I'm trying to resolve a file path error problem with TortoiseSVN in this question on Stack Overflow. One of the answers suggested trying to change the drive letter of my external hard drive. How can I change the drive letter for a USB device?

I actually put this on SO for you :)

But here goes again: You can use Window's Disk Management Utility. Just right-click the drive and change Drive Letter IIRC.

Go to computer management (Right click Computer / My Computer), then click "Manage"

"Expand Storage" > "Disk Management", and right click on the drive you wish to change.

Click on "Change Drive Letter and Paths" then first remove the existing map followed by adding a new one.

you can use the USB Drive Letter Manager for Windows

USBDLM is a Windows service that gives you control over Window's drive letter assignment for USB drives. Running as service makes it independent of user privileges, so there is no need to give the users the privilege to change drive letters.

It automatically solves conflicts between USB drives and network or subst drives of the currently logged on user.

Furthermore you can define new default letters for USB drives and much more.

USBDLM is freeware.

p.s.: USBDLM is a REAL blessing if you have a lot of USB drives to manage!
