In Linux, when you try to umount a filesystem and Linux says it's busy that means that a Linux program has a file open on the filesystem concerned. Often this is a program which was started with it's current directory on that filesystem.

Have a look at the fuser command which can tell you which processes have files open on a filesystem so you can close them down or kill them off. Once you have no Linux processes with files open on the filesystem then you should be able to umount it.

This is still causing problems. Anytime I try and gain information about this samba-mounted share, (including the fuser or umount commands) I simply get "Input/output error". I wondered if the fault lies in me changing the share to "full share" from "read only" from the windows side of things,while it was still mounted. (Changing it back doesn't make a difference). Jenny.
