Time Machine crashing during backup

Question

I have been having issues with TM for the past 2-3 days. It worked fine for the past year and has suddenly stopped working and generating errors after every attempt. I have verified, repaired permissions on both my internal HD and the Lacie 1 TB external drive (partitioned into 2x500G, one for TM and one for media). I have also erased the partition and resetup TM but still no luck. The backup seems to fail after copying 1.8GB of data of 178 GB. I have attached a copy of the log from Time Machine Buddy.
Thanks for any help.

Answer 1

Going to give the hardware test a run to see what it comes back with. I am quite confused as I am not seeing any other issues with the computer.
I have been working on computers for years and still do it for a living and can't figure this out for the life of me (The reason I use a mac is because I deal with PC issues all day long). I honestly am considering doing the actual complete wipe and reinstall even though its probably not going to help. I'm at a loss here and its frustrating because I deleted all my old backups as I originally thought it was the HD causing the problem and tried formatting the drive.
Thanks for all your help...Your assistance here is invaluable and you are great at articulating troubleshooting steps.
