Please be so kind and help me.:confused:

Thnx for your extra time

$logfile indicates unclean shutdown (0,0) Failed to mount’/dev/sdc1’:
Operation not supported Mount is denied because NTFS is marked to be in use.
Choose one action:
Choice 1: If you have Windows then disconnect the external devices by clicking on the ‘Safely Remove Hardware’ icon in the Windows taskbar then shutdown Windows cleanly.

Choice 2:If you don`t have Windows then you can use the ‘force’ option for your own responsibility.For example type on the command line:
mount -t ntfs-3g/dev/sdc1/media/SCSI1_VOL1-oforce Or add the option to the relevant row in the /etc/fstab file: /dev/sdc1/media/SCSI1_VOL1 ntfs-3g force 0 0

So best is choce #2 do you thing
