First of all, please allow me to state that I've been using Diskeeper Pro Premier for a few years and I actually like the product. From my experience, it does an overall decent job, is unobtrusive when running in the background, manual defrags are very quick, and I-FAAST works as advertised (or at least *appears* to do so). However, I am absolutely and thoroughly disgusted with the activation scheme. I've done quite a few image restores (to the same and new HDDs using Shadow Protect) and Diskeeper is the **only** program I own that requires activation after restoring an image (all the other programs I use that require activation have never asked me to reactivate after a restore). But NOW, after my latest restore and the (as per usual) Diskeeper activation routine, the program is bluntly informing me that I've basically 'activated too many times'. Thus, I own a 99 dollar software product that is currently useless; I can't even do a manual defrag as that option is greyed out. Quite frankly, if I believed the product was, without question, the best in its class, I would go through the hassle of contacting support, explaining the situation, and waiting for a response. But after reading a number of posts on this board (and others), I no longer believe that Diskeeper Pro Premier is the best defragger on the market. Moreover, even if it were, to my way of thinking it would sort of need to be roughly *twice* as good as any competing product since, after all, it costs over *twice* as much. I apologize for the lengthy rant but am seriously looking for advice from those who have used similar (commercial) products. I've read other topics on defraggers, including the links contained therein, and am leaning towards buying either PD2008 or Ultimate Defrag. I am, however, open to any and all suggestions provided the suggested products are full-featured, reliable, and reasonably priced (i.e., I really don't consider $250 for 3 Diskeeper Pro Premier licenses "reasonable" for this type of software). Thanks for reading and any thoughts on the issue(s) raised herein!
