Hello Dave, thanks for your answer.
Yes, even with :
- erasing/formatting -several times- the destination drive once I got the error the first time ;
- trashing the app from the source drive (and the associated files) then replacing it with another ;
- repairing the source drive and authorizations
I still have the problem.
The console only says :
2006-04-15 10:52:35.450 SuperDuper![359] ***ERROR OCCURRED: ditto: /Applications/Image Capture.app/Contents/Resources/English.lproj/ImageCaptureHelp/./ImageCaptureHelp.helpindex: Input/output error
I don't have any other information about the drive.
I'm still puzzled by all this ...
