Or It depends on what Samba returns as file system information. Right now Cygwin expects valid inode information only from filesystems which return the FILE_PERSISTENT_ACLS flag, except for netapps (never) and nfs (always). Additionally, the returned file ID must be > 0xffffffff, otherwise we don't trust the server to generate usefule file IDs. This usually only affects remote NT4 NTFS and Samba < 3.0. Assuming your Samba drive is //server/share, please run /usr/lib/getVolInfo //server/share and post the output as reply here. As an example, this is what my Samba shares return: $ /usr/lib/csih/getVolInfo.exe //server/share Device Type : 7 Characteristics : 10 Volume Name : <corinna> Serial Number : 2469776470 Max Filenamelength : 255 Filesystemname : <NTFS> Flags : 1002f FILE_CASE_SENSITIVE_SEARCH : TRUE FILE_CASE_PRESERVED_NAMES : TRUE FILE_UNICODE_ON_DISK : TRUE FILE_PERSISTENT_ACLS : TRUE <- !!! FILE_FILE_COMPRESSION : FALSE FILE_VOLUME_QUOTAS : TRUE FILE_SUPPORTS_SPARSE_FILES : FALSE FILE_SUPPORTS_REPARSE_POINTS: FALSE FILE_SUPPORTS_REMOTE_STORAGE: FALSE FILE_VOLUME_IS_COMPRESSED : FALSE FILE_SUPPORTS_OBJECT_IDS : TRUE FILE_SUPPORTS_ENCRYPTION : FALSE FILE_NAMED_STREAMS : FALSE FILE_READ_ONLY_VOLUME : FALSE FILE_SEQUENTIAL_WRITE_ONCE : FALSE FILE_SUPPORTS_TRANSACTIONS : FALSE If your Samba doesn't set FILE_PERSISTENT_ACLS to TRUE, you have to change your smb.conf file so that it does.
