Please help. My laptop died the other day and I had to create a USB recovery disc from Microsoft. I got the laptop back to working order but lost all files, this didn't worry me much. However, when I made the USB recovery disc I also had my external hard drive plugged in. For some reason, when creating the recovery disc on a USB, it has formatted my external hard drive and copied the files on the external as well. Now all my files, videos and family photos are all gone. Is there a way to recover all the files on that external hard drive? Any help is much appreciated. Thanks!

Tips for increasing the chance of data recovery
Before you start to restore your deleted or lost files, please note the following two tips which helps to increase the chance of data recovery.
- Stop using the external hard drive immediately once you have discovered the data loss on it. Because the chance of successful data recovery strongly depends on the further user's actions. If you continue to save new files on the drive, it's possible that the original data will be overwritten by the new ones. Unfortunately, there is no way to retrieve overwritten files, even with the data recovery software or service. To avoid permanent data loss, you'd better plug out the external hard drive and put it at the safe place.
- Ask for help from professional data recovery software or external hard drive recovery services. For instance, when your external hard drive is corrupted and inaccessible, if you try repairing it by your self with common lines, the operating system will keep writing new data on the drive, making the deleted/lost data irrecoverable.
