FAT drives not mounting
Posted: Sat Nov 11, 2017 2:24 am
Hi there,
on my Macs with ZFS installed, some FAT drives won't automount, I have to activate them manually in diskutil. Uninstalling ZFS solves this on this machines.
So I did some research. The difference I found when doing a "diskutil info /dev/disk$$" is mainly "Content (IOContent):". The drives that don't automount have none as value. Seems that this drives don't have a partition table at all.
Can ZFS be the problem here? Is it a known issue?
