I used an old thumb drive and formatted it for NTFS and copied a few files on it. Then I found https://docs.freebsd.org/en/books/handbook/disks/#using-ntfs which worked. So then I reformatted to exFat, using Windows 10, and putting a few files on it. From an Internet search I found the solution for exfat drives is mount.exfat, which doesn't have a man page!! But mount.exfat /dev/da0s1 /mnt *worked*. Note the following extra packages: *fusefs-exfat-1.3.0 <https://svnweb.freebsd.org/ports/head/sysutils/fusefs-exfat>* *fusefs-libs-2.9.9_2 <https://svnweb.freebsd.org/ports/head/sysutils/fusefs-libs>* *fusefs-ntfs-2017.3.23 <https://svnweb.freebsd.org/ports/head/sysutils/fusefs-ntfs>; * *Note the Handbook, Chapter 18 section 8, describes using NTFS, but doesn't mention exFat.* Thanks for your responses David Christensen Steven ** > _______________________________________________ > freebsd-questions@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to > "freebsd-questions-unsubscribe@freebsd.org"
