Disks are cheap enough that it's probably not worth the fight to figure 
out what is wrong with this one.  I have some identical Seagate 750G 
drives that I swap regularly and re-sync for offsite copies and one of 
them has started to take about twice as long to complete as the others 
with no indication of problems showing up int the logs.
