Hi All, My Macbook Pro is going into Apple Agents for attention tomorrow & I am trying to back up via SuperDuper to an external Hard Drive so I can wipe the main drive on the notebook before I hand it in. I have did a verify & repair permissions & then ran Super-Duper but in the keep getting a message - "Failed To Copy Files From Mackintosh HD To Macbook Pro Super-Duper Back- Up". I am very novice level but having looked at the very long log, at the end in red there is the following: "10:06:40 AM | Error | SDCopy: Error copying compressed /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/share/ri/1.8/system/REXML/SAX2Listener/xmldecl-i.yaml to /Volumes/Macbook Pro Super-Duper Back-Up 1/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/share/ri/1.8/system/REXML/SAX2Listener/xmldecl-i.yaml of type 8\n: Input/output error" I am not sure but I think it is referring to a folder called "Ruby.framework" - no idea what it is or what it does! If need be, I can post the entire log (but it is long!) - can anyone help me out on this - is there any way, I can deal with this so U can have a full back up of my stuff? I really do not want to not have a back up & send in my notebook with all my data on it as if I wipe the drive & Super Duper keeps failing, I will lose all my stuff. I am hoping it might be something simple to deal with if luck is on my side!! Please kindly help if at all you can! Many Thanks, Bazzy!
