adfchk to run in Linux online



Command-line tool to check ADFs (Amiga Disk Files) for errors and viruses.

A binary is included for Windows users; Linux users are advised to compile the application themselves.

Might also compile under plain DOS; but BE WARNED! When you scan files already renamed by the TOSEC standard, consider that file names may become insanely long in no time.

This project is currently suspended! I can't currently find the time to fix/update anything with this program and hence it must be considered 'on hold' at the moment.

Sorry for the inconvenience.


  • DMS file support (please consider this still EXPERIMENTAL, thanks)
  • BOOT block virus detection support: Byte Bandit (3 variants supported [NB: encoded ones to come]), Byte Warrior, Joshua 1 + 2, Pentagon Circle 1 + 2, Little Sven, Eleni 1 (MessAngel-B), Sepultura, and Leviathan
  • FILE virus detection support: Jeff/Butonic (versions 1.31 + 3.10), SADDAM/IRAK
  • Detection of special disk formats/signatures: Rob Northen Copylock disks (DosType = 'RNC') / Quarterback backup sets (DosType = 'Qb'+number or 'QB'+number)
  • New versions now support CRC32 calculation (displayed in the log files)
  • Format-independent DMS transfer error detection (DMS!!ERR) (will also handle NDOS disks)
  • Deep-checking (automatic) of DATA blocks; now also detects errors due to: -- Bad sequence numbers -- Bad nextData pointers -- Illegal validData values (greater than 0x1E8 or less than 0x01)
