Confusion re: new Ubuntu server built with several (full) hard drives


I'm building an Ubuntu Server based media server. I did the install with a single empty drive installed. Once the initial install was complete, I connected 8 other hard drives (most of which were already full of music and/or video files).

The first puzzling thing was when I tried to open one of these drives (which was automounted at boot up.) I was required to authenticate. "An application is attempting to perform an action that requires privileges." Why?! At first I had no idea what to use as the password. I hadn't password protected these drives. Then it occurred to me - use my Ubuntu password as though this was a sudo situation. (Was it? It worked.)

Next, I wanted to get rid of all the NTFS partitions and migrate everything over to ext4. sdb1 had nothing of value on it, so I deleted it in gparted, then created an ext4 partition which I would then use to copy over all the files from sde1. When finished, I would delete the ntfs partition on sde1, create an ext4 partition and copy over everything from sdf1, etc.... But I couldn't do it; I could copy everything from sde1, but I couldn't paste it into sdb1. In fact, I couldn't even create a new folder in sdb1.

What's going on here? Are new partitions read-only by default? If so, why? And how do I fix them?

When you create a partition as type ext4, that just gives it a label & some metadata. You still need to put a filesystem on it (format) using
Code:
mkfs.ext4 /dev/sdb1

And you will also need to mount it in a mountpoint that your user has write access to.

Thanks for all the help, everyone! I should note that I have reinstalled Ubuntu Server. The first time I installed it, I chose to install Myth, which left me with Mythbuntu and a gui. I decided I really just wanted a basic file server, so I reinstalled and now I have no gui. Below are the outputs as requested. I'm going to hit the man pages for these commands so I can better understand what we're doing here.

Code:
cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' 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).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sdc2 during installation

The drive in question don't seem to be mounted.

Try running
sudo fdisk -l
