There’s no telling how far back Data Rescue can recover data from. Theoretically, as long as the lost data has not been overwritten with new data since its deletion, it has a chance of being recovered. However, the more you use your drive, the more likely that data is to be overwritten over time.A quick scan is unlikely to pull old data, but using a deep scan you might be surprised at the amount of old data you find still resides on the drive.
