Vista - Ripping with Media Player 11 creates fragmented files

When ripping to a dedicated external drive, formated NTFS, Medai Player seems
to create entirely fragmented files. As Vista does not seem to show the
fragmented state of a hard drive, I only noticed this when moving the drive
to an XP machine. The entire drive of Media player 11 ripped music was red.
It defragmented successfuly, but I have taken to ripping onto a temporary
location on the internal hard drive and then transferring to the external
drive for beautiful blue fragmentation images.

Am I doing something wrong? Is this normal? Does anyone know of or have a
fix for this?

As always, any helps is gratefully appreciated!
