Some hard disks do make noises when reading data, others do not. I have had some that are easily heard, and they always were that way, and others that are silent. As far as backing up data, CDs are an option but with a lot of data that gets a bit inconvenient, maybe one of the GUI CD writer tools on FreeBSD makes spanning multiple CDs less of a performance. Maybe there is some tool to verify the CDs where written properly as well. I hope. I have another computer that I just copy the data to. Some people just install two hard drives inside their system and use the second as a backup. Some people use external USB hard drives. -- A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.

Correct? Not really. Rather than trying to keep an entire file contiguous, UFS just keeps reasonably large blocks contiguous, and all of the blocks in the same part of the disk (cylinder group). The basics of this are all still the same as in the original research paper; see /usr/share/doc/smm/05.fastfs/paper.ascii.gz. Also bear in mind that the term fragmentation is used to mean something different in the Microsoft world than it is with respect to Unix filesystems. I have commented on that before on this list; please see the archives to avoid repeating old discussions.
