I'm one of the CircuitPython core devs. This issue is OS-dependent: Windows and Linux don't necessarily write data and metadata out to USB drives promptly. The problem is particularly acute for FAT12 filesystems on Windows, which are typically 16MB or smaller: Windows can take up to 90 seconds to flush, due to a driver bug or perhaps some ancient concerns about floppy drives. MacOS doesn't have this issue. See https://superuser.com/questions/1197897/windows-delays-writing-fat-table-on-small-usb-drive-despite-quick-removal/1203781 for details. We have contacted Microsoft about this but getting it fixed is a long-term and uncertain process. I'll test on Windows when I return from PyCon. Thank you for the prompt fix! ---------- nosy: +dhalbert _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36807> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
