Windows 11 - Drive alert warning - what does it mean

[saltwater]

I'm setting up another Blue Iris machine on a Windows 11 HP Elitedesk. First time using Windows 11. Anyway, can someone tell me what the alert triangle, exclamation mark, means against my D: drive (18TB purple drive)? Image attached. Clicking on properties there is no reference to an issue or problem.

It had a padlock icon which suggests it was configured with bitlocker so there may be an issue with that.
If you hover the mouse over the icon does it give any further info?

The open padlock as mentioned above means it has Bitlocker enabled but the drive is most likely not encrypted hence the exclamation mark.

Hovering over the drive icon doesn't reveal anything. Do I really need bitlocker enabled? The computer will be dedicated to Blue Iris. I'll be de-bloating Windows soon, similar to my other Blue Iris machine.

I just did a quick format of the drive and that removed the padlock icon.
