You're trying to mount the drive as a UFS filesystem; this is the default for mount. Are there no other devices starting with da0? Because usually USB keydrives are partitioned and then the first partition is formatted as FAT32. So you probably want /dev/da0s1, or sometimes /dev/da0s4 if it exist= s. It is also not a good idea to mount on /home, because it will mask your home directory. If you want to mount a disk as a normal user instead of root, there are some things that need to be set up correctly, see below. It's better to use something like: mount_msdosfs -m 644 -M 755 -o noatime,noexec,nosuid,sync /dev/da0s1 /mnt/m= ydir I've written a small shell script to do this for me; ---------------- #!/bin/sh # Mount a thumbdrive with a MSDOS filesystem DIR=3D/mnt/$USER DEV=3D/dev/da0s1 # It is assumed that $DIR exists, and is owned by $USER. # Check if $DIR is already used. if mount|grep $DIR >/dev/null; then echo "$DIR is already mounted!" exit 1; fi # Check if $DEV is available. if ! ls $DEV >/dev/null 2>&1; then echo "$DEV does not exist!" exit 1; =20 fi # Everything OK, try to mount. mount_msdosfs -m 644 -M 755 -o noatime,noexec,nosuid,sync $DEV $DIR ---------------- N.B.: - /mnt/$USER should be an existing directory, and that you should be it's owner.=20 - the script will fail if there is already an USB disk attached.=20 (it should use da1s1 in that case) - the sysctl vfs.usermount should be set to 1 to allow normal users to mount filesystems - the permissions on the /dev/da0 device whould be set such as to allow you access.
