Yes, thanks, that sounds logic. However, right after installing Avast this started to happen. No other new installs och changes to the system besides uninstalling my previous AV-software. So I'm pretty sure Avast is the culprit here.
I'm very aware of when the drive spins up as it creates a lot of noise in my otherwise silent environment. Does Avast keep access logs of scanned files/drives? Any other suggestions?
Avast doesn't periodically access your drive, as an on-access antivirus, it responds to activity, scanning certain types of files as they become active. Typically if you send something to the storage drive that file/s would be scanned.
Are you able to be more specific on what is being scanned.
How are you monitoring this activity ?
Common Log locations that I know of are in two locations - C:\ProgramData\AVAST Software\Avast\log and C:\ProgramData\AVAST Software\Avast\report.
The latter is the one most likely to have any data from Avast Shields and the FileSystemShield.txt in particular, but again these reports would be activity based. However these files don't drill down that deep or the file sizes would be very large and and the activity in maintaining them could have an impact.
Is this an external or internal HDD enclosure ?
The reason I ask is my primary system is the laptop in my system spec under my posts.
That laptop has two drives, Primary C:\ is SSD and for the most part it is OS related only. My secondary D:\ Data drive is HDD and I really don't notice this when it is in use.
I have to external SSD drives used only for weekly System drive and Data drive backups.
