recognize it , KDE pops up with the autorun actions but if i open the
folder it is empty. the logs show the error.

The simplest solution to your problem is to reformat your drive to the FAT32 file system.

The error message "GEOM: da0: partition 1 does not start on a track boundary" is common and may be ignored.

If the automount is not correct, NTFS based USB's can be mounted manually.

Your USB disk is a Western Digital Passport of approx. 500 Gb in size recognized by the system as "da0":

Try this command as root:

#mount_ntfs -o large /dev/da0s1 /mnt

You can change the target mountpoint to /media, or any other pre-existing subdirectory. If the mount is successful (a large hard disk takes a few moments to complete the mount) then you will be returned to the # prompt without any error report.
