Hey there, Lee_65.
Could you please send a screenshot of what you see about the drive in Disk Management?
You could try accessing the drive via Ubuntu Live USB/DVD, to see if it's capable of recognizing the drive properly so that you can get to your data. Another option would be to give it a go with data recovery software: https://www.lifewire.com/free-data-recovery-software-tools-2622893.
Please let me know how everything goes.
