Is not a Nautilus problem. To search the problem, i go to a complete re-install of my Ubuntu 7.10. Now, i check all. The ntfs-3g installed in my computer is version 1:1.913-2ubuntu1. My computer have only a hard disk: sda1 is a Windows XP C: drive, filesystem NTFS sda2 is a Windows D: drive, filesystem NTFS sda3 is swap linux sda4 is / linux, filesystem ext3. Then, I go to copy a test file not in Nautilus (then, is not a Nautilus problem). I use the terminal. The file is test.txt I copy from terminal and paste in this comment. carmelo@ubuntu-laptop:~$ cp -p test.txt test2.txt carmelo@ubuntu-laptop:~$ stat test* File: `test2.txt' Size: 17 Blocks: 8 IO Block: 4096 file normale Device: 804h/2052d Inode: 66960 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/ carmelo) Gid: ( 1000/ carmelo) Access: 2007-11-01 20:04:59.000000000 +0100 Modify: 2007-11-01 20:04:58.000000000 +0100 Change: 2007-11-01 20:05:58.000000000 +0100 File: `test.txt' Size: 17 Blocks: 8 IO Block: 4096 file normale Device: 804h/2052d Inode: 66956 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/ carmelo) Gid: ( 1000/ carmelo) Access: 2007-11-01 20:05:58.000000000 +0100 Modify: 2007-11-01 20:04:58.000000000 +0100 Change: 2007-11-01 20:04:58.000000000 +0100 File: `test.txt~' Size: 0 Blocks: 0 IO Block: 4096 file normale vuoto Device: 804h/2052d Inode: 66948 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/ carmelo) Gid: ( 1000/ carmelo) Access: 2007-11-01 20:04:44.000000000 +0100 Modify: 2007-11-01 20:04:37.000000000 +0100 Change: 2007-11-01 20:04:58.000000000 +0100 The modify time of test.txt (origin) and of test2.txt (destination) is the same, and is OK. In a view of Nautilus, i see the modify time, and is OK. And now, copy in NTFS drive: carmelo@ubuntu-laptop:~$ cp -p test.txt /media/sda2/test3.txt cp: preservato l'orario di `/media/sda2/test3.txt': Funzione non permessa carmelo@ubuntu-laptop:~$ cp -p /media/sda2/test3.txt /media/sda2/test4.txt cp: preservato l'orario di `/media/sda2/test4.txt': Funzione non permessa carmelo@ubuntu-laptop:~$ stat /media/sda2/test* File: `/media/sda2/test3.txt' Size: 17 Blocks: 1 IO Block: 4096 file normale Device: 802h/2050d Inode: 6299 Links: 1 Access: (0770/-rwxrwx---) Uid: ( 0/ root) Gid: ( 46/ plugdev) Access: 2007-11-01 20:08:19.000000000 +0100 Modify: 2007-11-01 20:08:19.000000000 +0100 Change: 2007-11-01 20:08:19.000000000 +0100 File: `/media/sda2/test4.txt' Size: 17 Blocks: 1 IO Block: 4096 file normale Device: 802h/2050d Inode: 6300 Links: 1 Access: (0770/-rwxrwx---) Uid: ( 0/ root) Gid: ( 46/ plugdev) Access: 2007-11-01 20:09:58.000000000 +0100 Modify: 2007-11-01 20:09:58.000000000 +0100 Change: 2007-11-01 20:09:58.000000000 +0100 I think this is the problem is at the cp command. cp: preservato l'orario di `/media/sda2/test3.txt': Funzione non permessa Transaltion from my italian language is: cp: preserved the time of `/media/sda2/test3.txt': function not permitted I see You have access different from my access You: Access: (0664/-rw-rw-r--) In my computer: filesystem ext3: Access: (0644/-rw-r--r--) filesystem ntfs: Access: (0770/-rwxrwx---) Then, if i work in superuser mode: su Parola d'ordine: root@ubuntu-laptop:/home/carmelo# cp -p /media/sda2/test3.txt /media/sda2/test5.txt root@ubuntu-laptop:/home/carmelo# stat /media/sda2/test5* File: `/media/sda2/test5.txt' Size: 17 Blocks: 1 IO Block: 4096 file normale Device: 802h/2050d Inode: 6301 Links: 1 Access: (0770/-rwxrwx---) Uid: ( 0/ root) Gid: ( 46/ plugdev) Access: 2007-11-01 20:08:19.000000000 +0100 Modify: 2007-11-01 20:08:19.000000000 +0100 Change: 2007-11-01 20:08:19.000000000 +0100 And I not have the problems of preserving the time. If, from terminal, i start Nautilus, copy and paste a file is OK. Now, my report is not of a bug, and i can confirm: is not a BUG of NTFS-3G!!! Sorry. At this point, the solution is: A correct acces for the user to not have my problems with NTFS filesystem (must be Ubuntu to set this) is: change the permission of all NTFS filesystem at the same level of ext3 filesystem. Is correct? my /etc/fstab is: # /etc/fstab: static file system information. # # proc /proc proc defaults 0 0 # /dev/sda4 UUID=5b3f43f5-a935-498d-9dbb-52299fd1c696 / ext3 defaults,errors=remount-ro 0 1 # /dev/sda1 UUID=F8788F19788ED5B2 /media/sda1 ntfs defaults,umask=007,gid=46 0 1 # /dev/sda2 UUID=567ECDF67ECDCF45 /media/sda2 ntfs defaults,umask=007,gid=46 0 1 # /dev/sda3 UUID=d1b5bed4-2e03-4ef7-963c-439bd81c0f74 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0 And now, if I change UUID=567ECDF67ECDCF45 /media/sda2 ntfs defaults,umask=007,gid=46 0 1 in: UUID=567ECDF67ECDCF45 /media/sda2 ntfs defaults,umask=000,gid=46 0 1 can be I solve the problem of preserving the modify time?
