How can I make an external drive keep its same drive letter?
In this excerpt from
Answercast #29, I show how to assign drive letters to portable devices.
External drive letter
Assuming that you’re talking about installing it on the same machine repeatedly and have it assigned the same drive letter? In that situation… it’s supposed to just work. Windows is supposed to remember the drive letter and give you the same letter again as long as that drive letter isn’t now in use by some other piece of equipment.
If that’s not happening, the one thing that I would suggest you try is:
Go to Drive Manager and assign a drive letter manually: a drive letter of your choice.
In some cases, that seems to have been a little bit stickier in my experience. It seems to do a better job of persisting across the action of the drive being removed from the machine and reinstalled.
Assigning drive letters
I’ve got an article that will show you how to do that (for Windows XP, at least). It’s called, “Can I reassign my drive letters?” It’s roughly the same procedure for Windows 7 as well. So it’s not hard at all.
That is where I would suggest you go first.
Across multiple computers
Now, if what you’re asking is how to assign the same drive letter across multiple machines (in other words, you take this drive from machine to machine, and want it to always have the same drive letter on each one of the machines), there’s no automatic way to make that happen that I’m aware of.
The best you can do is use that assigned drive letter functionality on each machine. Assign it the same drive letter and then, presumably, that assignment will persist on each machine. But, you need to go to each machine that you’re connecting this thing to and make that assignment manually – to get the same drive letter across all of them.
