Hi,
I'm currently working on bug #17037. The root cause is that GetDriveType("D:") (if D is mapped to /dev/cdrom) returns DRIVE_NO_ROOT_DIR while on Windows it returns DRIVE_CDROM when there is no disc in the D drive.
GetDriveType tries to open D:\ which is converted into \??\D:\ then ~/.wine/dosdevices/d:/ The fact is that there is a dosdevices/d:: file (symlinked to /dev/cdrom) but no dosdevices/d: except if a CD or DVD is in and mounted somewhere.
The conversion \??\D:\ -> ~/.wine/dosdevices/d:/ is done in wine_nt_to_unix_file_name (ntdll/directory.c, line 2897). I'm asking here because I wonder if modifying wine_nt_to_unix_file_name is the right thing to do and sane: it's called at several locations and I don't want to cause trouble and regressions, well, if possible.
Thanks for any advice
