What is this sh*t? I thought I'd do a super-defrag on one of my backup drives, so I formatted the drive and then ran my backup program to produce a nicely compacted drive with no fragments. The backup program copied the files one at a time, in alphabetical order by directory, subdirectory, and file, took most of the night to do it.

The result was a nicely compacted disk with 70% fragmentation! (see the attached photo.)

How is this even possible? Did my backup program choose sectors pseudo-randomly based on astrological signs or something?

WTF.
