SuperDuper won't backup drive-giving error code

by markw10 - 4/29/12 2:25 AM

I have a OS X Lion 10.7.3 based Macbook Pro and use the newest version of SuperDuper to do backups. I back up to an OWC external hard drive. I have used this system for around 3 years on multiple laptops/drives with no problems.
For some reason it won't work now on my Macbook Pro. When I backup it fails at a certain part of the backup. I thought it was simply my system had too much open and was running slow so did a restart and didn't open anything other than SuperDuper but that did not fix it. Then I thought it was a bad Firewire 800 cable so tried a 2nd one with no luck. Then I tried a USB 2.0 cable with no luck.
I then figured that either my laptop's hard drive or my OWC hard drive is going bad. I realized that the error where it fails occurs at the same part of the backup almost everytime.
I then realized you can view the log of the backup and I did that and looking at the bottom I see where the problem is. Here is that part of the log:

I don't know enough about this type of thing to know what the means. I use Mozilla Thunderbird for email and Ordered Items is one of my categories on the local computer in Thunderbird.

Does this appear to be a problem with the hard drive or is it possibly some type of corrupt file that I have to remove or repair?

Thanks for your help.
