Question: On my custom-built computer, there is a chip-reader that will accept about 8 kinds of chips - you know, the ones you use in cameras. These all count as "drives" on my computer, and in the Drive Manager of the MMC console, (or you can get to it by right-clicking on "Computer" and selecting "Manage") I can set the drive letters for these devices.

However, when I plug in another flash drive, I get confused as to which drive it is - with all those other ones complicating the matter.

How can I *rename* my empty chip-reader drives? I've tried opening their "properties" in Windows Explorer - which lets me specify a name, but it won't accept anything I tell it (never had this issue in XP). When I click "Apply" in the properties dialogue, it says, 

> 
> The volume label is not valid. Please enter a valid volume label.
> 
> 
> 

But nothing I type there seems to be "valid".

So, I want to call the drives by their chip names, such as "xd drive", "sd drive", "M2 drive", etc. That way I can tell which one is which.

Answer: 
Ah, I figured it out.

***I opened computer in Windows Explorer and simply clicked, "rename".***

It worked like a charm.
It works with OR without a space, however you like. Pushing good ole' `F2` works too.

I feel kind of stupid for asking the question, now, but if it worked via properties like you'd think, there would have been no question.

You can't rename it through properties, for some reason!

You may have to [enable the setting in Windows Explorer](http://www.sevenforums.com/tutorials/6969-drives-hide-show-empty-drives-computer-folder.html).
You cannot rename an "empty" drive because the name is actually stored in the partition/filesystem. Windows is being confusing with its error messages here. If you want, you can change the Windows preference to not show the drives when they are empty, or rename the individual devices when they are inserted into the reader.
