There is a defrag package: Package: defrag Version: 0.73-1 Priority: extra Section: admin Maintainer: Adam Heath [EMAIL PROTECTED] Depends: libc6 Architecture: i386 Filename: dists/stable/main/binary-i386/admin/defrag_0.73-1.deb Size: 290134 MD5sum: 7e9084be2707e6e68bab23332ee7e465 Description: ext2 minix xiafs file system defragmenter As a file system is used, data tends to become more and more scattered over the disk, degrading performance. A disk defragmenter simply reorganises 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 more efficient. installed-size: 715 Torsten

Real fragmentation percentage always less than or equal to reported one, and i don't know how to get the real one reported. I might be very wrong though...

I have an 8gig hard drive which I made a single ext2 filesystem to hold my mp3s. While ripping and encoding some of my CDs, the fragmentation jumped to 45%, so I figured it was time to defrag.
