JetDrive Defragmentation Suite

<< < (4/5) > >>

johnk:
It turns out the hard disk was badly fragmented -- the 10 most fragmented files averaging more than 20,000 fragments each! In fact it was so bad that XP's built-in defragmenter wouldn't work. I tried it a couple of times, and it just played with the files but didn't fix them. Just kept reporting that I still needed to defragment my disk!

I turned to JKDefrag, and it did the job. It took 12 hours, but it worked. So yes, in my experience, an occasional defrag is probably a good idea and yes, if your disk is in a bad way, trying a specialist program like JKDefrag is worth a shot.

Scary!  :tellme:

I'm guessing that this drive partition was pretty full, with something like less than 10% freespace available?

The scary thing was I had 35 per cent free space, and the XP built-in defragmenter still wouldn't defrag the files.

I used my DiskTrix UltimateDefrag_3 to defrag my D drive. After a successful job, I ran the program again, just to make it analyze and display the drive's state. I liked it, I thought it was all blue = all defragged.

Then I installed and ran JetDrive Ultimate 5, and had it analyze the D Drive. The answer was something like "oh my god, is this your drive? Defragmentation is highly recommended!"

I didn't bother to test how well or not it would defrag. I just uninstalled it.
But it sure was a nice program to look at!

Yes, I am aware, there are different ways to defrag. What is order to one program, may be disorder to another one. My problem was that JetDrive doesn't speak about such advanced problems, it just shows 3 levels of need. JetDrive is not just "easy"; it is too simple!

f0dder:
There's, basically, two major parts involved in defragmentation:

1) getting a low amount of fragments per file; the "core" of defragmenting.
2) managing file locations on disk: consolidating free space, "optimized" locations.

Different defraggers will disagree on what "optimized" means - which is why, even for a all-files-in-one-fragment and all-free-space-consolidated filesystem, two defragmenters might want to completely rearrange your files.

How much rearranging matters depends on your system, disk access patterns, and religious beliefs; as long as you keep large files in a few fragments and your MFT defragmented and with room to grow, things will be OK :)

Just out of curiosity, do you know which file had 20K worth of fragments. Some sort of database? Or was it your pagefile or MFT?

Reason I ask is because I've never had anything to remotely with that monster of yours. And I handle servers and multi-user environments where some files get clobbered and frag up pretty badly in the course of a work week.

Always something new for me to learn about.

I've been running PerfectDisk Pro for a few years now. To be honest I wondered about the need for a stand-alone defragger in Windows 7 also, but PerfectDisk charges me a maintenance fee of, I think, $8 or 10 every two years to be entitled to all upgrades so I have just paid that and kept right on using it. Don’t know if it really helps but I am definitely defragmented all the time!!
