Mac OS X 10.3 Defrags Automatically

Posted by pudge on from the hot-character-adaptive-respawning dept.

EverLurking writes "There is a very interesting discussion over at Ars' Mac Forum about how Mac OS X 10.3 has implemented an on-the-fly defragmentation scheme for files on the hard drive. Apparently it uses a method known as 'Hot-File-Adaptive-Clustering' to consolidate fragmented files that are under 20 MB in size as they are accessed. Source code from the Davwin 7.0 Kernel is cited as proof that this is happening."

    In my day, we'd crack open the drive on our Mac SE30s, sharpen a magnet on a whetstone, and defrag that sucker by hand.

    Kids these days. It's the MTV, ya know - makes 'em lazy.

      To defrag? Boy were you lucky--my SE hard drive had a crank to start it in the morning.

      Oh wait: that would have been actually useful. (What, nobody else remembers stiction?)
