iDefrag and boot disk

[lavrishevo]

My question is how can I make a boot disk so i can run iDefrag on my main HD? I tried booting from the os x cd but only get the options to re-install or repair drives. iDefrag is installed on my main HD which I want to perform a full defrag on but can not while it is mounted, locked/in use, or whatever the hell it said. Any ideas?

Hi

theres two options

1. use superduper! or carbon copy cloner to make a clone of your mac onto an external disk. then boot into the clone by holding option on startup and selecting it in the EFI boot loader. then use idefrag while booted in the external clone.

2. download corolis cd maker which makes a bootable cd with idefrag on it. again use option on startup to select it in the EFi boot loader.

when ever you defrag, partition, or repair a hard disk you must not be booted in it.

you made a good choice using idefrag. many people say macs dont need to be defragmented. but doing a full defrag halved by boot time and i now get 7 cog spins.
