They're both incorrect.  The Fedora 16 "Value -4" (that is, "-4" ==> 0xFFFFFFFC)
probably is a bug [although _where_ is unknown: could be palimsest, could be the
interface hardware, could be drive microcode, ...].  The Fedora 17 "OK" is suspect.
Also check with "hdparm" and other tools, even on other OS.

How old is the drive?  That model number says 3-platter, 320MB, SATA.
If it's three or more years old, then just replace it.  A new drive
is $90 or less in US, and 500GB is available for the same price
and same other specs (size, power, heat, performance, ...).
The data is worth far more than that.
