Maybe. It would be nice to know what kind of drive this is. "cifs" in Cygwin means a remote drive, claiming to be NTFS, but not having the expected FS flags of a real NTFS. Wilfed, can you please run $ /usr/lib/csih/getVolInfo.exe /cygdrive/z while the drive is online. Thanks, Corinna -- Corinna Vinschen Cygwin Maintainer
