Windows 7: Changing letter drives, can't change back to D:\

Changing letter drives, can't change back to D:\

I was messing around with my HDD partition and decided to rename my D:\ drive to X:\. Well everything went smoothly but then problems emerged.

When I turn on my laptop a bunch of applications send the error message "No Disk". It says: "There is no disk in the drive. Please insert a disk into drive \Device\Harddisk2\DR3."

I usually have to click a bunch of times before the error window stops popping up. This is also happening with various applications.

I tried changing the disk letter back to D, except I can't do that since the letter D is not given as an option for the new drive letter.

When I open up regedit and go to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices both \DosDevices\D: and \DosDevices\X: exist, even though there is no partition named D:\ on my laptop.

Is there a way to force change the drive letter back to D:\, or perhaps another solution?

The problem is the letter D is not an option to select when I try to change the disk letter back to it. I'm guessing it's because the registry still has D:\ listed as in use. I don't want to delete this registry entry out of fear of damaging the OS.

Never change a drive letter once it has data on it.

Can you post a shot of disk management ?

You would most likely have to delete the partition.

The reason D isn't available is because the CD/DVD drive has now been assigned that letter. Change that first to some other letter and you will be able to use D again.

This solved it. It wasn't the CD/DVD drive, but a USB modem that I pretty much keep constantly plugged it. I feel stupid for not noticing it had the letter D assigned.
I just unplugged it and changed the disk letter back to D. Thanks!
