This drive is fine.  42C is quite warm for a drive but within acceptable
range for the Caviar Black series.  Max sustained operating temp is IIRC
65C, with a max short term peak temp of 80C.

Below are the critical parameters that inform you of surface defects,
spindle bearing wear, problems with the voice coil actuator hardware or
electronics, and the external interface, i.e. SATA.  Your raw values for
all of these is zero, which means the drive is operating perfectly.
