Change drive letter

On my desktop I changed the drive letter on an ext HDD from N: to P:

When I plugged it into my Wn8 Laptop the drive letter was F:

I plugged it back into my desktop and it was P:

I decided to change it from my laptop but when I tried to open the "Device Manger nothing happened.

This is what I expected:

You don't change drive letters in Device Manager — you change them in Disk Management. Here's an EE article that explains it:
Running Out of Drive Letters?

Joe is correct
if you want a FIXED drive letter - use this : http://www.uwe-sieber.de/usbdlm_e.html

But if you use it more often, I suggest putting a shortcut to it on your Start Menu, Taskbar, and/or Desktop (wherever you prefer). The shortcut should be to:

%SystemRoot%\system32\diskmgmt.msc

I tried to create this shortcut but when I was prompted for a location, searched of it, I found all these!

Is this normal? To have so many?

I just realized that "Disk Management" is not an option in Device Manager but in "Computer Management"!

I would still like to create a shortcut, but with all the dskmgmt.msu  files I'm not sure which to use or how to set it up.

But even if I accomplish the shortcut, it still doesn't answer the question.

Mike,

%SystemRoot% is the technically correct way of phrasing it, but in nearly all cases (and almost surely yours), it is C:\Windows, so the shortcut you want is to this file:

C:\Windows\system32\diskmgmt.msc

There will be one such file with that name in that folder. Don't search for it. Just go straight to that file with Windows/File Explorer (or whatever file manager you use), right-click on it, and then left-click Create Shortcut. As my article should have shown (I'll update it soon), you'll get this:

place shortcut on desktop
Click Yes and you'll have the shortcut on your desktop.

> I just realized that "Disk Management" is not an option in Device Manager but in "Computer Management"!

Correct, and you can certainly get to Disk Management via Computer Management, but the shortcut will take you right there.

> but with all the dskmgmt.msu files

First, it's diskmgmt.msc, not diskmgmt.msu. Second, there's only one of interest, as I mentioned above.

Re your comment on the screenshot, one computer doesn't see the other computer's disk assignments, so when you connect an external drive on one computer, the letter assigned to it is unrelated to the letter that gets assigned when it is connected to a different computer. Regards, Joe

The original  question was answered when I learned that Drive letter changes are local, the  letter I assign on my desktop will not be the letter my laptop sees; my laptop will sees the letter I assigned to the drive when I was on that laptop.  

I thought a drive letter assignment stayed with the drive and whatever computer I plugged it into would reflect that letter.

As for Disk management vs Device manager. confusion,  I don't know why I didn't get the disk Management option when I clicked the Device Manager option, which caused me to post this.  But I just opened "Computer Management and clicked on the "Disk Management" option again and, after a slight pause, the Drive list appeared  with their graphic representations; just as I expected it to do when I posted this question, and I was able to change the drive letter.

Joe, I didn't find that file here The file isn't there

Yes, exactly!

> I thought a drive letter assignment stayed with the drive and whatever computer I plugged it into would reflect that letter.

Nope!

> As for Disk management vs Device manager. confusion, I don't know why I didn't get the disk Management option when I clicked the Device Manager option

Because they're two different things. Device Manager does not have Disk Management in it (as you've discovered, Computer Management has Disk Management in it).

> But I just opened "Computer Management and clicked on the "Disk Management" option again and, after a slight pause, the Drive list appeared with their graphic representations;

Yes, you can get to Disk Management via Computer Management. But if you use Disk Management a lot, as I do, it's an extra step, so I prefer to have a shortcut directly to Disk Management.

> I was able to change the drive letter.

Yes, Disk Management is where you change the drive letters.

> Joe, I didn't find that file here

Your screenshot shows just the folders. You need to look at the files in the System32 folder. Here's what you'll see inside the System32 folder:

diskmgmt.msc file in system32 folder
