New external HDD does not have a Disk icon in File Explorer

.
I always have identical files on my two newest external HDDs.

I have a new HDD. That will now become my "newest" HDD, so I assigned the usual drive letter T:. (The old T: was changed to S:)

I copied all files (1.2TB) from S: to T:

Only after the copy did I notice that the T: icon (the new HDD) was a sheet of paper with one corner folded down - rather than a floppy drive.

The Properties of the Drive/Folder are shown in screenshot below.

The T: Drive/Folder does not show in Disk Management.

How do I get rid of this cuckoo ?

Thanks.

I cracked this issue. Thanks (yet again) to Dell SupportAssist.

I now have a new T: drive which can actually save files - rather than a file which can't save anything except text.
From experience, we all know that files can't be used to save files. It's one of those things.

Here's a screenshot:
