View Full Version : Input/Output Error

08-30-2008, 08:52 AM
Hard drive on my trusty 7 year old powerbook is starting to go and I'm trying to make a bootable clone of of that drive to an external firewire HD using SuperDuper.

It gets about 3 gigs into the copy and then this error comes up "Input/Output Error". I look at the log and it has a permission problem with WebpageIcons.db located in the Safari folder found in Library.

Anyone encountered this yet? I have all of my important files backed up through drop n drag, but I'd really like to get this bootable clone going.

Can you send your log into me using the "Send to shirt pocket..." button? Alternatively, you could follow the steps in the Troubleshooting section of the User's Guide, which explains how to diagnose this problem...

Right, so that specific file looks damaged on the source; try following the troubleshooting steps to determine whether or not that's the case for sure...

....well just about that is. As the user guide suggested, I tried using Disk Utility to repair the disk, tried copying that bad file elsewhere, tried emailing it, and finally tried deleting it - but nothing would do. Maybe its just located on a bad part of the disk and cannot be changed in any way because the drive is failing. Whatever the case, I did find a workaround.

All I had to do was make a new SuperDuper script that would backup all files EXCEPT that one bad one. So now I've got a perfect working copy of the drive sans that Safari library file "WebpageIcons.db". Don't know what the hell that file does but how important can it be? I can always download Safari and reinstall if necessary.

Can't wait to try restoring all my files once I'm done installing the new drive...

Thanks Dave and thank you SuperDuper for making backups easy.

It couldn't be deleted either? That's rather weird.
