My drive is failing because of Attribute 190- "Airflow Temperature". Is this correct?

There has been mixed reports about the accuracy of this attribute. Some people have reported it is a debugging attribute for the drive maker. Others have stated that if its in the SMART attributes list, it is important.
Most likely the drive will be last- however there has been no long term study of the correlation between drive failures and this attribute. The recommended course of action is to scan once a week to check for problems and back up all files- just in case.
There is also a preference to ignore failing conditions from this attribute.
<- My drive reports FAILING or FAILED. Is that correct? What should I do? My drive is failing because of Attribute 196- "Reallocated Event Count "- and this is the only reason it is reporting as failing. Is this accurate? ->
