If you believe all the Diskeeper marketing hype, then this is perfectly OK, but I just find it a tad annoying. See top image and then the one directly above. The display shows the file number instead of the file name on NTFS volumes, and PD insists on placing part of a large file in front of a reserved space, and the rest of it afterwards, ensuring that the file is fragmented.

DISKKEEPER LITE UPDATE

On the subject of annoyances, there are a few more: the screen display doesn't update correctly in the area where the defrag has yet to be completed.

DISKKEEPER LITE MANUAL

You have to suspend the 'screen saver' schedule, run the manual defrag, and then enable it again. The normal defrag kept getting cancelled by the 'screen saver' option, which is a bit weird.

The only time I got PD to interfere with anything was when I set up the 'screen saver' defrag option, and then tried to run a normal defrag. The defrag doesn't interfere with downloads in progress or eMule activity. I don't do this normally, because I tend to do defragging when I don't need to use the PC.

I found that I could run the defrag and do less disk intensive tasks, like blogging or writing program code while the defrag is in progress. You have to enable this feature and it does mean that the defrag takes longer. One of the nice things about this program is that PD will monitor the disk usage and scale itself back if the drive is being used by another process or user. In the meantime I figured out that I could create small registry files with the required settings, and make the changes to the registry from the batch file. Writing to the sales people did get a reply, however. I wrote to Raxco's technical support about this, but got no response.* I have yet to get any kind of technical response from them about anything. The command line option doesn't allow you to change the 'CPU Priority' so you can't have it set to 'Normal' or 'Idle' by default, and then change to 'Turbo' when you are running the command line. I scheduled a 'Free Space' defrag and a 'Smart Placement' defrag on alternate days, to ensure the best drive performance for this server. On one of the servers the defrag runs at 1am, when no one is using the system. If you don't like this idea you can also schedule defragmentation to happen during quiet times. The third good point is that PD has a command line option, so you can create your own batch files for special defrag needs.

One of the PDF documents on the Raxco web site makes a big fuss about PD's free space defragmentation, and I must say I have found it helpful, especially when I am working with large files. Sometimes this may mean a boot time defrag, other times it may recommend a free space defrag, depending on the status of your files. The second good point is that when you click ' Analyse' it will examine your hard drive, building up a display of the files, and then calculate the best way of improving the file layout to speed up your drive. I quickly switched off the extra help on the right, because it explained concepts I already knew, but unlike most help screens, this one was actually quite useful, especially for first time users. The first good point is that it installs without fuss, and the screen display is clear and useful. I have put off the review several times, even though it passes almost every test I can throw at it. It has been difficult writing this review, because I can't give it a 'first look', since I've been using the product for ages. But where it matters most, PD8 gets the job done, and it does it well, both on servers and workstations. It has some niggly quirks that I really wish the guys at Raxco would fix. That's not to say it is 'perfect': it isn't.

I can honestly recommend PerfectDisk to anyone who needs a simple defrag utility that just does its job as advertised without too much fuss. It worked fine right out of the box, and I bought a copy of PD7, which I later upgraded to PD8. It was only after my drive got to less than 20% free disk space that I discovered the first major problem with Diskeeper, and eventually tried PerfectDisk.

When I first started using Diskeeper Lite several years a go I wanted something that would work a bit better than Microsoft's built-in Windows Disk Defragmenter (WDD) and figured that if Microsoft had licensed their technology from Diskeeper (previous versions in DOS were from Norton Speed Disk) I might get an improved version from Diskeeper themselves.
