To create a exFat partition which is compatible with all operating systems, I recommend using a drive with under 2TB.
This will allow you to use an MBR partition table instead of GPT, I've had issues mounting GPT exFat drives in Windows.
This could be partially because I don't know how to Windows anything.
fdisk -l
Mine for example is /dev/sdl
, because I have many disks.
Disk /dev/sdl: 114.6 GiB, 123010547712 bytes, 240254976 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xb2fdd74a
Device Boot Start End Sectors Size Id Type
/dev/sdl1 2048 2402549 2400502 1.1G 83 Linux
/dev/sdl2 2404352 2404999 648 324K 83 Linux
/dev/sdl3 2406400 240254975 237848576 113.4G 83 Linux
Note the Device list and Disklabel type which is the partition table.
fdisk /dev/sdl
Follow through with the prompts like:
Welcome to fdisk (util-linux 2.31.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): d
Partition number (1,2, default 2): 3
Partition 3 has been deleted.
Partition number (1,2, default 2): 2
Partition 2 has been deleted.
Command (m for help): d
Selected partition 1
Partition 1 has been deleted.
Command (m for help): w
The partition table has been altered.
Syncing disks.
gdisk /dev/sdl
This will show something like this, sometimes it may throw an error, the goal is to get to the Command (? for help):
prompt.
GPT fdisk (gdisk) version 1.0.3
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: present
Found valid MBR and GPT. Which do you want to use?
1 - MBR
2 - GPT
3 - Create blank GPT
Your answer: 3
Command (? for help): x
Expert command (? for help): z
About to wipe out GPT on /dev/sdo. Proceed? (Y/N): Y
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.
Blank out MBR? (Y/N): Y
fdisk -l /dev/sdl
Should now show no Devices or Disklabel.

Be careful before using the write command.

Where -n
is your disk label, I didn't care so I used meh
.

Good to go!
@Ricuxo ... I didn't wind up making an fstab entry, I think you can do this, but definitely do
mount -a
before you reboot.Use
blkid
to get the UUID.
