You are so nice to share these with us.

Hello. .gho is a nortons ghost image. You have no access to this data until you install nortons on a new machine to read it. Extra steps to do, plus you have to purchase nortons. You can use free product like EASEUS disk copy and have access to your files on any machine, instead of needing to install extra software just to see your data. I have not used it but have heard good things. All you really need is to do is save your files to your 1TB disk, but if you want a complete backup just to be safe, just clone the disk with easeus and you will have an exact copy
