Hey! Keep the below tips in mind as you proceed to recover drive folder:
1). Nothing is guaranteed. Any improper operation can make your drive data irrecoverable. Moreover, even if the data shows as recoverable, you may find some or all of these drive images to be corrupted and irrecoverable. So, there is no guarantee that you can completely get everything back.
2). Do NOT perform any write processes on the drive. Just leave this drive alone and avoid writing anything new on it. Any form of write to the source drive can increase the complexity of the recovery.
3). Apply some drive data recovery software to rescue your needed data as much as possible.
