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?
Interpretation of the SMART data can be tricky. There's a longstanding
bug where palimpsest considers numbers of 'bad' sectors that are well
within manufacturers' tolerances to indicate a failing disk:
https://bugzilla.redhat.com/show_bug.cgi?id=498115
and it's possible you hit that in F16 and it's been corrected, at least
for your particular disk, in F17. That '-4' does seem odd, though, as
another poster mentioned. The bug report linked above has some useful
diagnostic steps you can take.
