Eddie G. - I really never found a need to defrag at all since I started using OS/2 back in the late '80's. In fact, that calculation was first performed to show that the IBM OS/2 HPFS filesystem did not require fragmentation either. I have never used Windows as my primary operating system so fragmentation was never a problem for me except on DOS with FAT.

HPFS, like most modern filesystems, was designed to allocate space using algorithms that reduced fragmentation to negligible levels. For HPFS and EXT2/3/4, I have measured fragmentation at levels so low as to be irrelevant to most application environments.

I did, however, experiment to a couple defragmentation programs for HPFS on a test machine back in about 1991 or thereabout. It made no noticeable difference in performance and took about four hours to do the defrag. I never trusted defrag programs and always shudder when friends say they do it frequently on their non-Linux computers.

Thanks for your comment. - and thanks to all who have commented on this article.

I found the BIOS configuration very inconsistent. Some booted my Live USB right away with no changes and others needed some minor changes to boot. II never did get some to boot to the USB, but I probably just did not spend enough time fussing with the various config options. Nor did I have the directions that might have given me some clue as to how to do so.

But the key is to try. Any computer that I cannot figure out how to boot to a USB device fairly quickly is probably not going to be on my short list anyway, unless it has some whiz-bang feature that I just cannot live without.
