When I ran fsck after the first bout of failure, it did report a lot of 
errors.  I do not have a copy of that fsck transcript; however, I have not 
yet run fsck since my second attempt.  Is there a method of capturing the 
transcript that is preferred?

Did fsck report any errors?  Do you have a copy of your fsck
transcript?

The errors you've reported do make me suspicious that there's
something unstable with your hardware...
