How to mount ExFAT USB drive

[joe mcguckin]

I have a 5G portable USB drive, Apple reports is as an ExFAT drive.

How do I mount it on FreeBSD? I’ve tried the following:

mount -v -t msdosfs /dev/da30p2 /t

and I get the following error:

/dev/diskid # mount	-v -t msdosfs /dev/da30p2 /t
mount_msdosfs: /dev/da30p2: Invalid argument
