Ok I've changed my one media HDD from letter D: to letter M: & now want to change it back to letter D: since all of my files/directories are set to the D: letter.

But now Diskmanagement is giving me just about every other letter other than D: to change it to.

And when I try to change it to another letter, it gives me an error saying:

The Parameter is incorrect

Does anyone know what this error is & how I can force it to rename my media HDD letter to D: so all my directories fall back into place?

Thanks.

Ok, I did that & it seems there is still an old D: record from before perhaps?

What should I do? Can I delete the old D: record?

I've attached a screen shot.

could be maybe the (d drive) is now the system recovery drive. not real sure how that works but i think when you change a drive letter between 2 other drives the next drive takes it's place. e drive would become d drive .....
if you goto start and right click on computer then click manager then drive management you should be able to see
what the d drive is all about.

hope that helps you

Ahh its assigned to my blu-ray drive. I can rename that one too right?

I didnt see it in Disk Managment.

Try it in the 2nd option you mentioned?

Are all of those drives & letters listed in that screen shot active drives? So I wouldnt want to delete any of them right?

Can I rename my blu-ray from D: to B: or is B: not a good letter to name a drive?

if you delete the drive i think you will have to reformate it in order to use it again there for losing all your data on that drive. i'd put the blu-ray drive as the last letter. so if you have 4 drives in your system 1 being your blu-ray drive then c - d - e - f the blu-ray drive would be (f). i think this is the best way to do it so you don't mess any other drive letters up.

Johnny,

Before doing anything, could you post a screenshot of the Computer and Disk Management windows showing what each drive letter is for?

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.

Also
from a command prompt
>diskpart
>list volume
>exit

will show you what letters are assigned to what volumes.
If your Blu ray is a plug & play usb device and not permanently assigned to D: simply unplugging it should free up D:.

Ok, here is what I've found:

Apparently my cd-rom is taking up 2 drive letters

BD-RE - K: (It used to be D: but I was just able to change it)

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 ;)

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?

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?
