Yes, should be, you can see from the post that I was able to recover files after formatting the drive twice.
The actual space the operating sytem has been restored on will have overwritten some of them - but any that are on the free space area of the drive - I guess most of it - should be recoverable using those free programs.
Trouble is -
any thing you write to your hard drive now - including anything you download - will be overwriting some of the files - they are still there - you just can't see them.
Best thing would be to download the recovery programs onto an external drive or another partition, run them from there and restore anything to there.
If you don't have an external drive - I would risk shrinking the main operating system partition and creating another partition on which to do the restore operation.
It needs to be big enough to hold the recovered data - but not so big that it overwrites anything as you create it.
Any idea how much space you would need to restore the most vital DATA ?
You could run a quick test with this - it does not need to be installed - just rt click the zip and Extract all - then rt click the Data Recovery and Run as Admin - it is not my first choice app. for the job , but will let you see what can be recovered .
It is also small and will not overwrite too much downloading it.

You can then decide if you want to create another partition , get the other apps. and do the recovery.
The recovery apps find the data on the HD - if you elect to recover any , they will copy it to your chosen location - the data is stil there on the hd - they just make copies.
