Partition Magic 8.0 and Vista

I booted partition magic 8 on the vista machine, and it reported a few errors with hard disk.  I let it fix it.  Afterwards,  it reported a 105 error on the entire hard disk.  I can no longer boot vista now.    My questions:

 

1. Is there any way I can reverse the damage done by PM 8.0 on Vista, like running the latest PM to correct the hard disk error?

 

2. Can I still see the files on hard disk and back them up?
