Examining specific SMART parameters out of context may be useful for 
someone who is familiar with specific drives, but I suggest including 
the entire report when posting to a mailing list (I typically redact the 
serial number):

# smartctl -x /dev/sda

# smartctl -x /dev/sdb


While SMART reports are mostly standardized, each manufacturer may 
provide specific parameters and/or specific interpretations.  The whole 
report should include model number, hardware version, firmware version, 
etc., of the drive, which can be used to find a manufacturer document 
that explains these details.
