From 8aa19c7fd13dc3790dc271dede8954539bffcd4d Mon Sep 17 00:00:00 2001 From: Christian Franke Date: Fri, 23 Feb 2024 19:01:09 +0100 Subject: [PATCH] Cygwin: Map ERROR_NO_SUCH_DEVICE and ERROR_MEDIA_CHANGED to ENODEV If a removable (USB) device is disconnected after opening its raw device, R/W attempts fail with ERROR_NO_SUCH_DEVICE(433). If the raw device of a partition is used, ERROR_MEDIA_CHANGED(1110) is returned instead. Both are mapped to ENODEV(19) because does not offer a value which better matches ERROR_MEDIA_CHANGED.
