PC.
I have found windows will mark the sectors bad and still use the drive. Would not use it for really important stuff, but
I have 2 drives that are still working in a PC 3-4 years after they had the bad sector error in a NVR.

If bad sectors are showing up externally on normal operations, it may be that the 'reallocated sectors' pool has been fully used up.
Sectors found with errors are usually re-mapped by the drive itself and don't show externally.

Check the SMART attributes for impending failure counts such as reallocated sectors, pending sectors, uncorrectable sectors etc.
