THE LIMAC FORUM/MAY 2009

you delete some files to free up more space, but Photoshop still

complains. This is because Photoshop needs contiguous free

space, and your free space is scattered around the hard drive.

Even everyday people can take advantage of a defragmented

large file. My Microsoft Entourage (email) database is 5.57 GB

and fragmented. It takes a fair amount of disk accessing when

I do a search. You can see a pause as you scroll through your

Microsoft Word file you’ve been working on for 20 years.

You cannot properly optimize the free space on your drive

while you are booted up off it, so you need to boot either from

another partition or drive with a System on it, or the CD/

DVD that one of the utilities comes on. As I’ve said Apple

doesn’t include any software for this task, so you have to buy

either the $35 one-trick iDefrag from Coriolis Systems, or

the defragment function of either Micromat’s TechTool Pro

5.0.4 or Prosoft Engineering’s Drive Genius 2.1.1 or Intech

Software’s SpeedTools Utilities. (I think Intech is out of busi-

ness now.) Some of you may be familiar with TechTool Deluxe

which comes with a AppleCare Protection Plan, but that limited

version lacks this and many other functions of the Pro version

(which you can upgrade to for $59). Folks with much older sys-

tems used to rely on the Speed Disk application part of Norton

Utilities and the SystemWorks bundle. Switchers to the Mac from

Windows are surprised to not find a defragmentation program,

as Windows has had Diskeeper since Windows 2000. Microsoft

licensed it from Executive Software as it was the most popular

third party program of this type back then. Norton’s SpeedDisk

also was popular.

The optimization process, if interrupted, could ruin

your data, so make sure you have a complete backup with

SuperDuper!, Carbon Copy Cloner or Time Machine first. Some

of these programs have two different procedures, one for file

fragmentation which combines all the various segments of each

file into one spot on the drive and another for disk defrag-

mentation which combines all the files into one block so that

the free space is now in a second contiguous block. This is the

second step that may be most important to Photoshop’s needs.

In any case, you would probably be booting off the utilities

CD or DVD and optimizing your startup disk. You should use

one of the suite’s directory repair functions first and then per-

form the file and disk optimizations. With many terabytes of

data, this will take a very long time, so be prepared to start this

before you go to sleep.

Would you advise the average web surfing and email kind

of user to not defragment since the potential for disaster is

so great? It seems a lot of switchers from the PC realm were

indoctrinated to doing this regularly.

■ No. Heck I don’t do it regularly. I’d guess the average non-

switcher is not aware of the minor problem and doesn’t want

to know. Of course many basic users don’t have a backup of

their files and even more don’t have a battery backup or UPS

to keep their computer alive and well and their data safe. With

no included software from Apple, they assume it is not required

and leave the issue at that. I don’t recommend periodic defrag-

menting to most of my clients in that class. The graphic art-

ists and video folks know about fragmentation and will fix it as

needed, maybe once or twice a year if they are very concerned

about the issue. With disk capacities and CPU speeds as they

are nowadays, it’s less of an issue then it once was. Even if you

have a disk and a battery backup and there were no bugs in the

defragmenter software, the speed improvement to be gained is

usually not worth the time to run the software.

I have a 2.8 GHz iMac. Can it be used a server?

■ Yes. You can install Mac OS X Server software, replacing

the normal client version of Mac OS X or you can leave the

client version, use the personal Web Sharing function from

Apple or install any of the dedicated web server applications

like Abyss Web Server, Apache, LiteSpeed Web Server or Roxen

WebSever. The oldest (since 1995) http server for the Mac was

StarNine’s WebSTAR, which became 4D WebSTAR Server

Suite and then Kerio WebStar and discontinued last year. I’d

say start with what is free and there already with the included

Apache 2.2.6 server and the PHP 5.2.6 server. read this out-
