Fdrawcmd.sys

Fdrawcmd.sys allows you to read/write many non-standard and copy-protected disk formats from floppy disk drivers.

The driver exposes command-level access to the µPD765a floppy disk controller, making it possible to read/write many non-standard and copy-protected disk formats from your own applications. Features of Fdrawcmd.sys: custom track formatting, mixed-sector sizes, zero-based sector numbers, non-standard ID header values, track layout scanning ordered from index hole. Other special features of this driver: writing CRC errors with specific sector contents, writing sectors with missing data fields, writing truncated sectors (e.g. 8K sectors on double-density tracks), weak or partially weak sectors, duplicate sector numbers on the same track, mixed-mode track formatting, multi-pass track formatting for tighter formats, 2-drive raw track reading of Amiga disks (Disk2FDI method).
OS supported: Windows 2000, XP, 2003, Vista, 2008, and 7.
