    Permission issues

    Well, I have an issue with Ubuntu and I feel it would be best if I tell what has been done so I can correct it.
    I had NAS setup on a old PC using NASlite. It had over 350BG of data stored on it and the format of the drive is ext2.
    Well I wanted something that could do backups to an external hard drive on that machine and Naslite doesn't support that.
    So I decided to use a old 10GB hard drive and install Ubuntu 8.04 on it using the old NAS PC, (by the way during the install I had the original NAS hard drive disconnected so I would not accidentally format it).
    Well the install went so well got the OS running, joined my work group and then I connected the original NAS hard drive with the 350GB of data on it.
    When I connected it asks for my password the mount it, then I created a shared folder on that drive and moved the original NAS data into the newly created shared folder. No problem. I can see the shared folder write to it, make modifications etc.

    Well here is my problem:
    The original NAS hard drive's contents have their original folder and file permissions so I can not modify them only read them with the shared folder.
    I tried change the permissions but the sub folders and files do not inherit the parents permissions using the GUI. So it didn't work.
    So I tried using the terminal to change it, but I do not know how to tell the terminal to change to the original NAS hard drive? It is mounted but it will switch to it.

    When I type in mount in the terminal this is what I get:

    /dev/sda1 on / type ext3 (rw,relatime,errors=remount-ro)
    proc on /proc type proc (rw,noexec,nosuid,nodev)
    /sys on /sys type sysfs (rw,noexec,nosuid,nodev)
    varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755)
    varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777)
    udev on /dev type tmpfs (rw,mode=0755)
    devshm on /dev/shm type tmpfs (rw)
    devpts on /dev/pts type devpts (rw,gid=5,mode=620)
    lrm on /lib/modules/2.6.24-19-generic/volatile type tmpfs (rw)
    securityfs on /sys/kernel/security type securityfs (rw)
    /dev/sdb1 on /media/NAS_Disk-1 type ext2 (rw,nosuid,nodev,uhelper=hal)
    gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev)

    The drive is listed as /dev/sdb1 on /media/NAS_Disk-1 type ext2, but how do I get the terminal to switch to it so I can change its permissions?

    Would someone be willing to help me? I want the original 350GB of data to inherit the parents (shared) folder permissions, so I make changes to the data as necessary. I need to change the owner, group and other permissions.

    Any help would be greatly appreciated. Thank you.

    Re: Permission issues

    Having just added a new HD myself all I had to do was open a terminal, change to the directory that it was mounted on and then change the permissions for the copied over files with chmod -r

    In your case it would be something like:
    cd /media/NAS_Disk-1
    sudo chmod -r <permissions> <files>
