The longest drive took 50 seconds, and includes several compressed files which are more complicated to analyse because of all the way the compression works. When I did a review of <a href="http://donnedwards.openaccess.co.za/2007/05/great-defrag-shootout-x-diskeeper-2007.html" rel="nofollow">Diskeeper 2007 Pro Premier</a> ($99) it took 12 minutes to analyse the same system. Clearly this will vary from one machine to another. I suggest you send a detailed log file to Jeroen Kessels in case you've found a bug.

Diskeeper is a LOT faster. Anybody experience the same thing? Never waited so long to have my disk analyzed. It's a 320 gig drive with 100 gigs available.

Yours is 74% EMPTY. See <a href="http://donnedwards.openaccess.co.za/2006/07/why-i-uninstalled-diskeeper.html" rel="nofollow">Why I Uninstalled Diskeeper</a>. I think JkDefrag is brilliant! Much better than DK and not overpriced either. Check out the JkDefrag GUI and easier install utility at <a href="http://www.emro.nl/freeware" rel="nofollow">http://www.emro.nl/freeware</a> as well.

Having run Diskkeeper since the old NT4 days on servers, I know it's a decent defragmenter. I bought Perfectdisk because at the time I was looking for defrag tools, it's trial ran stable and did well. I saw no diff between it and Diskkeeper or O&O defrag as far as defragmentation quality, Since I was going out of pocket, I voted for PD 8 with my dollars. It was not as expensive and did the job. As far as 80% full disk, I think that's a non-issue, because it's hit or miss anyway. Some defrag tools will spot the smaller files first and move them, whereas if the other reads from a different part of the drive it may not see them. I don't defrag on an 80% full disk because of the risk of data loss, processor overuse, etc. If I have a near full disk, I simply move off files until I've cleared enough space for the defrag to run efficiently. Once you've defragged an overly full drive and killed it you won't make that mistake again. Of course YMMV.

You can't expect me to make things up. I have my CPU resource utilisation set to "normal", which is the default setting, and it works fine on my 1.46GHz Celeron M processor. By comparison, DK took 15 minutes just to analyse my drive, which is diabolical. I consider DK over-hyped because it *claims* to be able to defrag a drive but as soon as the drive starts getting full all bets are off, yet there is no warning to consumers about this. They have to discover this for themselves. It's embarrassing having to explain to a customer who has just spent $299 on DK Server that actualy it doesn't work because the server drive is 80% full. See http://donnedwards.openaccess.co.za/2006/10/perfectdisk-another-before-and-after.html JkDefrag 3.16 and PD8 both work fine on this particular server, but DK doesn't.

As you say, everyone has their opinions. If you test them side-by-side and go in depth to when a disk actually gets defragmented, you'll find (at least I did) that resource consumption is very close, and you can automate PerfectDisk. I've used both, they're both okay if you want to pay for a defragger, which many don't. Diskeeper and PerfectDisk are both decent. As you say, everyone has their opinions.

Looks like he is excessively critical of Diskeeper. Its not the 'overhyped' product that he makes it out to be. Infact, in his review of Perfectdisk, he gives it high marks without taking into account its shortcomings as a CPU hog, a lousy UI, its lack of intelligent tasking and its lack of an automatic defrag mode . Reiterating my earlier point, everyone has their own preference when it comes to any software, and IMO, perfectdisk has some severe usability issues that Diskeeper does not have. Anyway, I think home users are only a small segment of the defragmentation software market. Most of the business is in the commercial sector, where AFAIK, Diskeeper has a huge lead over its competitors. Don't recall the numbers, but I think it was 90% or so.
