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

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

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.
