HDD diagnostic and data recovery tool for Linux

WHDD is a HDD diagnostic and data recovery tool for Linux. It is capable of testing a hard drive with reading and writing, providing intuitive visualization of the process. Visualization or these tests is very similar to MHDD. Amongst others, there is a function for copying the device. The copying procedure algorithms are optimized for least harm to already-defective source device. The meaning of this becomes clear in a demo. WHDD may work with your hard drives on low level, sending ATA commands to device, the benefits are: * no system freeze while accessing damaged device (device is soft-reset on timeout); * better timing precision.
