That's interesting. Could you post the log of that disk? I'd like to see how it progressed from when the deterioration set in up to that 9% point.

There is no log, well not AFAIK, the HDD, (a Samsung HD753LJ SpinPoint F1), is over 2 years old and is currently used as transient storage. Although, the features of the drive says Error Logging is supported,
GSmartControl shows that no errors have been logged.
TBH, I'm not that concerned about the remap figure reported mainly for the reason you've picked up, there is no time reference.
I don't know whether the remaps occurred:
a) evenly spaced at 1 every 11 hours or so;
b) all at once within the first month;
c) all at Christmas because I was inebriated and did something stupid;
d) they just appeared through the magic of quantum physics because I observed them.
Putting it into perspective, it's ~819kB out of 750GB. Naturally, Murphy's Law will dictate that it only happens to a significant area of the HDD.
I'd be more concerned if it had reported it that the HDD was unable to remap the sectors.
Interestingly, the Reallocation Event Count shows zero events, it should show the number of successful and unsuccessful sector remaps.

BTW, I'm running WD (640GB & 750GB), Seagate (1.5TB) and Samsung (2x1TB & 750GB) HDDs in my machine, of them all the WD HDDs have the best statistics.....they're also the oldest HDDs in the machine.
