Troubleshoot Hard drive decreasing?!

[viel]

Hello,
My disk space is changing from 729 Gb to 605 or 670 then going back up to 729!

I scanned with Avira and Hitman Pro no threats!
Help!
Thanks

Is losing less than 20GB bad?

Is losing less than 20 gb bad and getting it back again?

How often? It shouldn't be that much over a short time.

This app will generate a log of drive writes. Might help you see exactly what is being written when the space disappears:

Activity Indicator

NVT ERP will tell you what processes are running when it happens if you really want to know. A little work to set up tho. I can find the dl link if you request...

If you have VMs and are snapshotting them you will see this issue. Not sure if you are snapshotting VMs but just sayin....

Might be Windows cleaning up its update installation files etc.
