Change a drive letter from Command Prompt or batch script in Windows 8?

3

I have an external hard drive that I connect often to my computer. At some point it was assigned letter G: and based on that my other software works.

Nowadays, suddenly it gets letter F:

Is there any way I can use a batch script to change the letter from F: to G:. I don't mind running the batch script manually?

If so, what is the code I should use and will it need administrative permissions?

1See diskpart and yes you need admin. In theory it should have remembered the drive letter, consider changing it manually on disk management first. – Bob – 2013-07-28T18:31:45.720

@Bob: It could be that it only remembers drive letters after they have been assigned manually at least once. – user1686 – 2013-07-28T19:57:41.393

1Thanks! I have changed it a couple of times manually, but everytime it goes back to the old one. – Eshwar – 2013-08-06T14:42:41.823

There are several methods:

  • mountvol – use it once to delete an existing letter, then again to assign a new one;

  • diskpart – interactive;

  • diskmgmt.msc aka Disk Management – a graphical tool.

Whichever you choose, assigning once should be enough, the assignment will be remembered afterwards.
