A native AmigaOS 3.x hard disk partition editor with full RDB (Rigid Disk Block) support.
DiskPart is a partition management tool for the Amiga, built as a clean GadTools application that runs directly on Kickstart 3.x with no external library dependencies beyond the ROM. It was created out of a simple conviction: the Amiga deserves a good, modern partition editor — and it is better to have one now than never.
"Vibecoded software might be argued with, but this is an experiment in what AI-assisted development can produce when given a clear goal and a demanding user."
Director: John Hertell — john(at)hertell.nu
Code: Claude Code (Anthropic)
- AmigaOS 3.x (Kickstart 3.1 or later recommended)
- Intuition, GadTools, DOS libraries (all standard ROM)
- ASL library optional (enables the Browse file requester in the filesystem driver dialog)
Run DiskPart from the Shell or double-click from Workbench.
- A device selector appears listing all detected disk controllers. Use Filter / Show All to toggle between storage-only and full device lists.
- Select a device and click Select — a progress window shows each unit being probed.
- Select a unit and click Select to open the partition editor.
- Use the buttons along the bottom to manage partitions and filesystem drivers.
- Click Write when satisfied to commit changes to disk.
Requires the Bartman/Abyss m68k-amigaos ELF toolchain.

This project was developed through AI-assisted ("vibecoded") collaboration — the architecture, decisions, and direction came from a human; the implementation was written by an AI. Whether that makes the software more or less trustworthy is a fair question. The answer offered here is: judge it by what it does, read the source if you want, and always keep a backup before touching partition tables.
