responseOur itemsOur offerCables & ConnectorsGreaseweazle allows versatile floppy drive control over USB. By extracting the raw flux transitions from a drive, any disk format can be captured and analyzed - PC, Amiga, Amstrad, PDP-11, musical instruments, industrial equipment, and more. The Greaseweazle also supports writing to floppy disks, from a range of image file formats including those commonly used for online preservation (ADF, IPF, DSK, IMG, HFE, ...).
Comes with 3D printed white case (White PLA with 100% fill density). Case was designed by Tom Dalby.
Greaseweazle V4.1 is the very latest version, updating the V4 design with new features:
- Larger form factor with stronger mounting holes
- Modern USB-C connector
- Input protections (ESD, over-current)
- USB power isolation, allows Greaseweazle to be powered by external PSU along with drive(s)
Other features:
- Reads and writes 3", 3.5", 5.25", 8" disks (with suitable drive and cable)
- Buffered outputs, for communicating with older 5.25" and 8" disk drives
- Integrated power connector for directly powering most 3.5" disk drives
- Write-enable jumper can be removed for safer preservation of precious vintage disks
- Supports flippy-modded 5.25" drives
- Supports Disk-Change detection as used by Rob Smith's integration into the WinUAE Amiga emulator
- 3 user-definable outputs (eg. 8" interface REDWC signal)
- 100% factory tested, and tested again by Keir Fraser before shipping
- More information and documentation available
This listing is for the Greaseweazle V4.1 device + case only. You will additionally require:
- A disk drive (for example a PC 3.5" or 5.25" drive)

- Floppy drive power cable, or power supply
Recommended host OS: Windows 10/11, Ubuntu Linux, macOS (recent versions). Most up-to-date versions of Linux distributions should also work (but less tested).
Package included:
- 1x Greaseweazle V4.1
- 1x Perfect fit 3D Printed 2 parts case in white colour. You do not need any glue or screws, the case easily snaps together.
