gksudo problem with permissions with usb key
Hi all,
I am an ubuntu 8.04 hardy heron user. I use to edit files in multiple partitions and drives until now. Especially, I use the command gksudo nautilus. The strange thing is that I can do all I want as root in my linux partition, windows xp partition and also in usb external hd. But I can only read the second usb storage device 16 GB. I've tried to change permissions with my root powers by right-clicking a file in the usb key and setting them...but Ubuntu answers me: "The owner couldn't be changed - Sorry coldn't change the permissions of filenale:error setting permissions:read only file system" I thought that as Root I am able to edit or delete all things but it seems it's not true. In Windows XP I can use usb keys in the same way I used a floppy disk once. Where is my mistake? Have I to change my fstab? This is the current one: ========== fstab ========================= # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/sda5 UUID=5bcb6d93-d4ef-43d7-b01b-bb89e48e5711 / ext3 relatime,errors=remount-ro 0 1 # /dev/sda6 UUID=3e5efeb4-75d3-4d93-abbf-b3154ec0ebe9 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0 ============================================ Thanks in advance Enrico |
Is the problem usb drive formatted ntfs and, if so, do you have ntfs-3g installed? It's necessary for write support to ntfs partitions.

umount /path-to-usbfolder mount -t ntfs-3g /dev/usbdevice /path-to-usbfolder Though I'd find out how to modify the scrip. You could also use fat32 for the usb device, that's the easiest way to transfer files from linux->windows and vice versa. |
I'll post you the result of sudo fdisk -l in order to have a better view of my system:
----------------------------- djangou@djangou-desktop:~$ sudo fdisk -l Disk /dev/sda: 300.0 GB, 300069052416 bytes 255 heads, 63 sectors/track, 36481 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xa3b4a3b4 Device Boot Start End Blocks Id System /dev/sda1 * 1 13030 104663443+ 7 HPFS/NTFS /dev/sda2 13031 36481 188370157+ 5 Extended /dev/sda5 13031 35525 180691056 83 Linux /dev/sda6 35526 36481 7679038+ 82 Linux swap / Solaris Disk /dev/sdb: 4232 MB, 4232839168 bytes 255 heads, 63 sectors/track, 514 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x49e2a461 Device Boot Start End Blocks Id System /dev/sdb1 1 515 4133375+ b W95 FAT32 Partition 1 has different physical/logical beginnings (non-Linux?): phys=(0, 1, 1) logical=(0, 8, 9) Partition 1 has different physical/logical endings: phys=(514, 254, 63) logical=(514, 156, 25) Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x5ec40f76 Device Boot Start End Blocks Id System /dev/sdc1 1 60802 488384512 7 HPFS/NTFS Disk /dev/sdd: 16.1 GB, 16173236224 bytes 108 heads, 63 sectors/track, 4642 cylinders Units = cylinders of 6804 * 512 = 3483648 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdd1 * 1 4643 15794144+ 6 FAT16 ------------------------------ my pen drive is 16.1 size mounted on /dev/sdd1. It seems to be a FAT16 file system. So i think it is not useful to unmount a ntfs disk. For more details I append the "Properties" that appair as i plug in the pen drive.: Name: 16.2 GB Media Type: Folder Contents: 56 items totalling 22.2 GB Location: on the desktop Volume: 16.2 GB media Free space 2 GB ... Permissions The permissions of "disk-1" couldn't be determined ... Volume: Label:none size: 15.1 gb media: removable hard disk uuid: 4488-3677 file system: vfat (FAT32) Mount point: /media/disk-1 ... mount options: ro nosuid nodev relatime uid=1000 fmask=0077 dmask=0077 codepage=cp437 iocharset=iso8859-1 shortname=mixed utf8 I hope to help you. Thanks |
Code:
mount options: ro nosuid nodev relatime uid=1000 fmask=0077 dmask=0077 codepage=cp437 iocharset=iso8859-1 shortname=mixed utf8 |
Solved but not at all.
I've installed Disk manager and edited partitions in the way i think you suggested, unmounted and mounted again my external disk and now i can delete files and folders but i can' write despite I'm using the ntfs-3g drivers. These are my current settings for DATA, the usb external disk: device: sdc1 mount point: /media/DATA type: ntfs-3g And in edit sdc1: Driver:ntfs-3g (read-write driver) Mount: /media/DATA Options: defaults,locale=it_IT.UTF-8 [basic options] ... Probably i have not set properly the write ntfs option. Have you advice for unskill people? Gratefully, Enrico & Verdiani |
Code:
/dev/sdb1 /mnt/vista ntfs-3g defaults 0 0 |
