novice pb transfert données ddmultimediat vers ubuntu

[vince G]

j ai un pb de transfert de données de mon DDMultimédiat Iomega ScreenPlay vers ubuntu je n arrive pas à monter le volume.Le pc ne possède pas Windows.Voici le detail du pb: SLogFile indicates unclean shutdown (0,0) failed to mount '/ dev/sdb1':Operation non supportée mount is denied because NTFS is marked to be in use.Choose one action:Choice 1:If you have Windows then disconnected the external device by clicking on the Safely Remove Hardwar' icon in the Windows taskbar then shutdown Windows cleanly.
choice 2:If you d' ont have Windows then you can use the 'force' option for your own responsability.For example type on the commande line: mount-t ntfs-3g/dev/sdb1/media/Iomega Screenplay-0 force Or add the option to the relevant row in the /etc/fstab file: /dev/sdb1 /media/Iomega screenPlay ntfs-3g force 0 0

j ai compris qu il falait forcer certaines données mais je ne sais pas comment m y prendre,pouvez vous m aider?
