To prevent fragmentation, try to always keep a decent amount of free |
14 |
space on each partition. That way, the FS driver can allocate space for |
15 |
new files without too much fragmentation (a fragment every 2 MB or so |
16 |
doesn't really hurt performance). |

If you had enough free space on your partition when you created the |
19 |
mp3-files there, I don't think fragmentation is an issue here. The files |
20 |
likely never grew in size which would cause fragmentation. |

Of course, the situation changes again when the free space on your file |
23 |
system was already heavily fragmented even if there was enough of it. It |
24 |
all depends on your usage pattern of that disk to make an educated guess |
25 |
if that is true. |

The good thing about hard disks is that you can usually hear whether |
28 |
they are seeking or reading sequentially. If you hear a lot of seeking |
29 |
on sequential operations, it is time to reformat the partition or at |
30 |
least erase and recreate the affected files. |

Hope this helps, |
