I have personally experienced seriously fragmented NTFS volumes that would no longer boot. Only solution was to wipe and reinstall.
Even Microsoft recommends you defrag your drives. Hopefully someday they will be like Netware which writes to the disk contigously [never the need for defrag]
Red can mean files not movable like database files, program files and some games.
