Cannot create partition: "Unable to read /dev/sdd"
I connected a new internal HDD to my headless ubuntu server and would like to partition it so I can copy my existing system disk to it (the existing disk is way low on free space and the new disk is larger.)
The disk shows in /dev/sdd (there is not sdd1 or any partitions showing). Yet the new disk does not show up using fdisk -l and attempts to mount keep referring to fstab.
Code:
tom@HouseMedia:/$ mount /dev/sdd
mount: can't find /dev/sdd in /etc/fstab or /etc/mtab
tom@HouseMedia:/$ mount /dev/sdd1
mount: can't find /dev/sdd1 in /etc/fstab or /etc/mtab
I had previously mounted and partition this drive but after using dd to restore a disk image of my existing system disk, the new disk was still empty. I'm a little lost on what exactly is wrong and would appreciate some help on getting back to square one again!

You need to partition the new disk (fdisk and mk2fs) before you can mount it. If the disk is larger than 2GB then you will need to use parted (gparted) to partition the disk.
In any event you mount partitions (sdd1) not disks (sdd).

Thanks for the clarification about what I'm mounting (partitions, not disks). I get confused :)
Using fdisk to create the partitions isn't working...
Code:
tom@HouseMedia:~$ sudo fdisk /dev/sdd
[sudo] password for tom:
Unable to read /dev/sdd
tom@HouseMedia:~$
Both disks are less than 2 TB (which is what I assume you meant, not 2 GB).

Yes I meant 2TB.

If it can't see it it can't partition it. How is the HDD attached (internal, USB or eSATA)? If it is USB then what do you get withEdit: What do you get if with this
Re: Cannot create partition: "Unable to read /dev/sdd"
it's currently attached via USB but once this is all finished, I intend to connect it internally.
Aaaaand, I have no idea which one of these entries is the disk. The Seagate entry is another external usb disk that is connected. I'm not sure what the Lite-on entry would be as the new disk I am attempting to make use of is made by Hitachi. thoughts?

I assume you are using Ubuntu 12.04 and that the udev daemon didn't enumerate the Hitachi disk when you plugged it in. I would reboot the system and see what you get with lsusb again. To see all the output of sudo lshw you dump it to a file in your home dir like this
Code:
sudo lshw > hardware.txt
...then you can look for the Hitachi disk in the file.
Edit: I found it in the hardware file

restarted the server and made the output again, just to be sure.
I see the /sdd device in the output as well but I'm not sure what to do from here. Interesting, there is also /sde /sdf /sdg as well...which seems wrong. I don't have that many disks attached.

First things first -- Don't post such a long file directly to the thread. Attach it to the post. It's easier for folks that are just reading the thread. Short amounts of data should be posted between the brackets using the # icon at the top of the editor.
