It could be a permissions problem if perhaps: 1) There are some original directories/files that you do not have permission to overwrite. 2) You copy/pasted them to the external drive, thereby creating a first copy with identical permissions. 3) You tried to do it again, which would involve overwriting the first copies. This might fail because you don't have permission to overwrite them.
Hello David and others, Well you were right about the problem not going away.I created a new partition table on the disk,a new partition and formatted it to ext2.The disk seems to be physically ok,however I cannot write to it without root permission.I would like to know what command to use to be able to write to it without root permission.Below is an example of commands that I have been using and their responses. peter@peter-System-Product-Name ~ $ mount /dev/sda1 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) gvfs-fuse-daemon on /home/peter/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=peter) /dev/sr0 on /media/GROOVE_ARMADA type udf (ro,nosuid,nodev,uid=1000,gid=1000,iocharset=utf8,umask=0077,dmode=0500,uhelper=udisks) /dev/sdg1 on /media/5a1069e0-28e6-485b-bb23-9bb6eb81f2ae type ext2 (rw,nosuid,nodev,uhelper=udisks) peter@peter-System-Product-Name ~ $ ls /media 5a1069e0-28e6-485b-bb23-9bb6eb81f2ae floppy floppy0 GROOVE_ARMADA peter@peter-System-Product-Name ~ $ chmod 755 /media/5a* chmod: changing permissions of `/media/5a1069e0-28e6-485b-bb23-9bb6eb81f2ae': Operation not permitted peter@peter-System-Product-Name ~ $ sudo chmod 755 /media/5a* peter@peter-System-Product-Name ~ $ cp whimp.aup /media/5a* cp: cannot create regular file `/media/5a1069e0-28e6-485b-bb23-9bb6eb81f2ae/whimp.aup': Permission denied peter@peter-System-Product-Name ~ $ ls /media/5a* lost+found peter@peter-System-Product-Name ~ $ sudo cp whimp.aup /media/5a* peter@peter-System-Product-Name ~ $ ls /media/5a* lost+found whimp.aup I am using Linux Mint 13.When I right click the hard disk icon and lookup permissions it says that they cannot be determined.The disk auto mounts when plugged in. regards Peter
