Normally, after being deleted or formatted, these files are not gone from the drive immediately. They are all still saving there, but the space that they occupy is labeled as “Available Space” for the new files. Therefore, you can recover your data back from your original drive, which has ever stored all your files. But this only works before anything new puts there.
As to the other drive, it may get part or none of your files because of the moving failure. Therefore, you cannot regain all your data form it.
Here is the detailed information for you to retrieve your files:
<1>. Put the original data aside to prevent any overwriting before the recovery process.
<2>. Connect it to your computer and download a recovery tool. In my opinion, iCareData Recovery Free is a fixable recovery tool for you. It not only provides the user multiple recovery options to process different recovery problems, it also allows users to recover their files and data for free. The most important thing is that I have tried it to restore my files after accidental deletion. It is quite efficient and veritable.
<3>. Start it on your computer and select the “Advanced Files Recovery” option from four. (There are four recovery options for user to select: Advanced Files Recovery, Format Recovery, Lost Partition Recovery and Deep Scan Recovery. You could choose anyone as you like.)
<4>. Hit the media that you need this free tool to scan and click “Recover”.
<5>. Mark the wanted files in the front of them after the scanning and preview your recovered files.
