Speed Disk safe?
Authored by: BruceM. on Apr 26, '02 01:19:34AM

I must say that I have used Speed Disk (not System 2.0) at least 30 times on OS9 systems and now at least 15 times with OSX, without ever experiencing the slightest problem or worrisome idiosynchrocies. Maybe its dumb luck or I'm tempting fate, but some things I always do before Speed Disk is to run Disk Warrior and TechToolPro first, never use Disk Doctor (that one does seem to be flakey, often wanting to reverse TTP repairs) and to optimize often, rather than infrequently as fragmentation grows large. I'm aware that some believe optimizing/defrag to be unecessary or even counter-productive with Unix, but I always see a performance boost after, even if modest at times. Stable, no quits and fsck - y never detects errors either. Of course, everything is always totally backed-up with a mirror system at the ready, just in case, so I can continue to experiment freely.

Speed Disk safe?

I, too, have used Speed Disk a dozen times or so on my OS X system disk, with no apparent ill effects.
As has been said, avoid Disk Doctor and use Disk Warrior. I have had Speed Disk tell
me that it could not optimize my drive because of corruption immediately after running
OS X Disk Repair on it. I ran Disk Repair again and i found no problems. Then ran Disk Warrior,
and when I tried Speed Disk again, it ran without complaint. So DW fixes problems Disk Repair does
not even see.

As for the profiling trick with Speed Disk, it seems like it ought to work. The only criticism of Speed Disk I have seen is that it does not give good placement to OS X files, and that's what the profile does. I am giving it a try,
because if I can get decent results with Speed Disk I will definitely choose it over Plus
Optimizer, because the latter takes four or five times as long to optimize a disk. I had never
tried using the Profile Editor program before. It was not very intuitive, and took a good
deal of clicking on menus and things to find the ways to set things. Then, in Speed
Disk itself, the way of accessing the stored profile wasn't apparent either! You have to explore
sub-menus to find the way to "Add Profile", and then to choose it from the list once
you've added it. But having done that, it worked fine.
