Accessing removable media in Bash on Windows

Good news, it is now possible to mount USB media (including formatted as FAT) and network shares with drvfs on Windows 10:

Mount removable media: (e.g. D:)

$ sudo mkdir /mnt/d
$ sudo mount -t drvfs D: /mnt/d

To safely unmount

$ sudo umount /mnt/d

You can also mount network shares without smbfs:

$ sudo mount -t drvfs '\\server\share' /mnt/share

You need at least Build 16176 so you might have to opt-in to the Windows Insider programm and then update Windows. Source: https://blogs.msdn.microsoft.com/wsl/2017/04/18/file-system-improvements-to-the-windows-subsystem-for-linux/


Is there a way to access removable media from within Bash on Windows?

Update:

Apparently it is now possible starting from Windows 10 Build 16176.

No.

At the moment there are limitations on what drives are mounted:

In order for a drive to show up under /mnt/ it must meet the following criteria:

  1. The drive must be a fixed drive
  2. The drive must be formatted to NTFS.

This has been raised as an issue: Drives other than C: are not mounted in /mnt #1079. It is still marked as "Open".

To facilitate interoperability with Windows, WSL uses the DrvFs file system. WSL automatically mounts all fixed drives with supported file systems under /mnt, such as /mnt/c, /mnt/d, etc. Currently, only NTFS and ReFS volumes are supported.
