    I am surprised that someone who knows how to create a RAID array seems to be unaware of the information needed for others to help you. You are not helping yourself by being so sparse with your information. So...

    I'm going to guess at the most important piece of information that you haven't given us - the actual type of filesystem. If the filesystem is a Linux one, say ext3 or ext4, it is probably owned by root at the moment - that would be one explanation for the greying out of the create folder/document choices in the context menu. If so, you simply need to own the filesystem. You can do this by running this terminal command, suitably modified:

    Code:
    sudo chown yourusername: /path/to/mountpoint
    Substitute your login name for yourusername, don't forget the trailing colon after yourusername, and substitute the full path of the mountpoint of the mounted filesystem for /path/to/mountpoint.

    Re: Cannot create files

    I'm a Linux newbie - that's why I don't know what info you need to help.

    That's great! That's the first piece of the puzzle - I think the filesystem IS owned by root (it is ext3).

    Now how do I find out where the volume is mounted?

    How did you mount it? From the file manager or have you set up a custom mount in /etc/fstab?

    Whatever the answer, post the output of these two terminal commands and we can work that out:

    Code:
    sudo fdisk -lu
    mount
    You can copy the terminal output by highlighting with the mouse, right-clicking and choosing "Copy". You will then be able to paste the output into your post with ctrl-v. Please enclose the output between [CODE] and [/CODE] tags to preserve formatting and for clarity. The simplest way of doing this is to highlight the output in the message editor and then click on the button in the message toolbar.

    The volume is mounted with File Manager.

    Code:
     sudo fdisk -lu

    Your 1TB filesystem is on partition /dev/sdb1, and...

    ... is mounted on /media/32dcf03e-1373-4ca0-b868-ccc653b2ddb3.

    The command you need is:

    Code:
     sudo chown yourusername: /media/32dcf03e-1373-4ca0-b868-ccc653b2ddb3
    Again - substitute your account login name for yourusername. I suggest you copy and paste the /media/32dcf03e-1373-4ca0-b868-ccc653b2ddb3 part to avoid typos. The reason that is so complicated is that you do not have a partition label, and in the absence of a label, the file manager automounts on a mountpoint named with the UUID of the partition. Hence the long alphanumeric string. If you were to name your sdb1 partition Data (for example), then the file manager would create the mountpoint /media/Data which can be more convenient, if only because "Data" would then show up in the left pane of the file manager rather than "1TB filesystem" or whatever is showing up. You can label the partition with Gparted or Disk Utility.

    Re: Cannot create files

    FANTASTIC! Issue solved!

    I took your suggestion and changed the volume's label to data to make it easier for me in the future.

    Thank you very much!

    One down, a couple more to go...
