Most likely you have a bad sector on your disk. fsck cannot fix this. When 
you write to the disk, hopefully the disk will mark the sector bad, and 
basically hide it. Unfortunately, you cannot mount it to write if it is 
dirty. You can only newfs it, which means goodbye to everything since your 
last backup. After you newfs, you can restore from your backup.
