Couple of things you can check:


Then you can at least indicate which process this is causing (might be your antivirus, disk defragmentation, ... )

Good luck!

Never run a disk defragmentation on a drive that is used for writing security video (new folder). It will never get to 100% defag. On a security video (BVR) disk that has 10% free space, will be 100% fragemented, because of the way BI and Windows allocates and writes disk files.

As an experiment I took A 4 TB WD purple disk that was 90% full with BVR video files off an old BI installation. Most of the files were between 1 amd 2.5 GB. The disk was not being used for BVR writes during the test. Windows 10 disk defrag, made 72 passes trying to def the disk. It still reported 42 % fragmented at the end for the run.

All defragmenting a Video disk will do is shorted the disk life.

Cheers guys auto defrag was on, that has been baffling me for a few months, for anyone else in the future...

  1. Click on the Start Menu
  2. Start typing Defrag and you'll see an option come up called Defragment and Optimize Drives. Select that.
  3. Make sure the drive you want to turn off defrag/optimize is highlighted and then click on Change Settings.
  4. Uncheck the box that says Run on a schedule
  5. Click on OK and you're done.

Thanks @Brasseye, you got me looking at mine and found mine was on too. I wonder if a Windows update did that? I could swear I had defrag turned off already.
