carlor Level 1 Level 1

I have a quite odd issue. Time machine and my time capsule worked perfectly when at some point automated backups failed with a permission error. Interestingly I still was able to mount the disk and volume manually (i.e. through finder) and read and write to it.

After trying some non intrusive procedures I finally decided to delete the sparsebundle and to start from scratch. The data wasn't important at this point. So I tried to change the volume... however the exepected window doesn't pop up instead /var/log/system.log shows:


System Preferences[242]: *** -[NSCFString substringFromIndex:]: Range or index out of bounds


So I removed the time machines preference file but I still not able to bring up the window to select a different volume.


How can I fix this?

    Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.


    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)


    Any change?

    No still the same. As said I can mount the volume and  copy stuff onto it, so doesn't look like a permission problem. I think the issue here is that time machine doesn't allow me to change the volume. When I klick on "Change Volume..." a window should appear but this doesn't happen. Instead


    System Preferences[242]: *** -[NSCFString substringFromIndex:]: Range or index out of bounds


    This error message sounds like the application trys to access an array with an incorrect index.

    Yes it is, but you got rid of the .plist for TM right?


    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
