This Delphi and C++ Builder component enables reading and writing of disk sectors.
One potential use of this component is for distributing diskette protection. However, what really sets TDirectDisk apart is the new functions added in version 2.5 that make it easy to work with floppy disks in particular. TDirectDisk can now read and write sectors from diskettes with non-standard boot sectors.
If you're interested in trying out ANTS TDirectDisk, you'll be happy to know that a demonstration program is included with the software. This program is a disk editor, which should give you a good sense of what you can do with TDirectDisk.
