Hey, I've got a PC that runs Red Hat Linux Enterprise 3. I've got a
small office network going. I hooked up an external USB harddrive so
everybody can have a central space to save stuff to. But I mounted as
"root" and root is considered the owner, and the permissions are 755.
Nobody but root can write to the drive. I though maybe I could change
that by doing chmod to 777 but this is what I got:

[root@localhost mnt 23:33:48]# chmod 777 usbdrive1
chmod: changing permissions of `usbdrive1' (requested: 0777, actual:
0755): Operation not permitted


how do I open this drive to everybody?

What is the filesystem on the USB device? Most possibly some DOS (FAT)
derivative... and you're trying to chmod the root directory of that
device, and FAT filesystems don't conform to 'chmod' permissions.

Most possibly you can change the permissions for everything on the
device with a suitable mount option (once you figure out the filesystem,
and the correct mount option for that).
