http://www.linuxforums.org – I have an external fat32 hard drive. It already has some files on it. Now, I mounted it and it shows the owner to be root. fine. but when I change the permissions, it does not seem to change it. I am not able able to access the directories, even as root !. I was able to create directories, but "luckybackup" wan not able to write to it due to permissions. I take it the lucky backup is executing as root/ but even otherwise, if I do chmod ugo+rwx, why do the permissions dont change ? (no erorr message by chmod). here is the stuff: (ext drive mounted at /seagate) ================================================== === rootubuntu--seagate# chmod ugo+rwx * rootubuntu--seagate# ls -l total 128 drwxr-xr-x 10 root root 32768 2008-08-11 21:03 HPComputerKeyFolders drwxr-xr-x 9 root root 32768 2008-08-11 21:02 Other drwxr-xr-x 2 root root 32768 2007-04-06 18:27 Recycled drwxr-xr-x 6 root root 32768 2007-03-21 05:59 System Volume Information ############^^^^^^^^^^^^^has not changd it to 777 ??? wonder why############### ######################I created a directory######################### rootubuntu--seagate# mkdir ubuntuBkup rootubuntu--seagate# ls -lt total 160 drwxr-xr-x 2 root root 32768 2009-12-19 16:43 ubuntuBkup drwxr-xr-x 10 root root 32768 2008-08-11 21:03 HPComputerKeyFolders drwxr-xr-x 9 root root 32768 2008-08-11 21:02 Other drwxr-xr-x 2 root root 32768 2007-04-06 18:27 Recycled drwxr-xr-x 6 root root 32768 2007-03-21 05:59 System Volume Information ##########################further info################ rootubuntu--seagate# id uid=0(root) gid=0(root) groups=0(root) rootubuntu--seagate# chmod ugo+rwx ubun* rootubuntu--seagate# pwd /seagate rootubuntu--seagate# ls -l total 160 drwxr-xr-x 10 root root 32768 2008-08-11 21:03 HPComputerKeyFolders drwxr-xr-x 9 root root 32768 2008-08-11 21:02 Other drwxr-xr-x 2 root root 32768 2007-04-06 18:27 Recycled drwxr-xr-x 6 root root 32768 2007-03-21 05:59 System Volume Information drwxr-xr-x 2 root root 32768 2009-12-19 16:43 ubuntuBkup ############^^^^^^^^^^^^^has not changd it to 777 ??? wonder why############### any help for this newbie appreciated. --Thanks (HowTos)
