I mentioned, since I’d run into this problem, a while back in my post “Oh, exFAT Doesn’t Work on Linux” which then includes a fix. Here’s a slightly more updated fix for the same and another fix for mounting just the Windows 10 partition if you have a Windows 10 System Drive (i.e. the drive with the OS on it). First, the exFAT install can simply be done with the following, no need to go get it with git via a clone.
The other trick is to get a Windows 10 System Drive mounted. To do that, open up the disks application and click the gears on the drive. Then make the following settings by clicking off for “User Session Defaults”. Then you can set “Mount at system startup” and add “remove_hiberfile” to the end of the command parameters as shown. Now the drive can be mounted, just click the mount button and you should be set.
But to the rescue comes the search engine. I found some material on the matter and, as I’ve learned frequently, don’t count out Linux when it comes to support of nearly everything on Earth. Sure enough, there’s support for exFAT (really, why wouldn’t there be?)
Check out this repo: https://github.com/relan/exfat
There’s of course the git clone and make and make install path or there’s also the apt install path.
git clone https://github.com/relan/exfat.git
Then make install.
Of course, as with things on Linux, no reboot needed just use it now to mount a drive.
mount.exfat-fuse /dev/spec /mnt/exfat
To note, if you’re using Ubuntu 18.04 the support will just be available now so re-click on the attached drive or memory device you’ve just attached and it will now appear. Pretty sweet. If you want to use apt just run this command.
