You should note that the drive won't know a sector it just wrote is 
bad until it reads it....are you sure you actually successfully wrote 
all of that data and that it is still there?

And it is not the writes that kill when you have a drive going bad, it 
is the reads of the bad sectors.    And to create a file, a number of 
things will likely need to be read to finish the file creation, and if 
one of those is a bad sector things get ugly.
