To prevent fragmentation, try to always keep a decent amount of free space on each partition. That way, the FS driver can allocate space for new files without too much fragmentation (a fragment every 2 MB or so doesn't really hurt performance). If you had enough free space on your partition when you created the mp3-files there, I don't think fragmentation is an issue here. The files likely never grew in size which would cause fragmentation. Of course, the situation changes again when the free space on your file system was already heavily fragmented even if there was enough of it. It all depends on your usage pattern of that disk to make an educated guess if that is true. The good thing about hard disks is that you can usually hear whether they are seeking or reading sequentially. If you hear a lot of seeking on sequential operations, it is time to reformat the partition or at least erase and recreate the affected files. Hope this helps, Florian Philipp
