In general fragmentation only happens when you do many deletes and
writes on a disk that is nearly full.

Package: defrag
Section: universe/admin
Description: ext2, minix and xiafs filesystem defragmenter
As a file system is used, data tends to become more and more scattered
across the disk, degrading performance.  A disk
defragmenter simply re-organises the data on the disk, so that
individual files occupy a single sequential set of disk
blocks, and all the free space on the disk is collected together in a
single region. This generally means that reading a
whole file is faster, and disk accesses in general are more efficient.
