Unable to Mount exfat Volumes

[uviteru]

Hi,

For some reason, I am unable to mount any exfat volumes, even though I have the exfat-utils and exfat-fuse packages installed...

I get this message:

root@Ancalagon:~# mount /dev/sdh /mnt/testing/
mount: wrong fs type, bad option, bad superblock on /dev/sdh,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

The dmseg command gives me this:

And finally, when I run fdisk, I get this message:

root@Ancalagon:~# fdisk -l /dev/sdh
GPT PMBR size mismatch (4294967294 != 7813969919) will be corrected by w(rite).
Disk /dev/sdh: 3.7 TiB, 4000752599040 bytes, 7813969920 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes

Disklabel type: gpt
Disk identifier: 59A554D4-0D32-479F-B2FF-C146F2DE5DC5

I'm not sure what the size mismatch means, and why it is present on any exfat volume that I try to mount. I have tried it with three different volumes, and with the same result. I can the the same volumes fine in Windows, MacOS, and the QNAP version of linux.

Does anyone have any ideas what I'm missing?

Thank you!
