Q: Disc Utility won't repair permissions on one of two partitions on an external drive

Running Snow Leopard  (OS Xv6.8) on a late-2007 MBP that originally ran Tiger.  I use Carbon Copy Cloner to maintain bootable clones for both Snow Leopard and Tiger, which are on the same LaCie D2Q 360GB drive, each in its own partition of ~ 180GB.  I recently set up this arrangement and both clones will boot.

 

I had some errors* cloning Snow Leopard to this drive yesterday (though it cloned without the errors today) and ran Disc Utility just to clean up anything that needed it.  No problem with Disc Repair on the whole drive or Permissions Repair on the Snow Leopard Clone partition, but Disc Utility grayed out the Permissions Verify and Repair options when the Tiger clone partition was selected.

 

I don't know how to begin thinking about this.  Is the Tiger clone something that Snow Leopard's Disc Utility won't bother with?  I thought Disc Utility was just about disc formatting & function, independent of content.

 

Any ideas?  I don't have a problem with the Tiger Clone, just keep it for the odd unforeseen disaster, and I do have it cloned on another drive as well.

But it would be nice to be able to use the Snow Leopard Disc Utility on the whole drive...

 

Thanks,

Sharron

 

 

*The cloning errors involved one file that CCC couldn't get infornation from, an Apache file having to do with configuration.  GOK what that means!

A:

You cannot use the Disk Utility that came with Tiger or the one that came with Leopard to repair permissions on the other OS. You use the Leopard version on Leopard systems and the Tiger version on Tiger systems.

    Thanks, and duh!

     

    I just spotted a previous thread that made this point, checked back to amend the question, and there you were!

     

    So Disc Repair is OS version-independent, but Permissions Repair is not, right?

     

    I already knew Disc Repair couldn't fix a dropped drive that was making loud clicking noises....

    Permissions repair is very much OS dependent. You should repair permissions while booted in to the OS and use DU in that OS to repair permissions. Don't use the installer discs for permissions repair, as update to the OS may have changed some permissions.

     

    Incidentally, Snow Leopard in particular will throw up a long list of repairs, including one that won't be repaired. These items will still show, no matter how often you run DU. http://support.apple.com/kb/TS1448

    I have an external hard drive that I suspect needs permissions repaired.  I don't even know what OS it was originally formatted in, or if I still have a computer running that OS.  Currently, every computer I put it on does not offer me the opportunity to repair the permissions.  How do I fix this?
