[ubuntu-users] Mount Catastrophe -- HELP!

When I was getting help from the list regarding ntfs drives a
Catastrophe occurred which I just noticed. How do I fix it???
Here is the situation:
NOTICE that the "mount" command when used all by itself with no
parameters gives a listing for example:"/dev/sde2 on /media/sda2 type
fuseblk" and the /etc/fstab file (below the mount listings) gives for
that same listing
"# /dev/sda2
UUID=58BCBB80BCBB56EA /media/sda2 ntfs defaults,umask=007,gid=46
0 1"
In this single example it seems to me that the mount is associated with
the UUID (which is permissible) and the comment "# /dev/sda2" has been
replaced by the UUID. I had just assumed they were the same entities --
that is "# /dev/sda2" was a kind of alias for the UUID but now I think
the UUID has been used to replace the "# /dev/sda2" in order to
establish the physical ordering of the hard drives. This means that when
I did certain instructions such as:
"sudo umount /dev/sde1;sudo mount -o defaults,uid=ted,gid=ted,umask=007
/dev/sde1 /media/sde1"
I was operating on the wrong drive--not the drive I wanted to change.
Since this is Ubuntu and XP in a dual boot I may have messed up XP.
THIS MAY ALSO BE THE REASON WHY other machinces cannot access the Ubuntu
shares.
I need help understanding this whole problem. When I use "mount -a"
there are NO changes so my guess is that the UUIDs are as someone
(before I started to look at this problem) put into place when the
drives were installed. I don't even know how to establish what UUID is
associated with what hard drive.
