I don't think so, because I scaned my HD and it had some major defragmentation, and I mean MAJOR!BrianSalts said:if i'm not incorrect, doesnt os x defrag your HD on the fly for you?
therefore, i dont think you need to worry about anything
ddekker said:just what did you scan you drive with to see it fragmented? Apples journaled file system takes care of it self, the only disk tool you have is "repair permissions" as far as I know
The OS automatically defrags commonly used files under 25MB or so (last time I checked anyway).pianoman said:Apple takes care of defragging small files but if you constantly work with things like movie files or even large pictures or large music files you probably should do a defrag.
i don't know the exact file sizes, but a google search should reveal the specifics. defragging, contrary to many OSX users' belief, is not always unnecessary.

mkrishnan said:This is really interesting. I thought that when files are downloaded in general, the data was put in a temp download file until you got the whole file, and then it was re-written into a new file in order to avoid this issue. Like how Safari makes a .download file until a file is completed. So this is not quite right? Are large download files in general susceptible to fragmentation? Or is this specific to Torrent?

disconap said:The part that I don't buy is that OSX needs to defragment files; the way Unix filesystems work is from the tree, not the space, so there is no searching, just a list of places the heads need to go to get the bits of files. I can see, when working with HD files, it just being too much for the drive, but in general defragging is unnecessary (and as was stated before, there is some minor auto-defragging that is part of the OS; this is why most people tell you to shut down your comp the minute you accidentally delete something, as the defragger and the RAM swapping can lead to it being overwritten very, very quickly).
