Have you created the mount point Toshiba in the /media directory?
You need a filesystem on the device/partition, what is it?
Correct example to mount: mount -t ext4 /dev/sda1 /media/Toshiba
That would be with an ext4 filesystem, on the device sda1 meaning first hard drive, first partition.
What is on the hard drive, new? No filesystem?
Also, stop double posting as you already asked this question in another thread.
