BD-Rom - L:

Any idea why its showing up with two drive letters?

So now that I've changed the BD-RE from D: to L:, D: is now free'd up.

But when I try to change my media HDD to the D: letter I'm still getting The Parameter is incorrect error message.

Anyone know what that is & how to bypass it so I can successfully change the drive letter?

Thanks.
I would do what Brink asked you to do. He really does know what he's talking about, and might be able to help you fix your issue

Normally you would rename D: to some other unused letter, then rename M: back to D: , but we need to know what the D: drive letter is currently for first. You wouldn't want to change a system drive's letter.
My two cents

Agree with sygnus21. But even Brink has to sleep sometimes!

My 1 cent:

BD-ROM drive is probably a virtual drive - did you install VirtualCloneDrive or similar?

DiskManagement will tell you, but I wonder if there is a system file on the Media partition, like pagefile or something, so Windows doesn't let you change the letter?

Johnny,

After you changed the D: to L:, log off and log on or restart the computer to apply it. Afterwards, see if it will allow you to change M: to D: now.

Ok nice, the restart worked & I was successfully able to change it to D:

But any idea why my blu-ray is showing up under two different drive letters?

Heres a pic of disk management

That's great news so far Johnny.

I'm not sure why for the BD, but you can delete both and restart the computer to hopefully have only one assigned to afterwards.

So delete them from Disk Management?

This wont hurt anything?

Everything will be back to normal with a restart?

Sorry, no. Delete the /DosDevices\(drive letter) entries for them in registry editor.
