I have been monitoring my HDD for a while now and noticed the following related to the amount of Bad sectors shown in the Disk app:
7 Months Ago - Brand new, sparky, Beam me up Scotty!
3 Months Ago - 3 Bad Sectors
2 Months ago - 17 Bad Sectors
1 Month Ago - 11 Bad Sectors 1 Week Ago - 9 Bad Sectors
3 Days Ago - 5 Bad Sectors
Today - 4 Bad Sectors
Did my HDD suddenly learn to heal?
Does my HDD include a hidden features (Small Elves that fix sectors instead of shoes)?
I know that bad sectors can increase because of usage, but decrease?. the only think I did was lower the temperature since I did what is mentioned here (It is the same HDD) How to lower the HDD temperature so what influences in the decision to show what Bad sectors really are and how many actually are in the HDD.
