Palimsest discrepancy

[ergodic]

Has anyone experienced Palimpsest discrepancies? 

Palimsest in Fedora 16 reports a disk (MAXTOR STM3320620AS) as failing: "DISK HAS MANY BAD SECTORS" etc. 
SMART: 197 Current pending Sector Count Value -4 sectors. 

Palimsest in Fedora 17 beta reports the same disk (MAXTOR STM3320620AS) as "OK" 
SMART: 197 Current pending Sector Count 0 sectors OK. 

Obviously one is incorrect, which one? 

Regards.
