This shouldnt destroy the MBR. Have you tried other usb drives? |

i got the same on diffrent usb drives, all 32fat formatet... some times it works fine on my amiga but then after i change some disks over 000. it make often A-D then over night, next day = drive error F-F. Stick on PC always the same partition is complete gone... re-partition, format, copy again the files over.... it is not only annyoing, all my save games etc. are gone again.... it makes no fun anymore. always i hope this time it is working and then after some days again all lost. like he write: all mbr complete gone, how can the software have so many rights to destroy a full partition. sticks are |

File selector sometimes writes the mbr (block zero) on some systems. It seems a feature of particular Amigas, issue has not been tracked down. Use native selection if you can (not convenient without a better display than standard three digit unfortunately) |

All said and done there's probably no good reason to allow block 0 writes. I can't think of one. Are you interested in testing a firmware which blocks such writes, or perhaps block writes until an explicit LBA change after entering direct access mode? |

One thing that may speed you up: Are you aware that you can write sectors with a special header that includes the sector number? Rather than writing at the exact rotational position? |

I may be amenable to a FF.CFG option I guess. |

Finally, is this new Amiga device driver available for download? Open source? Is it on GitHub? |

No, didn't even thought about this yet (the old/original spec explicitly mentions the index signal). |

Would require a lot of cleanup and polishing before going public (unlikely to happen this or next month). When done, it will be on github, yes. |

Okay, here is a test firmware which disallows writes outside of the mounted FAT volume. This will disallow writes to the MBR, and even to the mounted volume's own boot/BPB sector. It should prevent total trashing of the pen drive. You need to be logged into Github to follow this link: |

I wonder if this has been already fixed/merged? I have an error "Failed to generate URL to download artifact." |

Yes this is merged and fixed in latest FlashFloppy releases. |

Not filling a bug report yet and trying to figure out first if that is not a problem on my side. In short, I very often have a destroyed filesystem after quickly changing selected disk slot (meaning it is not readable by Gotek and PC anymore).
I have Gotek SFRC922D connected to Amiga with 2 buttons and simple LCD. Previously had firmware v0.9.16a and thought that this may be an error thus upgraded to v3.29. I was using HxC file selector, now FF's
How to reproduce?
Also this happened to me when I booted Amiga and was on slot 006, then directly after booting quickly changed to 000 and... boom!
In overall I understand that changing selected disk slot when Amiga writes data may destroy disk image, but did not expect that can destroy whole filesystem. Also I have a question, how to properly change slots (i.e. to select slot 000 quickly?)
