CP Command >> Permissions

I boot up Knoppix (I have Windows XP Installed), and I am trying to copy this text file I have from my harddrive to my usb flash key. I enter terminal, and type 'cp eekotest.txt /mnt/sda1' and it says read-only file..I go to the graphical interface and i right click hda2 and go to permssion, i set everything to read and write (it said EVERYONE CAN VIE THE FILE) and i hit apply to all folders etc then comes up with an error that says 'PERMISSION SET FAILED IT COULD NOT SET PERMISSIONS FOR BLAHBLABHBLABHAL) some stuid macromedia file. Any help please? Thanks!

EDIT: There is 777 permissions for my sda1 flash key.

I agree with the above poster. Make sure it's mounted as read/write.

Try to type your command with sudo.

"sudo cp bla.txt /dev/sda1/"

This will execute the command as root.

Please post the contents of your /etc/fstab file, so we can investigate the problem.
I agree with spooon and silmaril8n that it's most likely a mounting problem.

If that is indeed the case, the "sudo" approach of jk_warrior should fail too.
In any case, it would be better to use "su" rather than "sudo", unless you know how to set up "sudo" properly in the first place.

Yeah, i checked the contents of my fstab file and it had 'ro' for the hda2 which i assume means read only so i deleted that and now I could copy and everything, i think thats right or is that an unsafe approach?

the reason /mnt/hda2 is read only is b/c it is ntfs. There is support for writing to ntfs in some live cd's. I think kanotix has it, but i would google first to be sure. If you start writing to that partition without ntfs support you may find yourself in some trouble.
