    Unhappy [SOLVED] partition/encription issue on re-install

    I'm not sure if this is the right place or not (too many possibilities), so I will post it here until I know otherwise. That being said... I use a notebook for work and require a secure place for files in case of theft. I had dev/sda6 for that purpose and I mounted it only when needed and it was encrypted with password.

    Due to issues with file permissions , I had to re-install the OS. This time I do not have access to the dev/hda6 drive (owned as root) and get warnings when trying to unmount or encript it. I tried looking in the forums on the same issue, but I couldn't figure out how to correct it. If you don't mind helping, here is the info you need...

    # /etc/fstab: static file system information.
    # Use 'blkid -o value -s UUID' to print the universally unique identifier
    # for a device; this may be used with UUID= as a more robust way to name
    # devices that works even if disks are added and removed. See fstab(5).

    Ok, I figured it out. All I had to do was "#" comment out the /sda6 partition in the fstab file. I used the command "sudo gedit /etc/fstab" to achieve this. I then changed the partition ownership with "sudo nautilus" rebooted the system and mounted the partition manually. Using the Disk Utility I selected the option to reformat the /dev/sda6 partition. I selected the encryption button, entered a new pass-phrase and re-formatted the disk once again to enable the encryption. I can now mount and unmount manually and use that partition to secure my work.
