Why don't you call LE? <blockquote type="cite">On 20 May 2010 12:56, "Rowan Berkeley" <<a href="mailto:rowan.berkeley@googlemail.com">rowan.berkeley@googlemail.com</a>> wrote: Hi, Having copied all the files from my external disk drive into onboard memory, and checked that they are accessible and function normally, I have created a new EXT3 file system on the external disk drive. There is now nothing on the external disk drive except an empty 'Lost and Found' folder. However, I cannot copy any of my files back to the external disk drive, because it says I do not have permissions to write to this destination. The properties tab for the external disk drive says 'permissions could not be determined.' I cannot imagine what could cause this, since everything that was on the drive has been deleted. Does anybody know how I can change the permissions? I do not know how to log in as root on this computer, since Linux Emporium never told me, though I could ask them. It would presumably be easier to change the permissions using 'sudo', if root privileges are required, wouldn't it?
