I presume this is because of what happened about 40 days previous?

This sounds like Maxtor does about the same as Seagate - every sector 
read increments the Raw_Read_Error_Rate (and smart does 27 uncached 
sector reads?).
If you `dd if=/dev/hda of=/dev/null`, you may find that the RRER 
increases by about 40,000,000.
All of the normalized values are excellent. However, I'm a little 
suspicious of the error log - the status register is a copy of the 
command register, and the error register is a copy of the features 
register, so the error log is not worth a dime. The last error in it is 
totally confused.

Note to developers: the power-on hours actually appears to be in minutes.
