Certainly, no offense taken. I've sworn a great many things that turned
out not to be true, much to my chagrin.

I was looking at the man page for mount, but I was looking under options
for fat, not for ntfs.

It's just me, and I actually went superuser to copy the files I needed
to a reiserfs partition before I posted here. But I don't like using
root for non-administrative tasks as a matter of principle and I don't
like using a workaround without understanding why it's necessary. I
don't learn anything that way. <G>
And now I am really confused:

[EMAIL PROTECTED] mnt]$ mount
