Confusing Boot Problem
 
Hi,

If anyone can help I'd really appreciate it.

I have made a full clone of my Macbook Pro's internal HD. I'm running OS X 10.5.7. The clone drive is a Lacie Rugged 500gb external drive. It supports firewire 800 which is what I'm using. It's been formatted in Mac OS Extended (Journaled).

When I first ran SD it made the clone no problem, I did "back up all files" and requested it restart from the clone, which it did. Superduper! It works.
Since then I've tried to boot from it again but to no avail. I've tried holding down the option key on start up but it just boots into my Mac HD and when I've tried to select it from startup disk in system preferences it just won't show up :eek:

Hope that's clear.

Thanks
Sam

Holding down Option at power on doesn't give you the startup drive picker? It should... perhaps you're not holding it down enough?

If it doesn't show up in the Startup Disk Preference Pane it's very likely mispartitioned. It should be GUID - see the FAQ.

Problem solved
 
Thanks for your help. I reformatted GUID and it showed up in start up disk pane. Still couldn't get it to appear using the Option key though. I found out that on UK systems you hold ALT and not Option to get to the boot selection screen.

Cheers

That's interesting: on my keyboard Alt and Option are the same key (two labels).

Shows as startup, won't boot
 
I can choose the SuperDuper clone as a startup disc in Sys Pref or in the Startup Mngr, but the computer still boots up from the the original volume.
(Startup Mngr does pay attention when I choose the TechTool edrive)

I'm running 10.4.11 on a 2.8GHz Intel
Iomega has always been a reliable Mac Hard drive for me.
I don't know what the chip set is.

DriveGenius2 confirms the Iomega HDD is in perfect condition
Renaming the clone the same as the original volume made no difference.

The drive should be partitioned as "GUID", Gingau, not Apple Partition Map... that may make a difference here.

Guid
 
Dave

You mentioned in this post that this was in a FAQ, but I could not find which one.

OK, Now I see that in Disk Utility under partion/options when choosing the drive rather than the volume.

I had read through the SD user's guide and this is not listed in "Prepare for your backup"

Thanks. I will try the process again.

dnanian 05-25-2009 04:47 PM

True: GUID wasn't an option when the current version of the User's Guide was written. That's why I put it in the FAQ... a bit of a runaround, I know.

Gingau 05-26-2009 09:12 PM

Success. Thanks for your personal input.
The Clone is working perfectly.

Could you clarify which FAQ the GUID requirement is mentioned for future reference?
Muchly Appreciated
Gingau

Yes, it's in the "I can't boot from my drive" FAQ. (It's also in the Time Machine FAQ, as I recall, and is likely elsewhere, too.)
