Disk Utility problem after cloning

I have G4 1 Ghz iMac, 512 MB RAM. OS X 10.4

After installing Tiger on internal HD, everything seemed to work without any problems (but don't ask me about Spotlight!).
I then set up my External LaCie D2 Firewire 400 HD with three partitions:
1. Backup: a partition for backup of Documents and other User files using DataBackUp 2.0.5;
b. HD Clone: bootable 'Backup All Files" clone of internal HD created with SuperDuper! 1.5.5;
c. Startup Clone: bootable "Safety clone - shared users and applications" created with SuperDuper. I use this as my startup disk.

When I startup up on my Internal HD and launch Disk Utility to repair permissions and repair disk on the partitions on the External Firewire HD, no problems reported with any of the partitions

If I start up on the Startup Clone on external HD and run Disk Utility, I can perform the Repair Disk function on the other two partitions on the external hard drive. However, when I try to Repair Disk on the Internal HD, a task which always worked prior to installing Tiger, I get the error message: Unable to Unmount Volume - the first step of verifying and repairing a disk. The reason for this failure appears to be an open file/application on the hard drive.

The same problem occurs if I boot from the External HD Clone (i.e. the complete clone).

The same problem occurs if I boot from an eDrive created with TechToolPro 4.0.4 on its own partition on the external firewire drive. Disk Warrior on the eDrive also fails to unmount the internal HD.

However, it I boot from a bootable CD or DVD containing Disk Utility, then the latter functions without any problems and fails to find anything to repair on internal HD. Can also repair internal HD by launching it as single user and repairing internal HD with AppleJack.

There seems to be a problem with the cloning process with both SuperDuper! and TechToolPro such that Disk Utility (and Disk Warrior) act as if there is an open file/application on the internal hard drive when the startup disk is on a cloned drive on an external firewire drive.

The following did not correct the problem:
1. Disabling Spotlight via terminal use of mdutil and deleting .Spotlight index files from all drives;
2. Disabling Dashboard by quitting Dock.

Any suggestions?

You should be able to see what file is actually 'open' on the volume using lsof. Try the following:

- Boot from the clone
- Open Terminal
- Use the command:

lsof | grep "internal-volume-name"

That should tell you who/what is holding the drive open...

It looks as if there are a lot of files on the internal hard drive that are open when I boot from the clone. I have attached the Terminal output text file of
lsof | grep "internal-volume-name". This seems to be a problem unique to Tiger as it never happened with the OS 10.3.9 and earlier versions.

Given that, are you sure you're not running from a Safety Clone, as opposed to a full "Backup - all files" clone?

If not, try naming the backup the *same* as the internal drive, smart update it, and then boot from it. (I explain elsewhere on the forums about aliases resolving using the volume name...)

My startup disk is a Safety clone. I also have a "Backup - all files" clone. WHen I startup from the full clone, I get the same error with Disk Utility and Disk Warrior run from the startup disk. Since Disk Utility is not aliased to the internal drive on either the Safety clone or the full clone, it should not be aliasing the DU on the internal drive. The same problem occurs with the eDrive cloned by Techtool Pro.

For reasons beyond me, only my internal drive shows up on the desktop. None of the partitions on the external fire drive show up on the desktop. I did not realize they were not there because I have Finder Preferences set not to show the disks on the desktop since I can access them via DragThing or via a Finder Folder where they all show up. The desktop appears to be only place I can try to rename the Safety Clone, short of recloning it with same name as internal drive, if SuperDuper allows that.

For what it is worth, I attached the output of open files when I booted from the Full Clone. It is much smaller.

Well, the Safety Clone is always going to have a lot of files opened on the original drive, because those items are shared. So that's normal.

But, the "Full Clone" is likely doing this because it's not named the same as the original "Macintosh HD" -- try that, Smart Update it, and I think it'll be resolved.

Disk Utility/Disk Warrior aren't causing the problems as such -- these other items that have auto-started on you are... and those are starting from the original drive, due to the naming & aliases (these are internally stored aliases, not ones you create yourself).

I can't explain the eDrive because I don't know how exactly they do what they do... sorry.

Hi, lstuff.

Choose the source in the first pop-up, the destination in the 2nd, and "Backup - all files" in the 3rd.

(Let me suggest that you check out section 3 of the User's Guide, too. That has all the details.)
