Constant disk access by /usr/local/samba/sbin/smbd?

HI all, my once-quiet TVS-871 now has disks chuntering away 100% of the time. After much searching for answers, or for methods of investigating what's going on, I installed an app called IOtop. The only disk access it shows is these; sometimes two lines, sometimes three lines; see https://imgur.com/a/WlrTh

I know virtually nothing about Linux. Can anyone suggest why these processes would be accessing my disks 100% of the time?

The only observation I can make is that an extra copy of this process is added if I manually play a video or song from the NAS on my Windows PC. I have a drive mapped in Windows Explorer, although I only use that mapped drive at night for file copies.
This happens even if I go to AppCenter and stop every app, although the only apps I have installed are Plex and Emby; see https://imgur.com/a/MFRks

A way around that is to use one of the thumbnail sizes instead. I posted your image as a "huge thumbnail".

any strange processes running via "top"

?

No, nothing at all on "top" that's > 0% apart from the IOtop process and usr/local/samba/sbin/smbd.

But I've noticed that as soon as I disconnect the drive mapping from WIndows, the disk access stops. Maybe it's something like Windows trying to index the drive - but I don't have that mapped drive selected in the WIndows indexing tool.

Windows virus scanner?

Good question. I'm not sure how to disable Defender to check that out, but I'll get looking.
