Predicitive Failure Codes

     Greetings.
     
     There are several SCSI drive manufacturers that are claiming the 
     ability to predict drive failure within some number of hours or days.  
     Apparently, when this failure is predicted by the drive, a vendor 
     unique error code is returned in Request Sense Data.  Is there an 
     effort to standardize such error messages?  Does anyone know any more 
     about predictive failure analysis and how the drive can make such a 
     bold assertion?  If you are a manufacturer of such a drive, please 
     contact me with more information.
     
     If there is currently no effort to standardize, is anyone willing to 
     spearhead such an effort?
     
     Thanks.
