VGA-Copy
VGA-Copy was a MS-DOS program to copy floppy disks. It was able to read defective floppy disks. Development. VGA-Copy was created by the German software developer Thomas Mönkemeier. The first public version of VGA-Copy was the version 2.0. Later versions were published under the names VGA-Copy Pro and VGA-Copy/386. Some earlier versions were published by . The main code was developed in Turbo Pascal; some low-level hardware parts were written in Turbo Assembler. VGA-Copy was released as shareware. A free test version was spread through bulletin board systems and shareware CDs ; a license key file to turn the test version into a full version could be ordered for a payment. The shareware version had two limitations: it had a ten-second waiting time on startup and it was not able to write to individual boot sectors. In 1999 the latest version, 6.25, of VGA-Copy/386 was released as freeware without restrictions. It is still available for download on the author's web page. Features. VGA-Copy was popular because it could often read floppy disks with errors. It did so by automatically doing multiple read retries on errors. Furthermore, VGA-Copy  could read floppy images and saves them with the extension as a 1:1 raw copy of the floppy disk without special headers and formats. A special feature of VGA-Copy was the ability to format floppies with capacities beyond the normal specifications. It was able to format floppy disks with a specified capacity of 1.4 megabytes with up to 1.7 megabytes of capacity (see also 2M). It also supported the Distribution Media Format used by Microsoft. To access such over-formatted floppies VGA-Copy delivered a special persistent DOS driver. VGA-Copy had the ability to compress images with  the ARJ packer. It was able to scan floppies for boot sector viruses with an internal heuristic and could also scan the full floppy with F-Prot.
