time machine is not working on imac intel i7
I just got a new imac intel core i7 which is an upgrade from my power mac G4 MDD which I got in 2003. I transferred all the information from the power G4 using time machine and it worked fine. I then upgraded the OS to 10.6.4 given imac is intel core. All programs are working fine except I am unable to use time machine. It runs for a few gb and then the following error come on time machine buddy:

Stopping backup.
Copied 70375 files (17.4 GB) from volume Macintosh HD.
Copy stage failed with error:11
Backup failed with error: 11
Then when I try to verify and repair the disk, it does do it and keep on showing: " invalid node structure, invalid key length and invalid record count"
I have changed the external hard drive twice so I doubt that is the problem. Please help
