At times you might want to ensure that, no matter how many drives you have attached to you computer, when you attach a specific one, it’ll always show up with the same driveletter. You might wish to do this for backup-purposes, or for automization purposes, or for whatever other reasons you might have.
To do this, you need to connect the drive, make sure it is found and readable by Windows. Then enter the start-menu, click “run” and enter the command «diskmgmt.msc» to open the Disk Management console, as shown above.
Locate the drive you wish to allocate a different driveletter for, and right-click it. In the menu, choose «Change Drive Letter and Paths». In the menu that subsequently pops up, re-choose the drive, and press change.
Drives are allocated driveletters from A-Z, A usually being reserved for a 3.5 or 5 ¼ inch floppy disk drive, C usually being reserved for your %SYSVOL%-drive, or SYStem VOLume, the drive which contains your Windows-folder.
If you wish to assign multiple disks, you should start from Z and work your way down the alphabet.
Assign the drive letter, and press OK. A dialog box will be shown, telling you that «Changing the drive letter of a volume might cause programs to no longer run. Are you sure you want to change this drive letter?»
IMPORTANT: If there are ANY programs at all that routinely run from or gets data from this drive, you might want to reconsider doing this in the first place, or at least make sure that you reassign these changes elsewhere as well, to ensure that your system continues to run.
If you still wish to change the drive letter, press «Yes» in the dialog box. If you do not wish to do so, press «No» (pretty logical eh?).
If you press «Yes» both the dialog box where you assign the new drive letter, and the warning one will disappear. If you press «No», you are returned to the dialog box where you assign the new drive letter.
