MS's filesystems may fragment *more readily* than the average Linux filesystem 
due to the way they allocate blocks, but at some point it is just plain *not 
possible* to avoid some fragmentation.  Given that I was constantly running up 
against "no more space on device" errors, it's safe to say mine had reached 
that point.

John Dong wrote a tool called pyfrag for defragmenting Linux drives.  It's not 
a low-level defrag thing, just a script that rewrites the files to try to get 
them shuffled about into having as much contiguous as possible.  On a disk with 
only 200MB free space, though, I doubt it's much use.
