External hard drive formatted by accident Need HELP!

[hellboy05]

I made a very big mistake
so last few days i have been making a lot of mistake such as using a used window pro key which to revert i had to delete everything of my computer and then restore it back as it came.
NOW i made one very big mistake i have
accidentally turned my brother External Hard Drive to Recovery Disk
here is what happened since i restore my computer because of the windows 10 pro key failure i decide to create 2nd partition on my brother external drive which already had data on it. So i created second partitions on external hdd abut 30 gb and then i started the process transferring the recovery data from my computer to the second partition that i created. When it started it deleted every thing on the External HDD then created a new partition of 32 gb and rest of data became unallocated data which was around 920 gb and he had a 300 gb of data on it and i had window 8.1 image backup and 15 gb of my data on it also so i lost it all and then i did not i had to keep external HDD on raw format so i changed it back to ntfs i used easyus recovery wizard trial to see if my data is still there. I see the data that my brother had on the drive and my window image backup there but i don't see my data that i put the before restoring my windows to factory settings.
I just want know how can i restore everything beside the window backup because even if i get it back it will be corrupted?
And also how can I create a recovery drive on the external hard drive without losing my data already on the external drive?

Hey there, hellboy05.

Your options are data recovery software (as you've already figured that one out) or a professional solution, such as a data recovery company. Since you've reformated the drive by creating an image and then again with the NTFS file system, chances are that a lot of data might be corrupted already. Not only because of that, but mostly because you have written data on that drive after reformatting it, which might have overwritten some of the files on the drive and corrupted others. Here's an article with a bunch of data recovery options which might prove useful: http://pcsupport.about.com/od/filerecovery/tp/free-file-recovery-programs.htm
Using the Windows tool to create a recovery drive would always reformat the destination drive before creating it. That why most people use flash drives for that.

Hope that helps.
