Sure you can. You have to write your own defrag tool, but you can certainly 
unmount the second partition, do raw I/O to it, and then remount it[1]. If 
you had a defrag tool that would work on an unmounted partition, you could 
do this. The one that is built into Windows assumes you want your system 
live while doing this, so it deals with it, handling the fact that you're 
moving the file transparently to the users.

No you can't. You can't unmount a file system with open files on it under 
Linux either.  You can defrag it (or fsck it) while it's mounted, but 
that'll just corrupt it, most likely.



[1] For example, try "chkdsk d: /x" from an administrator command line.
