Disk Management - changing drive letter

[Hoofy]

I removed the D: drive and wanted to rename the E: drive to D: but it won't let me. Any thoughts?

Update:
Silly me.
I removed the D: drive but plugged the DVD drive in and because the new drive was M:, the DVD drive assumed the D: assignment.
Renamed the DVD to E: and was able to rename the new drive as D:.

Thanks, all!

How are you trying to do it, and are you getting an error message?

Few possibilities.
D is assinged to a removable device that isn't currently connected.
You weren't logged in as administrator
Some software that's running is on the E drive so you can't rename it.

No, just the drop down doesn't have D: listed or the other USB drives.

It's strange as it's just not listed. Maybe it needs another reboot?

Thanks.

D: was a HDD that's been shelved (it started failing and getting really hot!).
There's only one account on this PC. I can rename it to every other spare letter. It was M: and now E: but I want it to be D:.
E: contains files I've created and isn't linked to from anything as far as I'm aware.

Thanks.

Update:

Sorted. Will update OP.
