COPYR.DMA is a free application for making copies of hard disks with bad sectors. The application works in DOS environment and uses DMA mode. Application creates HDD copy at the intermediate carrier, where the data logical structure can be retrieved using other applications. Hard disk processing is organized via controller ports, so the application does not require HD identification by BIOS. COPYR does not use BIOS or interrupts, it does not care for file system integrity or number of logical volumes - it works with HDD in the way designed by developers (according to ATA specifications), independently of a computer, BIOS or OS. The application uses the Direct Memory Access (DMA) mode providing data exchange among the peripherals and computer RAM without using CPU, and giving higher data transfer speed compared to PIO mode.
