This is a different issue. Older versions of mkfs.udf did not wipe all
locations on disk where other filesystems (previous filesystems on the
media) could have their identifications. So mount finds exfat signature,
tries to mount the device as FAT which fails (as UDF has already
overwritten lots of its metadata). Right, Pali?
