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.
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
