On all my systems and every custom install I do for others, I always create a 20-30GB partition and call it Repair HD. It gets a stripped down install of OS X, and I have them buy a copy of DiskWarrior to keep on it. Even to run Disk Utility properly you should be booted from somewhere else, yes. This setup has saved my butt soooo many times, and those I do it for. They can't believe Apple doesn't do this by default. It makes troubleshooting and maintenance so freaking easyl

Guys, I've found contradicting information about the Repair Disk routine (fsck).

It is always said you need to either, boot from your installation DVD or in Single User mode to use it.

What I want to know is, can I simply boot from another volume (a clone of the main system in a different HD) and run it from there safely?
I read that was not recommended, but I don't see why not, and I don't think I trust the source of that info...

Thanks!


Is this your source?

Personally, I would trust it.

.

Actually, CutTime, that link just confirmed my suspicions: that it is perfectly OK to run the Repair Disk utility from a different volume.

I was not certain of this because most sites only mention doing it by booting from the installation DVD or using Single Mode. And I found one that actually recommended NOT doing it from another volume (which now I know that claim is unsupported and wrong).

Thank you for the link, and Andy for confirming what I thought is OK to do.

Absolutely. I make the partition in TechTool unless I have my Time Machine drive connected directly - then I put the partition on it. I keep TT, Disk Utility and Disk Warrior on the partition.

I have never actually fixed anything with TechTool or Disk Warrior but I understand it can be done. They are very good diagnostic tools, however, and I find them useful. Disk Utility does repair things on occasion.

Apple released another Java upgrade for Lion yesterday. With the 4/3/2012 release, my track pad was too jumpy to use in a browser and I went back to my track ball - still jittery but I could get my work done. That has been fixed.

I think that troubleshooting your Mac can be done easily. There are not much components that need to be checked as you can pretty much see everything with the use of built in tools.

It does not act like the device manager of the windows OS as they have clearly defined each component and what it is going to do unlike on a win7, you would need to be able to present the proper drivers to go with it.

My two cents:
Create a clone of the main partition on an external FW HD, with SuperDuper.
- Can be used to repair anything on the main partition
- Can boot just like the main partition in case of HD wreck, specially when on a deadline.

Creating a clone with SuperDuper used to be my preferred method of maintenance and backup. OS X 10.9, however, installs a second partition for maintenance by default which you will have to use if you encrypt your entire hard drive with FileVault 2. I still prefer the SuperDuper method but have gotten used to using Time Machine for backups which makes it a breeze to transfer your existing data to a new virgin install of OS X whenever a new OS X version is released.
