A system and method which provides a complete software implementation of a detection process that is capable of detecting defective Floppy Diskette Controllers ("FDCs") without visual hardware inspection or identification. The approach taken includes a multi-phase strategy incorporating programmatic FDC identification, software DMA shadowing, defect inducement, and use of a software decoding network which allows the implementation of the invention to adjust to a wide range of computer system performance levels. A method and apparatus for detecting and preventing floppy diskette controller data transfer errors in computer systems is also provided. The approach taken may involve software DMA shadowing and the use of a software decoding network.
