All files/Directories owned by root (unable to change with "chown")


Hello Friends

I have 500 Gb external Hard drive. I just bought it and attached. What i had change only is that, In beginning it was showing it as icon "485 GB Media" on desktop.I dont remeber due to some reason i had changed its mount point & it stop mounting. Then i had made a entry in fstab to mount it.

now it is mounting under /mnt

Problem i am facing now is

I have some image file down loaded from inetrnet
i tried to use them in HTML prgramming. some of them shows error "may not have permissions".

What i see is every file on my hdd is owned by root root
i tried to change it by "chown". But i could not

any help please

You probably have mounted it as root?
Did you already thought about that?
man mount

You must mount it in the fstab as user or users

Did you use the 'chown' command with root privileges?

You can only make changes to 'root' related settings under the root account.

'su' or 'su -' will give you the root account assuming you know the root password.

Your drive appears to be ntfs, which needs some special care in order to be usable in Linux. When you had it automounting, everything was configured for you, but you have to manually configure everything now that you've gone to fstab.

First of all, in order to get safe write support, you need to be using the fuse/ntfs-3g mount system. The native Linux ntfs is only read-safe.

Second, ntfs (and fat as well) doesn't natively support *nix permissions and ownerships, so no amount of chmod or chown'ing will do you any good. These settings have to be simulated with various mount options.

Using NTFS on Linux has been covered many times in many places, so I suggest you do a little search footwork here and on google.

By the way, a better option for you would be to try to get it working under the automounter again. fstab is not really the best way to configure removable media.

Also, if the drive isn't ever going to be plugged into a Windows system, you should consider reformatting it to ext3 or another native Linux filesystem. It would be much easier for you than having to deal with simulated permissions and ownership all the time.
