I just want to add one thing here. The folders are created on the fly if the drive exists, there is media in the drive (removable storage), or if the network share is accessable. However you get that error if they are not. Therefore you need to create the mount points to get around that. The automatic bit may be a plus on cygwin because I do know that on linux you have to create the folder you wish to mount to. Please note that the automatic mount stuff that is used in alot of distros now to make removable media automagically available to the user doesn't count. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHb9g1s1pR2j1qW+sRAvTBAJ9PYOS8oPbKj7yZz4fMBMbfZxi1hQCfYw/k 9J29mlVOqG2xD3Lco5n9Qgw= =13/p -----END PGP SIGNATURE----- -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
