Disk Jockey

Disk Jockey for macOS

Disk Jockey is a simple-to-use disk image creator and analyser for your retro computers (or emulators!).

	Disk Jockey for macOS creates images in these formats	Disk Jockey for macOS shows the contents of images in these formats (Disk-O-Matic)
Macintosh	Device images (for BlueSCSI and PiSCSI / RaSCSI) Volume images (for Floppy Emu and emulators like Basilisk II and Mini vMac)	HFS+ volumes and partitions HFS volumes and partitions MFS volumes and partitions Images in Disk Copy 4.2 format Many ISO and Toast images
Apple II	Image sets for SP2SD ProDOS floppy images and hard drives DOS 3.3 floppy images	ProDOS volumes and partitions DOS 3.3 volumes Images in 2IMG format
Atari ST	TOS floppy images in raw format (.ST)	TOS floppy images in .ST format (FAT12) TOS floppy images in .MSA format
Amiga	ADF floppy images HDF disk images (WinUAE)	ADF floppy images HDF disk images (WinUAE) Partitions inside hardfiles (like those created by HDInstTools in the Workbench)
Akai Samplers	Disk images to use in samplers
And more!	Disk Jockey can also create completely blank images full of zeroes (a bit like the dd command would do in Unix, but faster)

Disk Jockey can also perform a few neat tricks like:

• Convert an existing image that works on Basilisk II into an image that works on BlueSCSI or PiSCSI / RaSCSI
• Replace your LIDO SCSI driver by a classic driver that will improve performance in modern solutions
• Extract partitions from existing device images and inject them into new devices
• Save individual files and whole directories from your disk images on your computer (and if they’re Macintosh files, rescue their resource fork too)
• Export the structure of your disk images as JSON files for further analysis
• And more!

All versions of Disk Jockey are free 🎉, but you can always buy me a coffee if you want:

It runs natively on Intel and Apple Silicon machines. It supports Dark Mode 🤘. It’s sandboxed and has been notarized by Apple so you know it won’t mess anything up. It works offline, calls no external library and tries its best to not be a resource hog. It’s made mostly of love and coffee.

Note that you will need to move it outside of your Downloads directory (/Applications/ or ~/Applications/ would be good places).

Here is some documentation. As you’ll notice, Disk Jockey has grown a lot since #Marchintosh 2022, and so has its bag of tricks.
