The only way I could possibly see defragging often being bad, is if you have a SSD. The amount of disk usage used by defragging is unlikely to wear out your drive any more than normal usage.
Windows defrags in the background anyway, even when not scheduled when disk usage is idle, so that could account for some of it, maybe you are checking at the wrong times?
Also, in my opinion 3rd party defraggers do more harm than good. The Windows defragger is Prefetch and Superfetch aware, so it orders the files the way they are needed. 3rd party defraggers dont always do that, and can actually defeat the object of superfetch, as the drive spends more time fetching.
For example: When you launch an application, lets say it reads the first 10KB of notepad, then the last 5KB of Media player. (yes I know... an unlikely scenario, this is just an example) Windows defragger will put the files in that order, so they can be read quicker. A 3rd party defragger is much more likely to put all of notepad together, and all of Media Player together. This actually results in longer seek times because it has to go and find the other bits, and then go back again, even though technically
the programs aren't fragmented any more.
