Question

Drive letter allocation for multiple external HDD's

by handles125 / August 20, 2013 11:40 AM PDT

I have 4 laptops running windows 7 and 4 external HDDs. I need to be able to use any HDD with any laptop but for them to always keep the same drive letter (H), and yes.. I have to use the letter H. Can this be done with an autorun.inf? or is there a more simple way that I have overlooked?

Side note, I can not use any 3rd party software to achieve this.

You should be able to do that

If you go to Start -> Control Panel -> Administrative Tools -> Disk Management, you should be able to right-click the drive and assign the letter H: to it, assuming of course that the letter H: isn't already assigned to something else. Depending on what software you're going to use with the drives, you might need to label all 4 the same if you plan to interchange them.

I have tried that

That was my first thought, but it didn't work the way I expected.. What I am finding that windows can only remember one device for H:, I assume that it is remembering the device ID rather than the name.

For example, I will allocate HDD1 drive letter H:, unplug it and plug in HDD2 and allocate it drive letter H:. After that if I plug in HDD1 again it defaults to D:, where as if I plug HDD2 in again it has remembered drive letter H:.

This is what has led me to the thought that I will need to use something that will change the drive letter to H: automatically when the drive is plugged in.

Why is it so important that all the external drive are H? Changing the letter is too much work?

It's the letter we've been allocated

Without going into too much detail, the system has a large number of restrictions and changing the letter from H will cause a number of conflictions.

Does the laptop have a CD-DVD ? If yes, what drive letter

does it default to ?

If it defaults to "D"....maybe you could designate the laptop CD-DVD as "H" and let the external USB connect as "D".

That won't work..

The issue with allowing the HDDs to default to "D" is that it will cause a confliction when the HDD's that are required to be "D" are plugged in. I really need to be able to force all the HDD's into keeping the letter I've allocated.

Ok.. thought maybe you might be able to 'make a deal'
by VAPCMD / August 23, 2013 11:09 AM PDT
In reply to: That won't work..

since you've almost always got a D as a CD-DVD and you've got a lock on H to swap with.

Have you looked at using TweakUI ?
