Old Data Still Showing After Ghost

Hello,

I am using Ghost 8 to clone a drive.  I was able to make an image of the drive but when I clone it to another drive and put it in its original machine, it still shows the old data on the drive (Including the partition table).  If I put it back into the machine I cloned it on, it shows the new data perfectly imaged

The Laptop is a new Dell XPS 15 (L521x) which uses iSRT 

The Hard Drive is a 500 GB Western Digital Black Scorpio 7200 RPM

I am completely mind blown as to why something like this would happen, any assistance would be great.  If you need more info of course I would be happy to provide.

Thanks!
