Complete Optimization of the Startup Volume 26 Mar 2016 16:06 #7101

Okay, I was wondering how to go about rebuilding the startup volume on my iMac. To make certain everything is hunky-dory I figured I’d:

1. Rebuild the Startup Volume
2. Initiate File Optimization on the Startup Volume
3. Initiate Volume Optimization of the Startup Volume

What’s the best way to proceed?

You have the three steps you posted in the right order. Before you begin, you should:

1. Make a complete backup of the startup volume, using a utility that can make bootable backups.

2. Run the Surface Scan test to check the device containing the startup volume for unremapped bad blocks, one of the two most common causes of failed optimizations.

3. Boot from another volume and run the Volume Structures test to check the usual startup volume for disk directory errors that exist before the start of the optimization, the other most common cause of failed optimizations.

4. When the optimization is finished, run the Volume Structures test again, to make sure the optimization did not introduce any disk directory errors.

So basically, in order to optimize the startup volume I can startup this machine in target-disk-mode and connect it to my other machine, allow it to mount and optimize it?

Yes. You can do the File Optimization (which should be done first) without changing to another starttup volume, and then do the Volume Optimization while booted in target disk mode.

Can I load TechTool Protogo onto a thumb/jump drive and boot from that and run the optimizations? I have an external firewire drive that I might be able to use as well.

You would have to create either an eDrive or a Protogo device on the USB memory stick to do that. For an eDrive, the minimum size is 32 GB. The USB memory stick should be formatted by Disk Utility to have a GUID partition map and a single Mac OS Extended (journaled) volume.

What about protogo on my external firewire drive and then run the optimization from there?

If you have an external FireWire drive that you can afford to erase entirely, then you can make a Protogo device on it. The Protogo installer completely reformats the entire device, removing all of the original volumes and their files.

That wouldn't be a problem www.micromat.com/components/com_kunena/t.../emoticons/smile.png

The program that makes use of a device you supply is called Protogo. Protégé was a FireWire USB memory stick that we offered while such devices were available. I might even be able to find mine.
