RW permissions on External HDD


Hello all,

I have a problem with my external hdd, I mounted it manually and in the mount table it says ive got rw permissions. But when i try to change permissions it says:

chmod: changing permissions of `whatever': read-only filesystem.

This is my mount table:

[root@localhost ExtHDD]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/sda1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/sdb1 on /media/ExtHDD type ntfs (rw)

What am i doing wrong?

try
Code:
/dev/sdb1 -o umask=0 /media/ExtHDD
The umask=0 sets everything in the file system to world writeable, so anyone can write to it.

Hi,

Your HDD file system is NTFS, not supported for such things.
Format the drive as ext3 or ext4 file system.

wrong.
1. there's http://kernel.xc.net/html/linux-2.6.33/x86/#NTFS_RW (unfortunately disabled by default)
2. ntfs-3g is rw (unfortunately user-level)

Hi,

In Ubuntu it is there I do have NTFS partition mounted in read write mode.

What I mean is, Is it possible to use more then that? eg: ACL

The NTFS ACLs are used to control access to files or directories. On linux they are translated into ownership, permissions and Posix ACLs parameters.

File system issues

Hi,

I was wondering where to append, or run this block of code?

Code:
/dev/sdb1 -o umask=0 /media/ExtHDD

I've been beating my head against the wall trying to get my external drive to mount not as 'read-only'. This seems to have happened after upgrading to Lucid Lynx...
