QotD: Fragmentation

Question: Do you defragment your hard disk(s)? Regularly? Ever?

My Answer: Never. Though erasing, installing a new OS, and drag-copying my old files back over is a pretty effective way of doing so. Then today I read this:

While we're talking about the not so well known/hidden new Panther
features: while digging through the kernel sources i've found a quite
amusing new feature built into HFS+. Namely automatic file

Everytime an application opens a file for reading, HFS+ checks if the
file is fragmented and is less than 20MB in size. If so, it copies the
file's contents to a continuous region on the disk and frees up the
previously allocated blocks.

Even less reason to defrag, I guess. Some of my Windows-using friends defragmented every day!

You are encouraged to answer the Question of the Day for yourself in the comments or on your blog.

  3. Defragment?

    I have never defragmented my iMac's hard drive in the nearly two years that I've had it. No performance degradation, no disk errors. If it ain't broke . . ....

    I realize it's not exactly what you're looking for, but here's the post in question.

  5. I defrag every 3-6 months although sometimes I slack and avoid it for a year or so. I do it more on Macs than PCs, not out of necessity, but because I care about my Macs more... heh.

    While waiting for my own copy of Panther, I am, of course, reading reports on Panther carefully. Beyond the usually flashy stuff with little substance that comes out on mainstream
