[SOLVED] Does Defender Full Scan check external drives as well as internal?

[TYTSoldier]

I'm wondering if full scan does this or if custom is necessary.

I would think you could simply click on it and do it to find out just as fast or faster than anyone else could...

It didn't say which drives were scanned.

When I open Windows Explorer and right-click any given drive I have an option to run "Scan with Microsoft Defender....."

Selecting that immediately launches a scan on that drive.

If I cancel the scan then I get another window with four options:

Quick Scan
Full Scan
Custom Scan
Microsoft Defender Offline Scan

At the bottom is a "Scan now" button. I selected "Custom Scan", clicked "Scan now" and a window opened within which I could select what I wanted to scan.

Per @mdd1963 - you will need to simply click and test to determine if the resulting choices and actions meet your requirements.

One would have to imagine/speculate a full scan would hit all connected drives...but, I do indeed see a quick spike in activity via task manager on even my E:drive during a quick scan, but, as there is not much on it, it is difficult to guess what it might be looking for, or how thoroughly.
