Can't resize my exFAT partition

br flag

I have an exFAT partition that I can't resize, with GParted nor Ubuntu Disks.

Here is what I see with Disks

enter image description here

And GParted shows this warning when I display the information of this device:

Unable to read the contents of this file system!

Because of this some operations may be unavailable.

I tried running Gparted with sudo -i gparted, this does not change anything.

This device is not read-only, I can delete files if I want.

I tried running sudo ntfsfix /dev/sdb3 and here is the result:

Mounting volume... NTFS signature is missing.
FAILED
Attempting to correct errors... NTFS signature is missing.
FAILED
Failed to startup volume: Invalid argument
NTFS signature is missing.
Trying the alternate boot sector
Unrecoverable error
Volume is corrupt. You should run chkdsk.

(PS: I'm open to suggestion if there is a better file system to share files between Linux/Windows/MacOS)

exFAT is probably the best alternative to share files between all 3 main operating systems, Linux/Windows/MacOS. It is best to use Microsoft tools to modify Microsoft file systems (and exFAT is a Microsoft file system). So do it in Windows.

`ntfsfix` is only for NTFS partitions. You need to install the proper exfat tools - `exfat-tools` and `exfat-fuse`. However, these are more or less for *reading* exFAT partitions, not modifying them. You should probably be booting to Windows to resize the exFAT partition, or do it by hand on the command line. Also, *never* use `ntfsfix` for non-NTFS partitions

FYI also, even with exFAT tools installed, GParted only has support for moving and copying partitions, not creating, growing, shrinking, checking, labeling, or doing UUID functions with them. You can see this in View > File System Support in GParted. Ubuntu/GNOME Disks inherits the same levels of functionality, and these're usually indicators system-wide of support, not just with these tools.

Ok, thank you for your comments, I'll try later on a Windows machine!

As pointed out in the comments, it's hard (impossible?) to resize an exFAT partition in Ubuntu.

I managed to resize my partition with the use of DiskGenius, as advised in these SuperUser answers: https://superuser.com/questions/511819/resize-exfat-hard-drive & https://superuser.com/questions/393132/shrink-exfat-partition

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
