Data Compass is a hardware and software data recovery tool produced by SalvationDATA. The product uses a "3+1 Data Recovery" to restore damaged media. The product is intended to recover data from hard drives with multiple bad sectors, platter surface problems, head instabilities, or are making clicking sounds. The vendor claims to spin up hard drives using an emulated firmware rather than the drive's own firmware. This could enable recovery from damaged hardware, but this claim has not been independently verified. A software component is available for filesystem repair.
