Title: Leopard problem with external firewire drive.
Post by: gunug on November 28, 2007, 09:48:42 AM
New 20" Dual-Core iMAC's came in the door here and I'm charged with trying to make them work with a dual operating system deal because a lot of the music software they want to use is for XP.  Now I backed up the original 10.4.11 OS onto an external firewire drive and I took the time to make it bootable on the Intel by reformatting with GUID (?) and now I find that the 10.5.1 OS on the system on the iMAC will not see the firewire drive where it could before I updated from 10.5 to 10.5.1.  Has anyone else seen this kind of thing?

Later: I rebooted the 10.5.1 on the iMAC in Safemode and it saw the firewire partitions and then rebooted it again in normal mode and it still sees them and their contents!  Weird stuff!  Also what does it mean when I try to to restore an image from one of the firewire partitions and it fails and says:

Could not find any scan information.  The source image needs to be imagescanned \ scanned for restore

Just yesterday read an Apple tech article about external drives not showing up or being recognized after upgrading to Leopard. The 'solution' was to simply wait a few minutes (up to 15!) and things would 'settle down'. It seems that it takes a while for the OS to finally 'see' those drives and convince itself that they are not illusions! laugh.gif

As I understand you post, the drives are now visible/usable? So, how long did you wait that first time? Thinking.gif wallbash.gif

I'm sure that it was more than an hour but I never saw the external drive until I rebooted in "safe mode" and then I could see it.   About the 2nd topic; there are modes/options of the Disk Utility that are disabled unless you type the following into TERMINAL:

defaults write com.apple.DiskUtility advanced-image-options 1

or installing XCODE stuff from the DVD!

The 'defaults write' method seems to be the latest way to change/edit settings in Leopard, don't remember seeing much of that in Tiger. dntknw.gif But do you know of a source for all the files/apps/value pairs and/or what they actually do? Maybe at Apple's Dev section.

XABD - I don't know of a "MASTER" List but will keep my eyes open!  On my problem: I've elected to zero the iMAC drive out and reinstall 10.4 and try, try again!

Naturally, I didn't copy the Apple Article number but it's title is "Installer destination window does not show drives."

The "solution" is to "wait a while"! It also says that the larger the volume, the longer that "while" may be. smile.gif

As an "advanced" solution, they suggest doing an fsck 'status check.'

In Terminal, execute the following command:
ps auxww | grep fsck

I have no idea what that does, I thought 'grep' was a tool used to find/change text! dntknw.gif
