Can't backup with Time Machine

So I have been trying to backup to a WD My Passport Edge 500 GB drive. Never used Time Machine before, but since the OS needs to be updated, I figured now would be the perfect time to start backing up. Have the install disk ready for Snow Leopard, but want to be sure everything is backed up in case of failure.

I set the drive to backup to. It made it to almost 2 GB of almost 250 GB and it stopped, gave an error of Time Machine Error: Unable to complete backup. An error occurred while copying files to the backup volume.

I deleted the database once and did it again. It hung up and errored out again. Any ideas?
