SMB is not really designed to transfer huge amounts of data. It's
better to use rsync for that (there are Windows rsync servers), as
you'll get better compression.

Cancelling the copy should not have removed your mount. It was a
mistake to remount, especially on the same mount point (/Mted-misty).

This is a little bit confusing. SMB and CIFS are basically the same
thing, but there are multiple filesystem drivers designed to let you
mount them. On Hardy at least, smbmount is a symbolic link to
/sbin/mount.smbfs , but nonetheless resulted in a cifs mount when I tested.

You usually need to give the arguments when talking about a command.
Otherwise, it's really impossible to know what you did. I did a test mount:
smbmount //***.***.***.***/USER /home/matthew/test/smb_mount -o
(the stars are private data)
It worked (albeit quite slowly). I then successfully unmounted with:

I don't see any automatic engagement here. You told it to mount, so it
did (which obviously requires communicating using CIFS)

Again, use rsync for large transfers.
