Too much temptation with this one, Has the OP considered using WD40 
My old notes say:
If the RAW figure for Reallocated Sector Count, Current Pending Sector Count, or Reallocation Event Count is higher than zero, then the drive is throwing up bad sectors. Replace it.
So it looks like the drive is OK.
Although the temperature looks dubious.
As a comparison my laptop:
194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 24 (Min/Max 13/48)
I wonder if idle3-tools would make a difference?
Idle3-tools provides a linux/unix utility that can disable, get and set the value of the infamous idle3 timer found on recent Western Digital Hard Disk Drives......
....Unfortunately, the default timer setting is not perfect on linux/unix systems, including many NAS, and leads to a dramatic increase of the Load Cycle Count value (SMART attribute #193). With the default timer setting, the drive will spin down *every eight seconds* if idle and this may get the spindle motor to burn out in a few months or so.
