If you value your data get DiskDrill

Lost files off an external drive, simply plugged it in & let DiskDrill do the rest. Simple UI (easy for anyone to navigate), multiple recovery options, and more importantly it helps prevent further data loss. My files are back with a couple clicks & minutes, it doesn’t get better than that! If you value your data at any level whether you’ve lost it or not get DiskDrill.
