Safecopy is a data recovery tool which tries to extract as much data as possible from a problematic (i.e. damaged sectors) source - like floppy drives, hard disk partitions, CDs, tape devices etc, ... , where other tools like dd would fail due to I/O errors. Safecopy includes a low level IO layer to read CDROM disks in raw mode, and issue device resets and other helpful low level operations on a number of other device classes. The project also includes a device simulator which can be used to simulate bad media for testing and benchmarking safecopy as well as other data rescue tools.
