|If you did a full format then the memory locations were overwritten. If you did a quick format then the memory locations were not overwritten and recovery is possible. I do not use Diskpart so I am not sure if 'Cleaning' with it also overwrote the memory locations as well. Once a partition is written over with 1's or random 1's and 0's then it is not possible to recover anything (not counting expensive professional recovery services).|
You should always have important files on more than one drive since you never know when one becomes corrupted, encrypted, or just dies. The more important to you, the more locations it should be saved to.
In my house, I have an internal back up drive on all desktop computers and an external back up drive for all laptops plus all of them are networked together and important stuff is saved to a similar folder on multiple computers (the family photos folder is duplicated on 4 machines). Some people use external drives and DVD's for redundancy while others use a back up drive and a cloud storage (or secure off site paid for storage), and others use a NAS and DVD's or External drives that are removed from the premises. For the future, make a plan that works for you and stick to it.
You have to be a little bit crazy to keep you from going insane.
