Fluxengine's Greaseweazle documentation states that most features are available when using Greaseweazle hardware. Is there anything lacking in Greaseweazle firmware that would unblock missing features? Or would effort be better...
A single-revolution **generated** SCP image containing a non-index-aligned track ought to be able to replay cleanly if flux is precisely accounted across the wrap-round. This isn't currently the case as...
SPS IPFs 1240 (APB: All Point Bulletin) and 2100 (Weird Dreams) report: ``` $ disk-analyse --format=amigados_copylock 2100_Weird\ Dreams.ipf a.ipf *** T0.1: Copylock: Reconstructed damaged track (1 bad sectors) T0.0: AmigaDOS...
The following FluxEngine ticket (https://github.com/davidgiven/fluxengine/issues/170) includes code for an efficient k-median algorithm for automatically assigning flux values to one of k (automatically determined) clusters. It shows promise in: (a) retrieving...
Original report by Matti Immonen on Facebook is failure to load Hybris (SPS IPF 1457) on a stock A500 with TEAC FD-235F-161-U after writing the IPF to disk using GW...
Problem is that the SPS IPF library returns `CapsTrackInfo.overlap` field as `-1`, which appears to mean "unknown". Since the Anco protection includes sectors crossing the index mark, we cannot correctly...
A lot of user questions are due to lack of good documentation. Not just on specifics of the command line, but general principles of imaging, and greaseweazle's approach to it....
Example: Writing T0.0 of Theme Park Mystery for Atari ST (SPS IPF #3211). This track contains a 2ms NFA. On verification the read-back track will be converted to bitcells, and...
TRDOS: All sectors on both sides have H=0 D81: H field, along with sector data, is side-swapped. Greaseweazle is correct. FlashFloppy is currently wrong.
USB MSC devices may implement write caching and require flushing on sync/close. Should investigate this: 1. Find a USB drive that advertises a write cache 2. Implement a write test...
