"Read-Only File System" external USB HD

hi, i cant write to my external hd in knoppix. it automounts to /mnt/sda1

here is the output of mount under root:

root@ttyp1[knoppix]# mount
/dev/root on / type ext2 (rw)
/dev/scd0 on /cdrom type iso9660 (ro)
/dev/cloop on /KNOPPIX type iso9660 (ro)
/ramdisk on /ramdisk type tmpfs (rw,size=199064k)
/proc/bus/usb on /proc/bus/usb type usbdevfs (rw,devmode=0666)
automount(pid403) on /mnt/auto type autofs (rw,fd=4,pgrp=403,minproto=2,maxproto=4)
/dev/sda1 on /mnt/sda1 type ntfs (ro,nosuid,nodev,umask=000,uid=1000,gid=1000)

i see it's mounted as read only but i can't figure out how to change this, any help would be much appreciated

As far as I can see, this device is NTFS, which is not writable with Linux tools. The only thing you can do is to install captive-ntfs to make it writable (captive is included in some KNOPPIX versions and uses the Windows driver).

Any other device needs to be unmounted and then mounted again with the option -o rw

I have the same problem, trying to copy my entire hard disk to an external usb HD, but i get the same read-only file system error.

The thing is I am using INSERT which comes with captive so I should be able to write to the drive too but it doesn't allow me. Is there something I have to do to turn on captive or something? What am I missing?

Thank you for any help
