Hi. Having a problem with an external 2TB HD connected to my iMac 11,2 running 10.6.8. The external was originally connected to a MacBook Pro (same OS) which failed and was replaced by the iMac about a month ago. The external has 3 partitions: Time Machine backup, Carbon Copy Cloner backup and a storage partition for image files.
I used the Time Machine back up to transfer files to the new iMac, re-cloned the whole drive to the CCC partition and added some new files to the storage partition. Everything has been fine until yesterday. I realized I hadn't turned on Time Machine yet to start backing up the new iMac. I selected the same Time Machine backup partition I had been using w/ the MacBook Pro as my Time Machine backup drive for the iMac, but all attempts to back up failed. Got this message:
Time Machine could not complete the backup. An error occurred while creating the backup folder.
Now when I turn on the external HD I get a message saying that the Storage volume can't be repaired and to back up the files from it. If I run Disk Utility it cannot unmount any of the volumes and can't initiate any repairs. Trying to fix disk permissions would fail on the CCC volume until 30' ago when it started displaying a long list of error messages. it's still doing it. Most of them start off with:
Open error 16: "Resource busy" on System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/ (this part here changes for each line).
And then the others begin with:
Open error 1: "Operation not permitted" on System/Library/frameworks/Python.framework/Versions/2.5/lib/python2.5/test/test _set.pyc (with some variation at the end)
When this list started running in Disk Utility, the Console displayed the following:
Cleaning up expired diagnostic messages database at path: /var/log/DiagnosticMessages/ 2014.05.28.asl
Disk Utility just finished with a bunch of lines that start off w/ either Unable to set owner and group on … or Unable to set permissions on ...
I can still display the contents of the volumes in Finder and I'm able to access the files but I can't work w/ the volumes themselves as explained.
Any ideas anyone?
